Abstract:
... Bisphenol-B (BPB), an analogue of bisphenol-A is used in the plastic industry. It has been found to leach from plastic containers leading to its contamination in canned food products. Moreover, it has also been detected in human samples such as sera and urine. BPB is recognized as a potential endocrine disrupting chemical owing to its estrogenic and anti-androgenic nature. Therefore, it was pertin ...
