Abstract:

Bisphenol A (BPA) is the man-made organic compound which is an important polymer used for the manufacturing of plasticizers, polycarbonates and epoxy resins. Plastic waste is increased in our environment due to its increasing demand day by day. Bisphenol A also known as an endocrine disruptor which mimics female sex hormone estrogen. Bisphenol A is acting as hormones so can induce cellular reactions and changes at very lower concentration. Thus determination of the concentration of BPA, its toxicity on soil environment and its degradation methods is of research interest. The developed method during this research project helps to determine the level of exposure and its toxicity and degradation methods. The 9 plastics items were analysed using UV/VIS spectrophotometer, all of them have significant amount of Bispehnol A present, the highest concentration of BPA was observed in Black polybags with 42.78 ppm followed by slice juice bottle (42.11 ppm) then baby bottle with 38.56 ppm. Here, we also investigated the toxicity of BPA on soil microflora by evaluating the CFU/ml. Adverse effect of BPA seen on microbial colonies number, the control plates CFU/ ml was observed TNTC (Too numerous to count) while as the BPA concentration of 250 ppm and 500 ppm applied to culture the significant reduction in growth is observed respectively, 9 x 106 CFU/ml in 250 ppm BPA treated plate and 1.2 x 106 CFU/ml in 500 ppm BPA treated plate. For the determination of Rhizobium activity, a clear zone of inhibition was observed around discs and wells poured with 500 ppm BPA. The significant impact of BPA was also seen on Phosphate solubilizing bacteria (PSB). The present study is being extrapolated to see the effect of bacterial treatment in degrading BPA in lab scale experiments and results were analysed through HPLC.
