Abstract
The widespread use of bisphenols in everyday life has led to their presence in various environment domain. Bisphenol A (BPA), commonly used as a monomer in producing polycarbonate plastics, epoxy resins, and flame retardants, is also known to act as an endocrine disruptor. This study aims to determine BPA concentrations in daily food-grade plastic containers and assess their toxicity in environmental samples contaminated by BPA leachates. The highest BPA concentration was detected in black poly bags (42.78 ppm), followed by slice juice bottles and infant milk bottles. Toxicity tests revealed significant effects on Rhizobium and Chlorella sp., representing soil and aquatic environments. Two potential bacterial strains, Brucella sp. and Brevibacillus parabrevis, were isolated from a landfill site to biodegrade BPA. Qualitative and quantitative analysis of biodegraded BPA using U-HPLC and GC-MS/MS identified various BPA metabolites. The results suggest that these native bacterial isolates could serve as promising candidates for BPA degradation, converting the contaminant into a less toxic and hazardous form. The study also highlights the risks associated with food-grade plastic containers and emphasizes the need for sustainable plastic waste management strategies.
