摘要

Environmental pollutants known as EDCs are present in drinking water, food, consumer goods, and the atmosphere and pose serious threats to ecosystems and human health. These pollutants come from industrial processes, wastewater discharge, and the usage of consumer products. They include hormones, per- and polyfluoroalkyl substances (PFAS), bisphenol A (BPA), phthalates, polycyclic aromatic hydrocarbons (PAHs), and pesticides. This study examines the global occurrence, sources, and fate of EDCs and evaluates the regulatory frameworks. Excess hormone levels are found in waters in Africa and Europe, and Africa suffers from higher contamination levels due to inadequate wastewater treatment. PFAS exceed regulatory standards in Europe, the Americas, and Asia, while BPA and phthalates persist in bottled water, rivers, and food, raising concerns over human exposure. The USA uses TSCA and EDSP, but loopholes such as the GRAS exemption under the FD&C Act permit unregulated EDC use. The EU uses a precautionary strategy, incorporating EDC legislation into REACH, the Plant Protection Products Regulation, and BPR. Asia, Africa, and Oceania exhibit mixed regulatory strategies, with some countries having strict bans, while others use risk-based strategies.
