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.

Determining causation and creating an exposure history for long latency occupational disease claims – challenges and practical tools

Despite 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.

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.

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

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.

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.

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.
