The burning question: How to tackle air pollution and health threats from wood stoves?

National Observer – Many rural residents’ health is at significant risk due to high levels of airborne pollutants from wood-burning stoves, both indoors and out, said Michael Mehta, who specializes in environmental and health risk issues. “People in the rural parts of Canada should have some of the cleanest air in the country,” said Mehta. “But, actually, some have polluted air that is considerably worse than any city, and wood stoves are the main contributor.” Wood smoke contains carbon monoxide, volatile gases, and cancer-causing chemical compounds, but it is the fine particulate matter, or PM2.5, that is of particular concern to human health.

Wildfires take over from industry as major source of cancer-causing air toxins: study

CTV News – Wildfires have taken over from industry as a major source of a group of cancer-causing chemical toxins in the air, Environment Canada says. The first national assessment of polycyclic aromatic compounds in more than 25 years has found that air has improved around aluminum and steel plants. But wildfires and vehicles have stepped in to keep average concentrations at about the same level that they were in the 1990s, says federal researcher Elisabeth Galarneau.

Racial disparities in occupational risk and lung cancer incidence: Analysis of the National Lung Screening Trial

Preventive Medicine – The relationship between racial disparities in occupational risk and lung cancer diagnosis is not well defined. This study examined occupational exposure to asbestos, silica, and other workplace chemicals, fumes, or dusts as reported in the National Lung Screening Trial (NLST). The NLST data showed racial disparities of lung cancer development.

Website launch: Ontario occupational disease statistics

Occupational Cancer Research Centre – The Occupational Cancer Research Centre (OCRC) has partnered with the Canadian Centre for Occupational Health and Safety (CCOHS) to develop an interactive website to communicate results from the Occupational Disease Surveillance System (ODSS) and other data sources on occupational disease in Ontario. Results are currently available for the construction, healthcare, metal manufacturing, mining, and transportation sectors.

Canadian home radon exposure on the rise due to pandemic

Financial PostEvict Radon, a Canadian non-profit organization and team of university scholars dedicated to solving Canada’s large and worsening radon-gas exposure problem, has launched a new survey to understand the global pandemic’s impact on residential radon exposure. The study was developed by Evict Radon researchers Drs. Cheryl Peters and Aaron Goodarzi, and is Canada’s largest COVID-related analyses of shifting radon exposure.

Long-term low-level ambient air pollution exposure and risk of lung cancer – A pooled analysis of 7 European cohorts

Environment International – The aim of this study was to address the relationship between long-term low-level air pollution (PM2.5) exposure and lung cancer incidence. The results show that exposure to PM2.5 was associated with higher risk of lung cancer. Long-term ambient PM2.5exposure at the residential address may contribute to lung cancer incidence even at concentrations lower than current EU limit values (25 µg/m3) and possibly WHO Air Quality Guidelines (10 µg/m3).

What new Ontario-led research says about mesothelioma

TVO – New research suggests that older adults and women are getting mesothelioma in increasing numbers. “The really high asbestos exposures that people got in workplaces are becoming less common,” says Paul Demers, director of the Occupational Cancer Research Centre at Ontario Health. “But lower exposures from asbestos that’s in buildings where people are living in — that’s gradually escaping into the environment — will become more important over time.”

Screening-level assessment of cancer risk associated with ambient air exposure in Aamjiwnaang First Nation

International Journal of Environmental Health Research – The manuscript reports findings from a screening-level assessment of cancer risk from outdoor air in Aamjiwnaang First Nation. Ambient air pollution can contribute to cardiovascular/respiratory diseases, and certain types of cancer. Outdoor air concentrations were mapped and the Lifetime Excess Cancer Risks (LECR) associated with long-term exposure to known carcinogens were estimated. ​

Canadian Cancer Statistics: A 2020 special report on lung cancer

Canadian Cancer Society – This special report provides new, detailed estimates of lung cancer incidence, mortality, survival and prevalence in Canada. It also provides information on important and emerging issues related to lung cancer, such as risk factors, screening, treatment and equity.

Quebec to lower acceptable limits of asbestos in any workplace

Montreal Gazette – Quebec is lowering the acceptable limits of asbestos permitted to be in the air in any workplace. The new regulation would lower the acceptable limit to 0.1 fibres per cubic centimetre for all asbestos types, according to Quebec’s workplace safety board, the Commission des normes, de l’équité, de la santé et de la sécurité du travail (CNESST). The new rules bring the province in line with norms already in place in Canada and throughout North America, the CNESST said.

How Ottawa-Gatineau residents perceive radon health risks

Telfer School of Management – Researchers examined how Ottawa-Gatineau residents perceive the health risks of radon exposure. They sought to determine what encourages and hinders residents to test their homes and when they felt the need to adopt appropriate preventive measures.

Comparing the costs, benefits, of silica dust prevention methods for construction workers

Institute for Work and Health – Worksites can use different prevention methods to reduce silica dust exposure, including the wet method, local exhaust ventilation, and personal protective equipment. A team of researchers found a combination of all three methods can avert the highest number of lung cancer cases (107 cases per year). However, the most cost-beneficial approach is the wet method used in combination with local exhaust ventilation.

Occupational asbestos exposure after the ban: a job exposure matrix developed in Italy

European Journal of Public Health – The objective of this study was to develop a job exposure matrix (JEM) in order to provide summary information for the period 1996–2016 on the magnitude of occupational exposures to asbestos fibres in Italy after the ban. A total of 46,422 workers (86% male) were estimated to be potentially at risk of exposure to asbestos in the sectors of asbestos abatement.

Fine-particle air pollution has decreased across the US, but poor and minority communities are still the most polluted

The Conversation – Air pollution contributes to as many as 9 million premature deaths worldwide each year. In a newly published study, researchers leverage newly available data that captures PM2.5 concentrations at more than 8.6 million distinct U.S. locations from 1981 through 2016. The results show that the neighborhoods and population groups that were most exposed to fine particle pollution 40 years ago – disproportionately low-income and minority communities – are still exposed to higher pollution levels.
