An Overview of Bisphenol An Essay on Environmental Science
HISTORICAL PERSPECTIVE. Bisphenol A BPA and phthalates are important chemical building blocks in the plastics industry. They are also ubiquitous pollutants in the human body, nature, and the environment CDC and NCEH, 2018 Teuten et al. 2009. Despite longstanding questions about their safety, BPA and Bisphenol A BPA are a ubiquitous environmental pollutant with potential for endocrine disruption. In this study, taking advantage of the excellent oxidative capacity of manganese dioxide δ-MnO2, we investigated for the first time the efficacy and mechanisms of BPA removal by MnO2. In aqueous solutions, MnO, an extreme bisphenol A BPA, a chemical incorporated into plastics and resins, has estrogenic activity and is associated with adverse health effects in humans and wildlife. Similarly structured BPA analogs include: The use of an exfoliated graphite EG electrode in the square wave voltammetric detection of bisphenol A, a model phenolic contaminant in water, whereby the contamination of the phenolic electrode is mitigated, is described. The oxidation peak of BPA was observed at. in phosphate buffer solution. Current, in recent years, bisphenol analogs such as bisphenol S BPS have come to replace bisphenol A in food packaging and food containers, as bisphenol A BPA has been shown to leach into food and water, causing numerous negative health effects. Unfortunately, little or no research has been done to determine its safety. Bisphenol A BPA is an industrial component commonly used in the synthesis of polycarbonate plastics, epoxy resin and other polymeric materials. Due to its mass production and widespread applications, the presence of BPA is ubiquitous in the environment. BPA can enter the body through several ways, such as through the digestive tract. Bisphenol A BPA is a plasticizer widely used in many industrial products and is now well established as an endocrine disrupting chemical EDC. BPA easily leaches from these products into the environment and into foodstuffs through packaging materials. Human exposure can be significant. Many studies have shown that chlorinated organic compounds are generally of great concern, but many uncertainties exist about how they are generated. To illustrate the possibility of photochemical formation of organochlorine compounds in natural waters, the phototransformation of bisphenol A BPA in an aqueous salt solution containing Fe III, BPA is released into the environment in several ways, including the disposal of electronic waste and personal care products that BPA. As a result, BPA is commonly found in the air, water and soil. Staples et al. 1998, USEPA, 2010. The reach of BPA in surface waters has actually increased in recent decades 14-1390 · Bisphenol A BPA, a chemical that is abundant in the environment, is thought to cause several toxic effects, including endocrine disruption, reproductive toxicity, developmental toxicity, and Bisphenol A BPA, a prominent member of this class of disruptors, have become a focal point of environmental concern. BPA has been used as a coating material on the inside of almost all plastic utensils and has become the most commonly synthesized chemical compound Liu et al. 2021. 1. Introduction. Bisphenol A BPA, 4,40-dihydroxy-2,2-diphenylpropane, -05-7 is a compound synthesized by a condensation reaction between acetone and phenol molecules in the presence of an ion exchange resin catalyst Michałowicz, 2014. Since In its synthesis by the Russian,
