Asbestos in the Built Environment

Because of its unique properties, asbestos has been used in many buildings in Canada and throughout the world as a component of construction materials. Commercial use of asbestos started in the early 20th century, peaked in the 1970’s and when health effects became prominent, its use steadily declined until its ultimate ban in 2018. Pinchin Ltd. conducted an internal study that examined over 307,000 asbestos samples collected from over 30,000 buildings in Canada.The presentation will summarize the results of the study that demonstrates the prevalence and use of asbestos products in Canada in relation to building materials and construction dates.

Development of the Canadian Environmental Quality Index (Can-EQI): Development and calculation of an index to assess spatial variation of environmental quality in Canada’s 30 largest citiesMultiple characteristics of the urban environment have been shown to influence population health and health-related behaviours, though the distribution and combined effects of these characteristics on health is less understood. The objective of our work was to develop an index of environmental quality for Canada’s largest urban areas and to assess the influence of population size on index values. We identified and selected nine datasets across five domains (outdoor air pollution, natural environments, built environments, radiation, and climate/weather). Datasets were chosen based on known impacts on human health across the life course, complete geographic coverage of the cities of interest, and temporal alignment with the 2016 Canadian census. We selected 30 cities with a population of more than 100,000 people which included 28,026 DAs and captured approximately 55% of the total Canadian population. Can-EQI scores ranged from 21.1 to 88.9 out of 100, and in Canada’s largest cities were 10.2 (95% CI: −10.7, −9.7) points lower than the smallest cities. Mapping the Can-EQI revealed high geographic variability within and between cities.Watch Recording

Don’t just shrink it and pink it: addressing the gender gap in PPEJoin Anya Keefe speaking IN-PERSON in room SPPH B151Significant numbers of women report that their PPE does not fit properly, it is uncomfortable to wear, and the selection of women-specific PPE is inadequate. Despite evidence that anthropometric differences exist between the sexes, PPE continues to be designed for “all workers” based almost entirely on male anthropometry. This is problematic as research on the gendered and sexual division of labour – and its impact on occupational health and safety – reinforce the need to pay attention to sex and gender differences in exposures and hazards as well as the unique needs of each sex in mitigating those hazards and risks.Watch Recording

Extreme heat exposure dynamics and heat-refuge strategies: what can we learn from smartphone users?Extreme heat is the most deadly of weather disasters and individual exposure depends on individual location through the day and night. Anonymized location data from smartphone users makes possible investigations of individual-level extreme heat exposure patterns and heat-refuge strategies that were previously unimaginable. Using a two-month dataset of smartphone locations in Los Angeles County during the record-breaking summer of 2017, we explore exposure and refuge-seeking strategies surrounding cooling centers, parks, and pedestrian shade use to gain insights on adaptation and mitigation strategies to protect public health in communities facing extreme heat events.Watch Recording

Occupational exposure to organic solvents and risk of bladder cancerBladder cancer has been linked to several occupations including those with solvent use. In this project, we evaluated occupational exposure to solvents by integrating a job-exposure matrix with exposure-oriented modules capturing within-job, respondent-specific details about tasks conducted on the job and chemicals handled. Using these data, we found that lifetime, cumulative exposure to benzene, toluene and xylene as a group (or BTX) may increase the risk of bladder cancer.

Hazardous Drug Exposure Prevention Program (HazDEPP): A new approach to reducing risk to healthcare workersThis seminar will describe a study in progress in BC hospitals and cancer care centers aimed at investigating novel ways of reducing the risks from inadvertent exposure to antineoplastic drugs. The study (HazDEPP for short) implements a sampling strategy developed by the investigators that will be used to generate target “hygienic guidance values” for exposure risk assessment purposes. Also, the study will implement/augment communications channels within and between health authorities to encourage sharing of risk mitigation information and exposure data. It is hoped this will help clinics understand where and when exposure risks are increased, to identify best control practices, and to help to continually reduce exposures in the absence of OEL’s. We’ll discuss the study motivation, objectives, design, and progress to date. Watch Recording                 This seminar is incomplete due to a building evacuation at that time.

Review of a mass casualty event: Mortality during the 2021 heat dome
The 2021 heat dome was the deadliest weather event in Canadian history, with an estimated 740 excess deaths in British Columbia (BC). These deaths were not uniformly distributed across the population; they were concentrated in areas with higher deprivation and lower green space.

