SPOTLIGHT ON PFAS

New carcinogen profile for PFAS

A profile for per- and polyfluoroalkyl substances (PFAS) is now available. PFAS are a large group of synthetic chemicals that have been used extensively in consumer and industrial products, including food packaging, waterproof clothing, non-stick cookware, firefighting foam, paints, and more. They are highly persistent in the environment and can contaminate the air, soil, and water.

The main route of exposure for the general population is through food and drinking water, while workers are primarily exposed via contaminated dust and air. Two types of PFAS – perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) – were recently evaluated by the International Agency for Research on Cancer (IARC) which classified PFOA as carcinogenic to humans (Group 1) and PFOS as possibly carcinogenic to humans (Group 2B). The new PFAS profile is available here.

Community Profiles: PFAS levels in Indigenous communities across Canada

As a part of our ongoing commitment to Indigeneity, Equity, Diversity, and Inclusion (IEDI), we are featuring a new “Community Profiles” section in our newsletter. This space will be devoted to uplifting and raising the profile of communities that may be at greater risk of exposure to carcinogens, or who have recently made progress in finding solutions to combat exposures.

The Inuit population of Nunavik, Quebec have some of the highest reported per- and polyfluoroalkyl (PFAS) levels among Indigenous communities and in all of Canada, despite their remote location relative to PFAS-emitting industries. This is due in part to diets with the higher reliance on country (traditional) foods like caribou, fish, and marine mammals, which can contain high levels of PFAS. But it is also indicative of a larger issue: PFAS can be transported to the Arctic region from more industrialized areas via atmospheric and oceanic currents. Considering the ubiquity of PFAS, the ability for it to transported across the globe, and the biomagnification in animals and marine life, the environmental harm being experienced by Indigenous communities in the arctic and subarctic regions of Canada is unjustly compounded.

PFAS is not just an important issue for northern Indigenous communities. Many communities that experience systemic disadvantages, particularly those living in close proximity to manufacturing facilities, chemical refineries, or waste disposal sites, face significant health impacts from intense and prolonged chemical exposure. For example, Aamjiwnaang First Nation has multiple sources of PFAS in close proximity to their community, increasing their risk of PFAS contamination through the air and local drinking water.

In August 2024, the Government of Canada released the Objective for Canadian drinking water quality- per- and polyfluoroalkyl substances, which sets forth a drinking water objective for PFAS of 30 ng/L (nanograms per litre). While Indigenous communities, along with the rest of Canada, do not have a permanent monitoring programs in place to detect PFAS levels in drinking water, the new objective will set the bar for future testing and remediation programs.

IN MEMORIAM

Honouring Dr. Thomas Tenkate

On behalf our entire CAREX Canada team and extended networks of friends and colleagues, we honour the memory of our cherished colleague, Dr. Thomas Tenkate, who passed away suddenly in July. Thomas is survived by his wife Katie and his children Abigail and Hudson, and by countless friends, family, and colleagues in Canada, Australia, and beyond.

Thomas had over 30 years of experience in the occupational and public health fields starting in his home country of Australia. He worked for government and with industry for 10 years before moving to academia, where he became the Graduate Program Director at the Queensland University of Technology. In 2011, Thomas moved to Canada to take on the position of Director of the School of Occupational and Public Health at what is now called Toronto Metropolitan University. The undercurrent of his entire professional life was a deep commitment to supporting the health and safety of workers. Thomas was also a dedicated educator and supporter of unions and worker organization in general.

We extend our condolences to any and all who knew him, we celebrate his contributions to occupational health and safety in Canada, and we commit to carrying forward his legacy with the same sense of calm commitment that Thomas always brought to his work.

New Canada-wide survey on household radon exposure

Approximately 1 in 5 (18%) Canadians live in buildings with radon levels at or above the current guideline of 200 Bq/m³, according to a new survey from the team at Evict Radon. These estimates are greater than the previous Cross-Canada Survey (2009-11), which showed approximately 7% of homes at or above 200 Bq/m³.

Radon is the second leading cause of lung cancer in Canada. The new survey, titled 2024 Cross-Canada Survey of Radon Exposure in the Residential Buildings of Urban and Rural Communities, estimates that 10.3 million Canadians have an elevated risk of lung cancer from radon exposure in their homes. Some areas of Canada have more homes with high radon levels, including Atlantic Canada, the Prairies, the North, and Interior BC, but radon levels vary significantly across regions, urban and rural communities, and building types. The only way to know if radon gas is present is to test for it.

Read more about this survey, which was led by the Evict Radon team in collaboration with CAREX Canada, the BC Centre for Disease Control, and Health Canada, here. For more information on radon exposure, visit our website here.

SPOTLIGHT ON CANCER MISINFORMATION AND DISINFORMATION

New publication and grant to combat online cancer misinformation

Misinformation and disinformation about cancer risks, prevention, and treatment is becoming more common, especially in online spaces. Misinformation is false information that is not intended to cause harm (though it may still do so), while disinformation is false information that is intended to cause harm and mislead people. Our team is working to better understand the impact this has on Canadians and develop strategies that will combat online untruths about cancer prevention and treatment.

We recently published a new study on Canadians’ knowledge of cancer risk factors and belief in cancer myths. This research showed that while Canadians were able to identify some well-known cancer risk factors, such as tobacco smoke and sun exposure, they also believed many cancer myths and were unable to recognize other important risk factors. This highlights the need for further investigation to understand and address cancer mis- and disinformation.

