A review on environmental distributions and risk management of phenols pertaining to the endocrine disrupting chemicals in Taiwan

Abstract

Some phenols, including pentachlorophenol, dichlorophenol, alkylphenols (nonylphenol & octylphenol) and bisphenol-A, have been identified as endocrine disrupting chemicals (EDCs). These phenolic EDCs are extensively used in a wide range of household products, thus posing potential health risks for humans exposed to them. From the viewpoints of ecotoxicology, human health and regulations, it is urgent to restrict the emissions and releases of these estrogenic chemicals from the industrial processes and commercial products. This review article first focused on the physicochemical properties of phenolic EDCs and their industrial/commercial uses. Furthermore, their environmental distributions and regulatory frameworks for integrated risk management of these chemicals in Taiwan were conducted as a case study. Emphasis was thus put on the cross-ministerial joint venture (i.e., environment, health, agriculture, labor, and industry authorities), and the government policy on the risk management of EDCs. Finally, some recommendations for pollution prevention and toxicity reduction of phenolic EDCs were also addressed and analyzed to progress towards a sustainable society in Taiwan.
