Forever chemicals are in Canadians' air, water and blood - Transcript

MARK RUFFALO: It's basically what they call forever chemicals. They’re long chain fluorocarbons designed to withstand any kind of breakdown. TAMARA KHANDAKER: That's actor and activist Mark Ruffalo talking about PFAS chemicals, also known as forever chemicals. They've been around since the 1940s and used in everything from non-stick pans to takeout containers to cosmetics and fire retardant. But flash forward to today, and the long lasting manmade chemicals have been found inside Canadian blood samples brought in through the air and dust we breathe and even in our drinking water.

"These chemicals don't get bound up by soils and in the bottom of lakes and oceans. They stay in the water. That means they circulate around, and it also means that these chemicals get into our drinking water," Diamond told CTVNews.ca in an interview earlier this year. The federal government is looking into how to regulate the chemicals, considering an approach of putting PFAS into new classes, different from the individual classification now.

The Canadian government released a report detailing the risks of PFAS exposure and potential management options. This report, which advocates for the regulation of the thousands of PFAS as a whole, will directly influence future regulations and policies surrounding their production and use. This contrasts to previous policy initiatives that targeted PFAS individually.

Water from nearly half of U.S. faucets contains ‘forever chemicals’: study

Drinking water from nearly half of U.S. faucets likely contains “forever chemicals” that may cause cancer and other health problems, according to a government study released Wednesday. The synthetic compounds known collectively as PFAS are contaminating drinking water to varying extents in large cities and small towns — and in private wells and public systems, the U.S. Geological Survey said.

The treatment was designed by researchers at the University of British Columbia, and it utilizes a silica-based material that can absorb up to 99 percent of the forever chemicals found in water. The PFAS are then removed from the material, which can be used again to remove even more toxins. The potential here is exceptional, allowing us to remove these dangerous chemicals from water completely.

'Forever chemicals' found in Canadians' blood samples: report

Toxic "forever chemicals" are being found in the blood of Canadians — and even higher levels are being found in northern Indigenous communities — says a new report from the government of Canada. Health Canada and Environment Canada have released a draft assessment of the science on per- and polyfluoroalkyl substances (PFAS). Both departments propose listing the human-made chemicals as toxic under the Canadian Environmental Protection Act (CEPA). Canadians have until mid-July to weigh in on the proposed change.

So-called “forever” chemicals are being consumed by people on a daily basis from a variety of ordinary materials, revealed a new report. In a study published in Environmental Science and Technology, researchers from the University of Toronto, Indiana University and the University of Notre Dame examined 42 different types of food packaging samples and found the presence of pre-and polyfluoroalkyl substances (PFAS), also known as “forever chemicals” in 55 per cent of the samples taken.

UBC researchers have developed a treatment to remove hazardous ‘forever chemicals’ from our environment. Professor Madjid Mohseni has been at the forefront of the research effort, working with his colleagues in Quebec where polyfluoroalkyl substances, known as PFAS, have been detected in that province’s water sources. “In B.C. unfortunately, the data is lacking so we hope to start gathering that information to determine how widespread the problem is…we are at stage now to take what we have developed from the lab testing and test it out in field studies,” Mohseni said.

US to limit PFAS 'forever chemicals' in drinking water

US to limit PFAS 'forever chemicals' in drinking water

The US government has proposed its first-ever restrictions on six harmful chemicals found in drinking water. Research has suggested over 200 million Americans likely drink water contaminated with PFAS chemicals, which have been linked to a host of health issues, including cancer. But up until now, the pollutants have only been regulated by some US states. The US on Tuesday issued a rule that would require communities to test and treat water for six of the chemicals.

The Environmental Protection Agency is expected to propose restrictions on harmful “forever chemicals” in drinking water after finding they are dangerous in amounts so small as to be undetectable. But experts say removing them will cost billions, a burden that will fall hardest on small communities with few resources. Concerned about the chemicals' ability to weaken children's immune systems, the EPA said last year that PFAS could cause harm at levels “much lower than previously understood.”

University of Waterloo is leading an interdisciplinary team to identify and treat per- and polyfluoroalkyl substances (PFAS) - better known as forever chemicals – in water systems affecting more than 2.5 million Canadians. The Natural Sciences and Engineering Research Council (NSERC) is providing the funding to detect, identify and treat PFAS-contaminated water, the university said in a media release.

PFAS, are a new class of more than 4,000 environmental contaminants whose impact on human health is unknown. PFAS are used in a wide range of products such as cosmetics, textiles, fire-fighting foams and food packaging materials.

A UBC expert on PFAS — also known as forever chemicals — has applied to do research on how much of the toxic substances lurk in B.C.’s drinking water. Exposure to the chemicals, which are widely used in rain gear and non-stick cookware, have been shown to have a wide range of health impacts, including immune suppression, cancer, and cardiovascular disease, said Rachel Scholes, an assistant professor in UBC’s department of civil engineering.

U.S. issues new warnings on 'forever chemicals' in drinking water

The U.S. Environmental Protection Agency on Wednesday released new warnings for synthetic pollutants in drinking water known as "forever chemicals" saying the toxins can still be harmful even at levels so low they are not detectable. The family of toxic chemicals known as per-and polyfluoroalkyl substances, or PFAS, have been used for decades in household products such as non-stick cookware, stain- and water-resistant textiles and in firefighting foam and industrial products.

'Forever chemicals' in the ocean become airborne from sea spray, study says

So-called “forever chemicals,” which are compounds that do not break down easily in the environment, are entering the air from the water through sea spray, a new Swedish study says. Detailing their findings in the journal Environmental Science & Technology, researchers said lab results showed that when bubbles containing perfluoralkyl acids (PFAS) burst at the surface of saltwater, the compounds were aerosolized and entered the air in tiny particles. In order to find out if sea spray could be a vehicle for the compounds to be transported long distances, researchers did field observations at two coastal locations in Norway, collecting more than 100 air samples between 2018 and 2020.