Confined Spaces in BC – What does the Future Hold?
Confined spaces are not the type of places in which people normally work. The risk of an accident is greater and minor mistakes can have major consequences. Eighteen workers have died in confined spaces in B.C. since 2000 and many others have been injured. There are many hazards that can be encountered including engulfment or immersion, exposure to toxic gases or vapours, oxygen deficiency, and flammable atmospheres. Come to this session and learn about the types of confined spaces found in commercial and industrial facilities and the hazards within them. WorkSafeBC is currently reviewing Part 9 of the regulation, which covers confined spaces.

Evaluating the impact of built-environment factors on sleep disruption
The quality of your sleep depends on many things, but one overlooked and potentially modifiable influence is where you live. Using a dataset of ~25,000 adults from the BC Generations project (BCGP) cohort, we assessed self-reported sleep duration in relation to the built environment. Built environment metrics included light-at-night, greenness, road proximity, and air pollution (PM2.5, NO2, SO2), as linked to our BCGP participants’ postal codes by the Canadian Urban Environmental Research Consortium. Single and multi-exposure analysis results will be discussed.

A comparison of greenspace metrics and measurement methods, and the relationship with neighbourhood walkability and deprivation in Metro Vancouver
Along with other environmental exposures, neighbourhood greenspace and walkability have been linked to numerous health behaviours and health outcomes. There are several different metrics and methods commonly used to quantify neighbourhood exposure to greenspace. This project compares the use of four greenspace metrics and two different measurement methods (circular and network buffers) using 6-digit postal code level data from Metro Vancouver. This project also looks at whether neighbourhood walkability is associated with greenspace exposure, and how these neighbourhood characteristics relate to local area social and material deprivation.

Using wastewater to test for SARS-CoV-2 and variants as a supplementary COVID-19 surveillance toolWastewater testing for SARS-CoV-2 in Metro Vancouver has become a vital surveillance tool providing information on community transmission that can be used to initiate interventions and policies to minimize the disease spread as part of the pandemic response. A powerful community-based tool that is independent of healthcare seeking behaviours (i.e., clinical testing, vaccine status) and one that builds on existing COVID-19 surveillance programs.
The presentation will provide an update on the progress pertaining to using wastewater testing as 1) a population-level COVID-19 surveillance tool in Metro Vancouver communities 2) a targeted building-level COVID-19 surveillance tool at UBC residences, and 3) leveraging lessons learned to apply to new projects beyond COVID-19.

Understanding the limits of heat tolerance in vulnerable populations in the face of rising global temperaturesDescription: By 2050, average summer temperatures in many areas across Canada will exceed 30°C (humidex equivalent exceeding 40°C). This will be paralleled by a near 5-fold increase in the number of extremely hot days from current levels. In response to this threat to population health, we must advance our understanding of the impacts of heat stress so that we can help Canadians adapt to the impacts of rising temperatures, which includes protecting workers in Ontario’s vital industries.

Asbestos Management in Canada: Assessing the Need for a National StandardDescription:  Effective management of asbestos is contingent on accurately identifying its location and condition, assessing the risk of exposure to workers and the public, and selecting an appropriate strategy to eliminate or control the risk. This presentation will highlight the findings of a recent research project undertaken for the Canadian Standards Association to explore potential gaps and best practices in asbestos management in Canada and to determine if there is a need for the development of a national standard. Our research identified important gaps and inconsistencies in how asbestos is currently managed in Canada – in particular, in the regulations governing personnel qualifications and competency, thresholds for what constitutes asbestos-containing materials, and the disposal of asbestos-containing materials – and confirmed that there is an appetite for a national asbestos management standard. Such a standard could benefit regulators, employers, workers, and the public alike by creating a transparent and uniform playing field throughout Canada, helping to ensure that asbestos exposure is minimized regardless of where you call home.Watch Recording

December 3, 2021Cheryl PetersResearch Scientist Alberta Health Services The impact of sex and gender on occupational exposureDescription: A vast shift in the Canadian labour force occurred in the 1970s as women increasingly moved into the paid work force, though the types of jobs they took on were narrowly defined. There is a general perception that the gendered division of labour has lessened over time, but has it? Additionally, sex and gender both have influences on the ways in which men and women and gender-nonconforming people experience occupational hazards, but until very recently, safety standards and indeed occupational epidemiology were by and for men only.
This presentation will provide a brief history of the gendered division of labour in Canada and describe the ways that both sex (biology) and gender (social constructs) can influence occupational exposures and disease, using recent and relevant Canadian examples.

