Abstract
Bisphenol A (BPA) raises concerns among the scientific community as it is one of the most widely used compounds in industrial processes and a component of polycarbonate plastics and epoxy resins. In this review, we discuss the mechanism of BPA toxicity in food-grade plastics. Owing to its proliferation in the aqueous environment, we delved into the performance of various biological, physical, and chemical techniques for its remediation. Detailed mechanistic insights into these removal processes are provided. The toxic effects of BPA unravel as changes at the cellular level in the brain, which can result in learning difficulties, increased aggressiveness, hyperactivity, endocrine disorders, reduced fertility, and increased risk of dependence on illicit substances. Bacterial decomposition of BPA leads to new intermediates and products with lower toxicity. Processes such as membrane filtration, adsorption, coagulation, ozonation, and photocatalysis have also been shown to be efficient in aqueous-phase degradation. The breakdown mechanism of these processes is also discussed. The review demonstrates that high removal efficiency is usually achieved at the expense of high throughput. For the scalable application of BPA degradation technologies, removal efficiency needs to remain high at high throughput. We propose the need for process intensification using an integrated combination of these processes, which can solve multiple associated performance challenges.
双酚 A(BPA)引起了科学界的关注,因为它是工业生产中使用最广泛的化合物之一,也是聚碳酸酯塑料和环氧树脂的成分之一。在本综述中,我们将讨论食品级塑料中双酚 A 的毒性机理。由于双酚 A 在水环境中的扩散,我们深入研究了各种生物、物理和化学技术对其进行修复的性能。我们对这些去除过程进行了详细的机理研究。双酚 A 的毒性作用表现为大脑细胞层的变化,可导致学习困难、攻击性增强、多动、内分泌失调、生育能力下降以及对非法物质依赖的风险增加。细菌分解双酚 A 会产生毒性较低的新中间体和产品。膜过滤、吸附、混凝、臭氧和光催化等过程在水相降解中也被证明是有效的。此外,还讨论了这些过程的分解机制。综述表明,高去除效率通常是以牺牲高通量为代价的。为了实现双酚 A 降解技术的规模化应用,需要在高产能的情况下保持高去除效率。我们提出需要利用这些工艺的综合组合来强化工艺,从而解决多个相关的性能挑战。
