What Are Persistent Organic Pollutants?

POPs are toxic synthetic substances composed of organic (carbon-based) chemical compounds and mixtures. They include industrial chemicals like PCBs and pesticides like DDT. They are primarily products and by-products from industrial processes, chemical manufacturing and resulting wastes.

Stockholm Convention on Persistent Organic Pollutants http://www.pops.int/TheConvention/ThePOPs/tabid/673/Default.aspx

Why are they a threat?

They are everywhere Arctic environment https://pubmed.ncbi.nlm.nih.gov/20493516/ (Remote Alaskans’ bodies https://pubmed.ncbi.nlm.nih.gov/28818814/)

They are toxic https://www.atsdr.cdc.gov/toxprofiles/tp200.pdf

They are persistent https://oem.bmj.com/content/75/1/46

They accumulate in body fat and cause things like dementia

They transfer to the fetus and in breast milk and baby food https://pubmed.ncbi.nlm.nih.gov/20494442/

They travel the globe on wind and water currents

Amounts are increasing of flame retardants https://www.epa.gov/great-lakes-monitoring/great-lakes-integrated-atmospheric-deposition-network-trends-and-changes#pcb while PCB, OCP and PAH all are decreasing (Clean Air Act) which SCOTUS just restricted (https://www.supremecourt.gov/opinions/21pdf/20-1530_n758.pdf) because … job creators -don’tcha know?

How do they cause damage?

They are hormone disruptors. They cause miscommunication in very small doses, just like hormones. Testosterone is a controlled substance because of its power to disrupt. Fetal exposures are especially dangerous because they can cause developmental abnormalities and cause damage to cognitive, reproductive and immune functions.

Centers for Disease Control and Prevention found that exposure to PFAS caused a whole host of health issues including increased rates of liver and heart disease, decreased antibody responses to vaccines, cancer, low birth weight in babies, and thyroid problems. https://www.atsdr.cdc.gov/toxprofiles/tp200.pdf

Where are they found and how am I exposed?

What can I do about my exposure?

Water filter at home. Dual stage filter with carbon block or reverse osmosis were both highly effective at eliminating nearly all PFAS https://pubs.acs.org/doi/10.1021/acs.estlett.0c00004#
