This week he discusses PCB. Read more below the video.
PCBs stand for Polychlorinated biphenyls. These are a group of man-made chemicals that were originally manufactured by Anniston Ordnance Company, in Anniston, Alabama back in 1927 and Monsanto ultimately was responsible for 99% of PCB manufacturing in the U.S. They were used as additives to many commercial and residential products including dielectric fluids (in transformers and electrical components) coatings, adhesives, caulking, and gaskets. Some coatings and caulking can contain upwards of 100,000ppm. Due to their toxicity to humans and the environment, they were banned by the EPA in 1979 under TSCA. They are PCBs are classified as probable human carcinogens and are listed in the top 10% of EPA’s most toxic chemicals. They cause a wide array of human health effects including affecting the nervous system, liver and kidney, reproductive system, respiratory illness (asthma), and developmental issues (there are more health effects than these)
