Because of its toxicity and impacts on the environment and human health, bisphenol A (BPA) has been controlled in numerous industrialized nations, increasing demand for bisphenol analogues (BP) for its replacement. However, the consequences of these chemicals on the environment and the health of persons exposed to their emissions are still being researched. The emissions from polypropylene manufacturing facilities in Colombia and Brazil were evaluated in this study, and the presence of bisphenol A and four BPs was detected among the gaseous compounds released, with total concentrations of BPs (∑BP) between 92 and 1565 ng g. As the melt flow index (MFI) of the polymer rises, so does the quantity of volatiles in its matrix that are eliminated during deodorization, indicating that the MFI and the amount of bisphenol released have a directly proportional connection.
由于双酚 A（BPA）的毒性及其对环境和人类健康的影响，许多工业化国家已经对其加以控制，从而增加了对其替代品双酚类似物（BP）的需求。然而，这些化学物质对环境和接触其排放物的人的健康的影响仍在研究之中。本研究评估了哥伦比亚和巴西的聚丙烯制造设施的排放情况，并在释放的气态化合物中检测到了双酚 A 和四种 BP，总 BP 浓度（∑BP）在 92 至 1565ng/g 之间。随着聚合物熔体流动指数（MFI）的升高，在脱臭过程中从其基质中消除的挥发性物质的数量也会增加，这表明 MFI 和释放的双酚 A 之间存在直接的比例关系。