Jan 24Sonja SenthanarPostdoctoral Fellow        School of Population and Public HealthEffects of work injury and RTW on family of precariously employed workersThe impact of work injury and the return to work process on family members of injured workers has often been characterized in the context of standard than precarious jobs. Drawing on 19 in-depth interviews with precariously employed workers and employers, we identified three areas where workers’ compensation policy and employer processes did not fit well with the situations of precarious workers in Ontario. Consequently responsibility fell on family members to provide instrumental and financial support whileClick here to view the webinar
Jan 31Patrick BaylisAssistant Professor, Vancouver School of EconomicsUnderstanding Defensive Health Behavior: Evidence from Pollution Masks in Delhi.Air pollution in Delhi, India is among the highest in the world, but few residents choose to self-protect using particulate filtering masks. In this project, results were documented from two field experiments designed to understand the factors influencing mask use. In the first, differences in income levels and experimental variation in information, experience with masks, and perception of social norms were found to affect respondents’ likelihood to purchase masks, but demand remained low relative to other highly polluted cities. The second intervention took advantage of a public intervention of unprecedented scale: the Delhi municipal government distributed 5 million masks during the 2018/2019 pollution season. Mask effectiveness and social acceptance beliefs did not seem to change in this intervention.Click here to view the webinar
Feb 7 Trevor PeckhamPHD Student, Department of Environmental and Occupational Health Sciences at the University of WashingtonPrecarious Employment and Health in the United StatesThe dramatic changes in the organization of work over the last several decades—including the general shift toward more flexible and competitive employment practices—have not been adequately examined from a public health perspective. To do so, traditional models of work and health research need to be expanded beyond a sole focus on work tasks or physical and social environments to include the relational and contractual aspects of employment that may also impact health. Here we examine the association between the multidimensional construct of employment quality (EQ)—defined as the terms and conditions of the employment relationship, such as contract type, wage/benefit levels, and employee representation—and workers’ health in two nationally representative U.S. surveys. Using cross-sectional data from the General Social Survey and a latent class analysis measurement approach, we identify eight disparate patterns of EQ.Click here to view the Recorded Seminar
Feb 14 Michael BrauerProfessor, UBCHealth and the built environment: Looking to the futureJust over 50% of the global population is urbanized, with cities expected to absorb all future population growth. In general, urban populations are healthier, with improved access to services and healthcare. Densely populated cities also play a key role in efforts to reduce emissions related to global warming. Yet, cities face significant challenges, especially those in the rapidly developing megacities of low and middle income countries. Urban design and management and the ways that we interact with this “built environment” can profoundly impact health. Air pollution, noise, mobility options and land-use, among others, play a role and interact in multiple, complex ways.  Understanding these interactions and using this knowledge to shape our cities as they grow has the potential improve population health and build resilience to climate change.  In this presentation I will review a number of analyses using cohorts and linked administrative data combined with geospatial estimates of environmental exposure to examine built environment-health linkages, describe emerging trends, and discuss implications for population healthClick here to view the Recorded Seminar

