July 24 - Best of Quirks: PFAS Science
We look at the potential health effects about this new class of 'forever chemicals,' how they spread around the world - even to remote parts of Northern Canada - and the regulations that scientists say need to change.
A new class of 'forever chemicals' is an emerging threat to our health and environment
PFAS chemicals are in 98% of Canadians’ blood and could make COVID-19 infections worse
How 'forever chemicals' have come to contaminate even the most remote parts of Canada
Toxic PFAS chemicals travel the world by water and air from contaminated locations, but they can concentrate in the north.
'Forever chemicals' can have far-reaching consequences, need more regulation in Canada, scientists say
Chemicals known as PFAS are everywhere. They can affect the environment and your health — and may even make you more susceptible to COVID-19.
