'Forever chemicals' can have far-reaching consequences, need more regulation in Canada, scientists say
News
7 Nov 2020 | CBC Radio Canada
Unlike pesticides or pharmaceutical drugs, a significant portion of the more than 6,300 different types of PFAS on the market have little to no data on their use, toxicity and chemical structure and are not currently regulated or restricted in Canada. Also, a restriction or a ban of a specific substance does not automatically mean that its replacements do not pose similar or other harm.