Mar 20 Matilda van den BoschUrban natural spaces and public health: a matter of challenges or common sense?Over the last decade, research on human health impacts of urban natural spaces has rapidly developed. An increasing number of epidemiological studies demonstrates direct and indirect health benefits by exposure to urban green and blue spaces. While these studies have significantly contributed to confirming associations between nature exposure and various health outcomes, a number of challenges remain before evidence on mechanisms and causality can be established. These challenges range from uncertainty about optimal exposure measures to what physiological effects can be expected from nature contact. Nevertheless, the side effects of “urban green interventions” occur limited. By taking also co-benefits, such as increased biodiversity and climate change mitigation from urban natural spaces, into account there seems to be little to lose from a policy perspective by advocating for more natural spaces in our cities, although the evidence is still insufficient. This presentation will provide an outline of the current evidence level and present research challenges in on-going studies around urban nature and human health. It will also discuss the prevailing discourse around pathways and mechanisms. Finally, the goal is to initiate a debate around opportunities and risks with taking a “nothing-to-lose” approach to urban green initiatives across the world.Click here to view the webinar
Mar 27Hugh Davies Advancing surveillance protocols for antineoplastic drug exposures in health care settingsAbstract: The number of people receiving antineoplastic drug treatment for cancer is increasing as the population ages and more people are diagnosed with cancer. While these drugs are powerful tools in the fight against cancer exposure to these drugs can also cause genetic damage miscarriages and cancer in otherwise healthy people. Despite the dissemination of safe handling practices, healthcare workers and others such as veterinarians continue to be exposed through surface contamination. Guidelines such as USP Chapter 800 call for routine workplace surveillance but do not provide detailed guidance on how this should be done  or how to interpret surface wipe samples.  The SURveillance For AntiCancer drugs Exposure Study (SurFACES) sampled up to 20 different surfaces monthly at nine facilities in the US and Canada for one year, and obtained 2000 samples, each tested for 11 antineoplastic drugs.  In this presentation we will characterize exposures found at the sites, discuss spatial and temporal patterns and determinants of exposures, and discuss how the findings can be used to provide improved AD surveillance guidance to practitioners.Click here to view the webinar

Assessing Sub-Daily Exposure to Wildfire Smoke and its Public Health Effects in British Columbia
Inhaling smoke emitted by wildfires can affect human health. This is a growing concern for public health as wildfires will occur more frequently and affect more communities under the changing climate. This research aimed to improve our ability to monitor wildfire smoke exposures every hour at different locations in British Columbia during wildfire seasons, and to study whether more people call the ambulance during hours with more smoke. The findings show that ambulance calls for heart and lung conditions increased within one hour of exposure to smoke, while calls for diabetic conditions increased after 24 hours. These results suggest that the health effects from wildfire smoke can occur soon after exposure, and actions to reduce exposure should be taken promptly.

Occupational & Public Health Consultant
Determining causation and creating an exposure history for long latency occupational disease claims – challenges and practical toolsDespite studies showing that occupational exposures are responsible for approximately 2 to 10 percent of all newly diagnosed cancer cases, many cancers are not recognized as being work-related and consequently not filed with the workers’ compensation system. This presentation will provide an overview of the challenges and potential solutions in better establishing evidence of exposure that not only shows medical causation, but also meets the test of legal causation. It will discuss the role of epidemiology in determining a general causal link between a disease and an occupational exposure as well as the need to build a comprehensive occupational history to answer the question of whether an individual work developed the disease as a result of their job.Click here to view the recorded seminar

Anxiety and Depression disorders among workers with Musculoskeletal injury in British Columbia
Anxiety and depression are leading causes of global disability and frequently co-occur with physical health conditions. The purpose of this research was to describe the occurrence of anxiety and depression disorders among workers with musculoskeletal work injury in British Columbia, and to investigate the impacts of these disorders on work disability outcomes. Approximately 1 in 10 men and 3 in 10 women were found to have a recent or current anxiety or depression disorder at the time of musculoskeletal work injury, and both pre-existing and new onset anxiety and depression disorders were associated with longer work disability. Collectively these results support the inclusion of anxiety and depression disorders as part of the disability management plan for workers with musculoskeletal work injury.

Oct 11Erin McDuffie, PhD – Atmospheric ChemistryDalhousie University | Department of Physics and Atmospheric ScienceQuantifying the burden of disease from major sources of ambient fine particulate matter:   Insights from an atmospheric chemistAir pollution, specifically fine particulate matter (PM2.5) in outdoor air, is recognized by the Global Burden of Disease (GBD) as the leading environmental risk factor for human health, attributable to 7.5% of all deaths in 2016. To reduce exposure to ambient PM2.5, contributions from major emission sources must be quantified. Previous studies have identified coal and residential emissions as dominant sources in polluted regions in Asia and fossil fuel emissions as dominant global sources. These studies, however, have been limited to particular regions or have focused on large, aggregate emission sectors. Here, we expand upon previous work and utilize recent updates to anthropogenic emission inventories and atmospheric chemical transport modeling to quantify the source- and fuel-specific PM2.5 exposure levels for all 195 countries and territories currently included in the GBD. This presentation will focus on methods used to quantify PM2.5 exposure levels and discuss ongoing collaborations to quantify the burden of disease from all major sources.Click here to view the webinar

