Population-level estimates of workplace exposure to secondhand smoke in Canada

Canadian Journal of Public Health - This study estimated the number of workers exposed to SHS in Canada in 2006 and 2016 and their level of exposure. The study authors found that the number of exposed workers decreased by 20% from 520,000 in 2006 to 418,000 in 2016, and that trades, transport and equipment operators, and workers in primary industry had the highest rates of overall exposure. The findings can help prioritize high-risk groups for interventions and inform studies of the burden of occupational disease. Read more »

Asbestos still leading cause of work-related deaths in the province: WorkSafe Sask.

CTV News - Disease related to asbestos exposure continues to be the leading cause of death in the province, WorkSafe Saskatchewan says. Asbestos accounts for 23 per cent of 388 work-related deaths in Saskatchewan between 2009 and 2018, WorkSafe said in a news release. Many homes and buildings built before 1990 still contain asbestos, so contractors and homeowners doing renovations may be putting themselves at risk of exposure to asbestos. Read More »

BC State of the Air Report

BC Lung Association - The 2019 BC State of the Air Report is now available. Published annually by the BC Lung Association’s Air Quality and Health Steering Committee, the report provides a snapshot of key air quality issues across the province and includes articles on volatile organic compounds (VOCs), air quality sensors and wildfire smoke.

Exposure to crystalline silica in Canadian workplaces and the risk of kidney cancer

Occupational and Environmental Medicine - The causes of kidney cancer are not well understood although occupational exposures are thought to play a role. Crystalline silica is a known human carcinogen, and despite previous links with kidney disease, few studies have investigated its association with kidney cancer. Researchers addressed this knowledge gap using a population-based case-control study of Canadian men. Their study did not find that occupational exposure to crystalline silica increases risk of kidney cancer in men. Read more »

‘Like being in prison’: Neighbours worry while province studies cancer rate near former Domtar site

The Chronicle Herald - Residents near the former Domtar site say they feel there’s nothing they can do while the province looks into why that area has elevated rates of breast, endometrial and lung cancer compared to the rest of Alberta. Last spring, residents near the 37-hectare former Domtar Inc. wood-treatment operation received letters warning their homes were near land contaminated primarily with dioxins and furans. Read more »

Mortality risk and fine particulate air pollution in a large, representative cohort of U.S. adults

Environmental Health Perspectives – Epidemiological and related evidence implicates exposure to fine particulate matter (PM2.5) air pollution as contributing to cardiopulmonary disease, lung cancer, and infant mortality, as well as the global burden of disease. This study observed, in a large, representative, contemporary cohort of U.S. adults, that long-term exposure to PM2.5 air pollution was associated with elevated risks of early mortality. Read more »

Consulting on the future of chemicals management in Canada

Health Canada – Health Canada is exploring ways to enhance the protection of workers from exposure to chemicals by integrating and leveraging the information, tools, and/or technical expertise of the Chemicals Management Plan and Health Canada's Workplace Hazardous Products Program. The purpose of this consultation is to solicit feedback on the proposed elements and activities outlined in the report. Read more »

Carcinogenicity of night shift work

The Lancet Oncology – In June, 2019, 27 scientists from 16 countries met at the International Agency for Research on Cancer (IARC) in Lyon, France, to evaluate of the carcinogenicity of night shift work. The Working Group classified night shift work in Group 2A, “probably carcinogenic to humans”, based on limited evidence that is causes breast, prostate, and colorectal cancer in humans, sufficient evidence of cancer in experimental animals, and strong mechanistic evidence.

Burden of non-melanoma skin cancer attributable to occupational sun exposure in Canada

International Archives of Occupational and Environmental Health – This study aimed to quantify the health burden of non-melanoma skin cancers among outdoor workers in Canada. In 2011, 6.31% (4556 cases) of non-melanoma skin cancer cases were estimated to be attributable to occupational exposure to solar ultraviolet radiation. These estimates of the burden of non-melanoma skin cancer in Canada identify the need for further prevention efforts, particularly in agriculture and construction. Read more »

Prostate cancer risk decreases following cessation of night shift work

International Journal of Cancer – Night shift work has been associated with breast and prostate cancer. Recent studies on breast cancer indicate that risk is highest in women with current night‐shift work and decreases with time since last night‐shift work. The study found a pattern of time‐related decrease in prostate cancer risk following night shift work with a nearly null association 20 years after last exposure that has also been observed for breast cancer.

Sun Safety in Canada Infographic

CCOHS - People who work outdoors are vulnerable to the sun’s rays. Exposure to ultraviolet radiation (UV) can cause sunburn, premature skin aging, eye damage and skin cancer. Skin cancer is the most common cancer in Canada and the rate continues to rise, yet it is one of the most preventable. This infographic outlines ways employers can support outdoor workers, including the development of a sun safety policy, and tips to reduce the risk when working outside. Read more »

Case-control investigation of occupational lead exposure and kidney cancer

Occupational and Environmental Medicine - Lead is a suspected carcinogen that has been inconsistently associated with kidney cancer. To clarify this relationship, researchers conducted an analysis of occupational lead exposure within a population-based study of kidney cancer using detailed exposure assessment methods. The findings of this study did not offer clear support for an association between occupational lead exposure and kidney cancer. Read more »

Solar ultraviolet radiation exposure among outdoor workers in three Canadian provinces

Annals of Work Exposure and Health - Solar ultraviolet radiation (UVR) exposure places outdoor workers at risk of skin cancer and exposure is difficult to control. In response, the Sun Safety at Work Canada (SSAWC) project was undertaken (2014–2016). The purpose of this substudy was to characterize the UVR exposure levels of outdoor workers in the SSAWC project. Read more »

New Canadian Strategy for Cancer Control released

Canadian Partnership Against Cancer - The Canadian Partnership Against Cancer (CPAC) has released their Canadian Strategy for Cancer Control. The Strategy is a 10-year roadmap that focuses on long-term, sustainable impact in cancer control and improving equity in the cancer system, including First Nations, Inuit and Métis priorities.