Our Principal Investigator Dr. Cheryl Peters was awarded a Challenge Grant from the Canadian Cancer Society to further examine online cancer mis- and disinformation and health literacy in Canada. Alongside co-investigators Professor Timothy Caulfield and Dr. Lin Yang, our research team will investigate how people in Canada access cancer prevention and treatment information and what drives cancer-related mis- and disinformation from online sources. We’ll also be developing a digital strategy with the Canadian Cancer Society to support community partners in combating cancer mis- and disinformation. Read more about this upcoming work on the BC Centre for Disease Control website here, and stay tuned for the results in upcoming newsletters.

Dr. Cheryl Peters and Professor Timothy Caulfield will be also joining Dr. Thomas Piggot, Krishana Sankar, and Marco Zenone in an upcoming webinar, Supporting Patients and Providers in a Sea of Health Misinformation, on June 27, 2024. This free accredited educational session is is open to all health professionals who want to learn how to help patients navigate health misinformation and access recommended resources.

COMMUNITY PROFILES

Industrial benzene emissions in the Aamjiwnaang First Nation

As a part of our ongoing commitment to Indigeneity, Equity, Diversity, and Inclusion (IEDI), we are featuring a new “Community Profiles” section in our newsletter. This space will be devoted to uplifting and raising the profile of communities that may be at greater risk of exposure to carcinogens, or who have recently made progress in finding solutions to combat exposures.

This past April, Aamjiwnaang First Nation declared a state of emergency due to the recorded high levels of benzene in their community. While this is not the first time that the Nation’s air quality has been impacted by nearby industrial pollution, this is the first time Aamjiwnaang have issued an emergency order, with a subsequent Notice of Violation issued by the Nation days later.

Benzene is a known carcinogen associated with leukemia, and can also cause other health concerns including headaches, drowsiness, anaemia, and neuropathies. While there is currently no set hourly limit for benzene, Ontario’s Ministry of the Environment, Conservation, and Parks (MECP) has set the annual average limit at 0.45 ug/m3. On April 25th, one of Aamjiwnaang’s air monitors registered a benzene level of 191 ug/m3.

On the heels of a province-led air exposure review of the Aamjiwnaang and Sarnia area that recommended the MECP “require improved environmental performance and reduced emissions of benzene from local industrial sources”, this latest peak in benzene emissions is evidence that more can done to protect Aamjiwnaang citizens from environmental harm.

In mid-May, the federal government issued an Interim Order to the petrochemical industry in Sarnia, requiring some facilities registering excessive benzene readings to implement vapour-control measures to reduce emissions in the region. The Order was in effect for 14 days, and the Governor in Council approved an extension to the Order for up to two years. The government of Canada is also working to finalize the Reduction in the Release of Volatile Organic Compounds (Storage and Loading of Volatile Petroleum Liquids) Regulations by winter 2024-2025, which would outline the requirements of the petroleum and petrochemical industries to control and lower volatile organic compound (VOC) emissions, including benzene.

SPOTLIGHT ON WILDFIRE SMOKE

Wildfires are intensifying in Canada, increasing the risk of adverse health effects for wildland firefighters

Wildfires are not a recent phenomenon in Canada, though the frequency and severity of fires are on the rise, as climate change continues to intensify weather conditions that increase the risk of wildfires. Of particular concern are the elevated rates of fine particulate matter (PM2.5) in smoke, as well as other known or suspected carcinogens including benzene, polycyclic aromatic hydrocarbons (PAHs) and others.

Wildfire smoke can cause adverse health effects, and some populations, namely wildland firefighters, are at higher risk of these adverse health effects due to their proximity, increased respiration and at times, inadequate respiratory protection. The International Agency for Research on Cancer recently evaluated Occupational Exposure as a Firefighter and published a Monograph reviewing the evidence from epidemiological, animal, and mechanistic studies to assess the carcinogenic hazard to humans of occupational exposure as a firefighter. The Monograph concluded that occupational exposures experienced in firefighting increase the risk of bladder cancer and mesothelioma.

While the Government of Canada continues to update and enhance resources for the general public for staying safe in the midst of wildfire season, there have been questions raised about whether the Air Quality Health Index (AQHI), the primary tool for measuring air quality in Canada, incorporates emerging knowledge about wildfire smoke. Our wildfire smoke summary is available here.

Recent stories from our Carcinogens in the News digest

We’re featuring two stories that appeared in our Carcinogens in the News digest:

The Canadian Cancer Statistics: A 2022 special report on cancer prevalence shows in 2018, an estimated 1.5 million people alive in Canada had been diagnosed with cancer in the previous 25 years; approximately 60% of whom were diagnosed 5 to 25 years ago. The rising prevalence is also attributable to rising cancer incidence, or more cases diagnosed. It is estimated that 233,900 people will be diagnosed with cancer in 2022.

The World Health Organization’s (WHO) International Agency for Research on Cancer (IARC) evaluated the carcinogenicity of occupational exposure as a firefighter. The Working Group classified occupational exposure as a firefighter as carcinogenic to humans (Group 1), on the basis of sufficient evidence for cancer in humans for mesothelioma and bladder cancer. There was limited evidence for cancer in humans for colon cancer, prostate cancer, testicular cancer, melanoma of the skin, and non-Hodgkin lymphoma.
