Solution Summary
This solution discusses in detail the reasons why Perfluorooctane Sulphonate (PFOS) is very much resistant to processes such as hydrolysis, photolysis, and aerobic and anaerobic biodegradation. The structure of PFOS is given as well as its chemical properties, which explain why it is one of the persistent environmental pollutants.
Solution Preview
PFOS is a contaminant that is found almost everywhere in the environment. This substance can serve as an ingredient in fire extinguishing foams, wrappers for microwave ovens and numerous products (including food!). This ubiquitous pollutant was also discovered in different aquatic animals such as dolphins, seals, otters and even polar bears.
"PFOS accumulates to a high degree ...