Where Matters:  The Health and Economic Impacts of Where We LiveThere is a public health crisis happening right now. Total health expenditure in Canada was estimated to be up to $253.5 billion ($6,839 per person) for 2018. This represents 11% of Canada’s gross domestic product according to the Canadian Institute for Health Information. For example, obesity, high blood pressure, and diabetes place tremendous pressure on our healthcare system.  There is an increasing consensus that the postal code of the neighbourhood where we live is as important as our genetic code. Studies have shown that land-use decisions and transportation investments to enhance neighborhood walkability and access to green space can significantly affect how you travel and your physical activity, and exposure to air pollution, traffic safety and crime, and noise.  Very few studies have examined how transportation investment, neighbourhood walkability and access to green space are associated with less chronic disease and lower health care cost.  To date, existing evidence used to inform major transportation investment decisions have rarely accounted for the potential health impacts and related costs of these factors.The Where Matters Study aims to incorporate health into local and regional policy-making by examining the multiple pathways linking the way our communities are planned and designed with people’s travel and physical activity patterns, chronic disease risk and health care cost.Click here to view the recorded seminar
Nov 8Matt Shupler4th year PhD CandidateThe PURE Air Study: A multinational examination of household air pollution concentrations & primary fuel switching determinantsApproximately 2.5 billion individuals (~40% of global population), primarily in rural areas of Asia (>1.5 billion), Sub-Saharan Africa (>500 million) and Latin America (>50 million) are exposed to harmful household air pollution (HAP) from cooking and heating with polluting fuels (e.g. wood, crop waste, animal dung, coal) in rudimentary stoves. Exposure to HAP was the second highest environmental risk factor in the Global Burden of Disease (GBD) 2017, with an estimated 1.6 million attributable deaths annually. Residential combustion of polluting fuels is also a major contributor to outdoor air pollution and emissions of climate-forcing agents, including up to one-third of global anthropogenic emissions of black carbon.Few multinational studies have examined multilevel (e.g. household, community, national) factors associated with households switching from polluting to clean (gas, electric) primary cooking fuels. Longitudinal epidemiological studies of HAP exposure are also sparse due to the financial and time intensity associated with such studies. The Prospective Urban and Rural Epidemiology (PURE)-Air study, one of the largest HAP exposure assessments to-date, was carried out among rural communities of eight countries: Bangladesh, Chile, China, Colombia, India, Pakistan, Tanzania and Zimbabwe. The study design enabled an examination of physical, environmental and contextual determinants of primary cooking fuel switching and household air pollution concentrations. The concentrations measured in the PURE-Air study will be used in one of the largest epidemiological analyses of cardiovascular and respiratory disease burden due to cooking and heating with polluting fuels.Click here to view the recorded seminar

Nov 22Dr Alex BigazziAssistant Professor, UBC Dept. of Civil Engineering and School of Community and Regional PlanningA closer look at energy expenditure and pollution inhalation during urban cycling: Physics, physiology, and travel behaviourAlthough urban cycling is widely known and promoted as physically active transportation, the actual physics of utilitarian cycling have been given little attention in transportation engineering and planning. In contrast, the field of sports science has developed detailed data and models of road bicycle performance, but only for sport and racing cyclists. What can we learn about utilitarian cycling by integrating knowledge of the physical attributes of bicycles and cyclists? Findings will be presented from recent and ongoing studies aiming to quantify these relationships and enhance travel analysis tools with an understanding of the physical aspects of cycling.Click here to view the recorded seminar
Nov 29Jennie ChristensenCan a single strand of hair be used to monitor exposure to toxic metals?Hair is a growing keratinous tissue comprised of sulfur. As such, the sulfur in the hair can bind the many elements present in circulating blood, including toxic metals. Since hair is metabolically inert once formed, the elements retained in the tissue become locked in, so as the hair grows it can record changes in blood element concentrations over time. Using laser ablation on single strands of hair, exposure histories can be revealed for toxic metals. But, there are some caveats, including external contamination by air, water, and hair treatments. Here we will discuss occupational exposure to lead and other metals, compare hair and blood concentrations, effects of contamination on hair concentrations, examine another growing keratinous tissue (nails) for metal monitoring, and provide forensic case studies from an inadvertent poisoning event, and the historic Franklin Expedition.Click here to view the webinar
