Every so often, something in the news of health concern shows up reminding me of the state of world-wide contamination with this stuff. Not sensationalized like immediate-concern problems, because there are few outward symptoms, except with the cancer-producers. It's the effect on the youngest people: kids, and future kids which is frightening to me. Unpublicized widespread testing overr the past 20 or 30 years, has quietly revealed nearly 100% of the human beings alive have detectable levels of such synthetic man-made chemicals residing in their bodies. "BPA is employed to make certain plastics and epoxy resins. BPA-based plastic is clear and tough, and is made into a variety of common consumer goods, such as water bottles, sports equipment, CDs, and DVDs. Epoxy resins containing BPA are used to line water pipes, as coatings on the inside of many food and beverage cans and in making thermal paper such as that used in sales rec In 2011, an estimated 10 billion pounds of BPA chemical were produced for manufacturing polycarbonate plastic, making it one of the highest volume of chemicals produced worldwide. BPA exhibits estrogen mimicking, hormone-like properties that raise concern about its suitability in some consumer products and food containers. Since 2008, several governments have investigated its safety, which prompted some retailers to withdraw polycarbonate products. The U.S. Food and Drug Administration (FDA) has ended its authorization of the use of BPA in baby bottles and infant formula packaging, based on market abandonment, not safety.[4] The European Union and Canada have banned BPA use in baby bottles." https://en.wikipedia.org/wiki/Bisphenol_A "The only North American producer, Monsanto Company, marketed PCBs under the trade name Aroclor from 1930 to 1977. One estimate (2006) suggested that 1 million tons of PCBs had been produced. 40% of this material was thought to remain in use.[1] Another estimate put the total global production of PCBs on the order of 1.5 million tons. The United States was the single largest producer with over 600,000 tons produced between 1930 and 1977. The European region follows with nearly 450,000 tons through 1984. It is unlikely that a full inventory of global PCB production will ever be accurately tallied, as there were factories in Poland, East Germany, and Austria that produced unknown amounts of PCBs In an electric arc, PCBs generate incombustible gases. Use of PCBs is commonly divided into closed and open applications.[1] Examples of closed applications include coolants and insulating fluids (transformer oil) for transformers and capacitors, such as those used in old fluorescent light ballasts,[22] hydraulic fluids, lubricating and cutting oils, etc. In contrast, the major open application of PCBs was in carbonless copy ("NCR") paper, which even nowadays results in paper contamination.[23] Other open applications were as plasticizers in paints and cements, stabilizing additives in flexible PVC coatings of electrical cables and electronic components, pesticide extenders, reactive flame retardants and sealants for caulking, adhesives, wood floor finishes, such as Fabulon and other products of Halowax in the U.S.,[24] de-dusting agents, waterproofing compounds, casting agents.[8] It was also used as a plasticizer in paints and especially "coal tars" that were used widely to coat water tanks, bridges and other infrastructure pieces. In general individuals are exposed to PCBs overwhelmingly through food, much less so by breathing contaminated air, and least by skin contact. Once exposed, some PCBs may change to other chemicals inside the body. These chemicals or unchanged PCBs can be excreted in feces or may remain in a person's body for years, with half lives estimated at 10–15 years. [30] PCBs collect in body fat and milk fat.[31] PCBs biomagnify up the food web and are present in fish and waterfowl of contaminated aquifers.[32] Infants are exposed to PCBs through breast milk or by intrauterine exposure through transplacental transfer of PCBs [31] and are at the top of the food chain PCBs have shown toxic and mutagenic effects by interfering with hormones in the body. PCBs, depending on the specific congener, have been shown to both inhibit and imitate estradiol, the main sex hormone in females. Imitation of the estrogen compound can feed estrogen-dependent breast cancer cells, and possibly cause other cancers, such as uterine or cervical. Inhibition of estradiol can lead to serious developmental problems for both males and females, including sexual, skeletal, and mental development issues.[citation needed][43] In a cross-sectional study, PCBs were found to be negatively associated with testosterone levels in adolescent boys. Other toxic effects such as endocrine disruption (notably blocking of thyroid system functioning) and neurotoxicity are known.[6] PCBs have entered the environment through both use and disposal. The environmental fate of PCBs is complex and global in scale" https://en.wikipedia.org/wiki/Polychlorinated_biphenyl My concern stems from the fact that much of what is known today, regarding these chemicals, was pretty well-known to their originators, as far back as the 1930s. Today, worldwide awareness exists regarding environmental destruction, and yet......China's largest cities have air alm,ost unbreatheable. Frank
