Bioconcentrations of 'Forever Chemicals'

 

As one goes up a food chain, concentrations of  pollutants in tissues and organs, increase. PFASs (so-called 'forever chemicals') are no exception. Some 'top predator' forms of wildlife, have many times the 'safe' concentrations of these persistent, synthetic chemicals in their bodies. Species especially impacted include dolphins, otters and porpoises. Fish are loaded with 'forever chemicals'. PFASs (used in many industrial processes) have been linked to cancers, immunological impairments and to infertility. Humans are also now clearly at risk as 'forever chemicals' are found in most surveyed drinking water (https://www.theguardian.com/environment/2025/jan/17/otters-among-uk-wildlife-carrying-toxic-forever-chemicals-analysis-shows). The potential health risks posed by PFASs have been known for decades. It's only recently that some countries have moved to restrict their spread. As , however, 'forever chemicals' are not broken down in the environment, their use in any part of the globe will be transmitted. Rainwater samples, taken from across the Earth, all contain PFASs
