October 6, 2023	Daniel Rainham Professor, Dalhousie University	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 cities Multiple 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

October 20, 2023	Anya Keefe Occupational & Public Health Consultant	Don’t just shrink it and pink it: addressing the gender gap in PPE Join Anya Keefe speaking IN-PERSON in room SPPH B151 Significant 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.

November 3, 2023	Sahar Derakhshan Assistant Professor of Geography, California State Polytechnic University, Pomona Travis Longcore Adjunct Professor of the Environment and Sustainability, UCLA	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.

Locomotives are everywhere, instrumental to our society’s delivery of goods and economic health. The railway industry is a vast one. In Canada, between 2017 and 2021, the average number of employees in Canadian railway companies ranged between 28,000 to 31,000. These employees covered an average of 100,000,000 train kilometres as well as worked an average of 2,400,000 total train hours per year. This session will cover elements of the railway industry in Canada as seen through the eyes of a hygienist.	Watch Recording
November 24, 2023	Sonja Senthanar Partnership for Work, Health and Safety	Workers’ compensation system experiences of immigrant workers in British Columbia, Canada Workers’ compensation claims data indicate that immigrant workers experience a longer time to return to work following a work injury or illness compared to their Canadian-born counterparts. Extending from this work, we employed in-depth, semi-structured interviews with immigrant workers to explore the contextual reasons for these differences and to gain insights into key areas where changes can be made to improve their work disability experience and reduce inequities.
Decemeber 1, 2023	Shuai Xie Postdoc Fellow, National Institutes of Health	Occupational exposure to organic solvents and risk of bladder cancer Bladder 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.

October 15, 2021	Glen Kenny Professor University of Ottawa	Understanding the limits of heat tolerance in vulnerable populations in the face of rising global temperatures Description: 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. In this presentation, we will examine the unique transformational research conducted by the Human and Environmental Research Unit of the University of Ottawa to define the human physiological tolerance to heat stress and how this practice-changing research is used to generate heat protection solutions to safeguard the health and well-being of all Canadians.

October 22, 2021	Anya Keefe Occupational and Public Health ConsultantPaul Demers Director Occupational Cancer Research Centre	Asbestos Management in Canada: Assessing the Need for a National Standard Description: 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.

December 3, 2021	Cheryl Peters Research Scientist Alberta Health Services	The impact of sex and gender on occupational exposure Description: 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.

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 Peckham PHD Student, Department of Environmental and Occupational Health Sciences at the University of Washington	Precarious Employment and Health in the United States The 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 Brauer Professor, UBC	Health and the built environment: Looking to the future Just 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.

Mar 20	Matilda van den Bosch	Urban 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 27	Hugh Davies	Advancing surveillance protocols for antineoplastic drug exposures in health care settings Abstract: 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.

Sept 13	Angela Yao PhD Candidate	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.	Click here to view the recorded seminar

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.

Oct 4	Andrea Jones PhD Candidate	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 11	Erin McDuffie, PhD – Atmospheric Chemistry Dalhousie University \| Department of Physics and Atmospheric Science	Quantifying the burden of disease from major sources of ambient fine particulate matter: Insights from an atmospheric chemist Air 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.

Oct 18	Occupational & Environmental Hygiene students to present on their 2019 Summer Practicums	1:00pm Minal Pachchigar – Drinking Water Contamination in a Downtown Vancouver Building A tenant at a downtown Vancouver (DTV) building requested consulting company services for the collection of water samples in response to tenant staff concerns regarding drinking water quality. Potable water quality tests were conducted over four days to investigate the cause and provide recommendations. 1:15pm Ehsan Hemmativaghef – Assessment of Occupational Exposures during Laser Engraving Occupational exposures to total and respirable dust, methyl methacrylate, VOCs, formaldehyde and noise during laser engraving and cutting of acrylic based sheets was evaluated based on NIOSH and WorkSafeBC methods. Personal exposure to formaldehyde was found to have the highest risk rate (3 out of 4) followed by respirable dust and noise (2 out of 4). Recommendations for improvement include establishing a preventive maintenance for ventilation systems as well as provision of ventilation system for the supply and distribution of air in the workplace 1:30pm *Soham Parelkar* – Noise Sampling at a BC Health Authority This project examined the noise exposure associated with various occupations through personal noise monitoring at a BC Health Authority	Click here to view the webinar Click on presenters name below for personal Evaluation Form :Minal :Ehsan :Soham
Oct 25	Occupational & Environmental Hygiene students to present on their 2019 Summer Practicums	1:00pm Aaron Agyeman – Prevention and FSII officers exposure to TENORM in oil and gas. Technologically Enhanced Naturally Occurring Radioactive Materials (TENORM) in oil and gas processing develop from the pre-concentration and distribution of radionuclides in oil ad gas. Radionuclides continue to undergo radioactive decay causing the release of alpha, beta and gamma radiation which are harmful to human health. Worksafe field officers conduct investigation and inspections in environments contaminated with TENORM. Therefore, to ascertain compliance and the protection of health and safety a study was conducted to investigate the extent of radioactive exposure for officers during their mandated work. 1:15pm Arthur Leung – Health Hazard Exposure Survey of Workers in Aluminum Pot Lining A health hazard survey was conducted at the Lining Facility located in an aluminum smelting facility, as no exposure monitoring has been performed in the past. This health hazard assessment aims to accomplish the following: Stratify the workers into Similar Exposure Groups (SEG); Determine compliance with regulatory exposure limits; Identify tasks associated with highest exposures; Recommend appropriate controls. 1:30pm Hongjie Yu – Respiratory silica and noise exposure survey of employees in building product industry”. During the summer co-op in 2019, industrial hygiene surveys were taken at a large North American building product company. Employees’ respiratory silica and noise exposures were measured. Results suggest that employees working as ground men and tower operators are at risk of silica and noise overexposure. 1:45pm Sana Javaheri – Occupational Exposure Limit for Hydrogen Sulphide in British Columbia’s Mines. The purpose of this project was to propose a new worker exposure limit for hydrogen sulphide (H₂S) in Table 2-1 of the Health, Safety and Reclamation Code for Mines in BC. This was achieved by identifying sources of H₂S in BC mines, evaluating the H₂S exposures of worker involved in these processes, assessing the accuracy of electrochemical direct reading instruments (DRIs),conducting a literature review of the health effects, reviewing the exposure limits set in other jurisdictions to evaluate their underlying evidence and rationale, and investigating the feasibility of a new limit with regards to practicality of implementation.

Nov 1	Dr. Lawrence Frank, Bombardier Chair Professor Transportation & Health SPPH, UBC	Where Matters: The Health and Economic Impacts of Where We Live There 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.

Nov 8	Matt Shupler 4th year PhD Candidate	The PURE Air Study: A multinational examination of household air pollution concentrations & primary fuel switching determinants Approximately 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.

Nov 22	Dr Alex Bigazzi Assistant Professor, UBC Dept. of Civil Engineering and School of Community and Regional Planning	A closer look at energy expenditure and pollution inhalation during urban cycling: Physics, physiology, and travel behaviour Although 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.

Nov 29	Jennie Christensen	Can 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.
