Is a health environment a right? New CEPA bill says so

National ObserverA new law could soon see toxic chemicals undergo more rigorous assessments aimed at better protecting vulnerable Canadians, the Trudeau government has announced. The proposed bill would bring in sweeping changes to the Canadian Environmental Protection Act (CEPA). It would fast-track the regulatory process for particularly harmful chemicals, making it easier to restrict their use; encourage companies to avoid toxic chemicals entirely; and force manufacturers to be more transparent about the chemicals used in their products. Under the proposed bill, the federal government would “recognize” that every Canadian has a right to a healthy environment and have a duty to protect it.

Air pollutants cost Canada $120B a year: Health Canada

National Observer – Air pollutants have cost Canada $120 billion per year, according to recently released figures from Health Canada, a toll that roughly equals the value of all oil and gas exports. The health burden from pollutants in the air that come from industrial activities like oil and gas extraction, mining, manufacturing, construction, and transportation — as well as natural events like forest fires — contributed to 15,300 premature Canadian deaths in 2016, the most recent year figures are available.

Younger North Americans are exposed to more radon gas due to occupancy biases within the residential built environment

Nature – Residential buildings can concentrate radioactive radon gas, exposing occupants to particle radiation that increases lung cancer risk. This has worsened over time in North America, with newer residences containing greater radon. Notably, residences built in the twenty-first century are occupied by significantly younger people experiencing greater radiation dose rates from radon, relative to older groups more likely to occupy twentieth century-built properties. Newer, higher radon-containing properties are also more likely to have minors, pregnant women and an overall higher number of occupants living there full time.

Study finds wildfire smoke more harmful to humans than pollution from cars

NPR – Tens of millions of Americans experienced at least a day last year shrouded in wildfire smoke. Entire cities were blanketed, in some cases for weeks, as unprecedented wildfires tore across the Western U.S., causing increases in hospitalizations for respiratory emergencies and concerns about people’s longer-term health. A new study finds those concerns are well founded. Researchers say that the tiny particles released in wildfire smoke are up to 10 times more harmful to humans than particles released from other sources, such as car exhaust.

Night-shift work duration and breast cancer risk: an updated systematic review and meta-analysis

BMC Women’s Health – This systematic review and meta-analysis aimed to update the current evidence regarding the relationship between night-shift work duration and breast cancer risk. Based on the overall evaluation of 26 eligible articles, in the short-term night-shift workers, the risk of breast cancer was increased (RR = 1.13, 95% CI: 1.03–1.24), but the increase did not observe in the long-term night-shift workers (RR = 1.08, 95% CI 0.99–1.17). The researchers suggest further studies with adequate information and exact definition regarding night shift work and its duration.

Three-dimensional (3D) printing: Implications for risk assessment and management in occupational settings

Annals of Work Exposures and Health​ – The widespread application of additive manufacturing (AM) technologies, commonly known as three-dimensional (3D) printing, have raised concerns regarding the possible health implications. This review evaluates available data concerning exposure assessment in workplaces and possible effects of 3D printing emissions on humans. The literature demonstrated that a significant fraction of the particles released during 3D printing could be in the ultrafine size range, and increased levels of metals and volatile organic compounds could be detected during AM operations.

Surface contamination with nine antineoplastic drugs in 109 Canadian centers; 10 years of a monitoring program

Journal of Oncology Pharmacy Practice – A cross-sectional antineoplastic monitoring program is conducted once a year with voluntary Canadian hospital centers, since 2010. Twelve standardized sampling sites were sampled in 109 hospital centers between January 31 and June 18, 2020. Cyclophosphamide and gemcitabine were the drugs most frequently quantified on the surfaces. The armrest of patient treatment chairs, the front grille inside the biological safety cabinet (BSC) and the floor in front of the BSC were frequently contaminated. This large-scale study showed reproducible long term follow up of the contamination of standardized sites of Canadian centers and a reduction in surface contamination from 2010 to 2020.

Occupational cancer burden: The contribution of exposure to process-generated substances at the workplace

Molecular Oncology – In this study, researchers illustrate how common occupational exposures are and discuss challenges in estimating their global prevalence and their contribution to the burden of occupational cancer. The population attributable fraction for lung cancer due to occupational exposure has been estimated to be between 18 and 25% in men and 2–6% in women, resulting in lung cancer being the most prevalent occupational cancer. Actions to reduce exposures and research to fill gaps in knowledge adapted to local settings are warranted to mitigate the occupational cancer burden, especially in under-researched settings including low and middle income countries.

More countries act against exposure to radon and associated cancer risks

World Health Organization – More countries than ever before are protecting health from radon exposure, but many still need to take action to mitigate the impacts of this carcinogenic radioactive gas, according to a new WHO survey. So far, a total of 56 countries – over a quarter of all WHO Member States – responded to the WHO radon survey. The vast majority have set national reference levels for homes and workplaces, 44 per cent have developed national radon action plans, and 39 per cent have included it in codes for new buildings. Globally, in 2019, residential radon exposure alone was estimated to have caused 84,000 deaths by lung cancer; in some countries, it is among the leading causes of lung cancer.

The Lung Association in partnership with Take Action on Radon Coalition commends the government of Saskatchewan for including radon mitigation costs under the new home renovation tax credit

Lung Association, Saskatchewan – The Provincial Government’s Home Renovation Tax Credit allows home owners to claim a tax credit of eligible home renovation expenses. The eligible expenses include the cost of labour, professional services, and the building materials required for radon reduction measures. “In a year when we are spending so much time at home, our government is proud to be able to assist Saskatchewan residents in keeping their homes safe,” said Paul Merriman, Minister of Health.

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.
