Description: In the last decade, the occurrence of bisphenol in the environmental compartments has raised lots of concern. Being an endocrine compound, bisphenol has the ability to cause harmful effects to aquatic life. Bisphenol was widely detected in the surface water. Therefore, there is a need to evaluate the potential risk of the presence of bisphenol in crops irrigated with wastewater. Therefore, this study was conducted to (1) investigate the fate and transport of bisphenol A, F and S in potato tubers in soil irrigated with synthetic wastewater, (2) examine the effect of plantain peel biochar as a soil amendment on reducing the concentrations of bisphenol in soil and potato. A field lysimeter study for two seasons was conducted to investigate the abovementioned goals. Results showed that none of the tested bisphenols was found in the flesh of potato tubers after harvest in both seasons. In the first season, the concentration of bisphenols in topsoil increased over the four months study, indicating the cumulative effect in the topsoil. However, this trend was reversed in the second season, indicating a decline in bisphenol removal efficiency. It is assumed that growing crops could have promoted the microbial community in soil. Therefore, the degradation rate of bisphenol on topsoil could be increased subsequently. More studies are needed to further investigate the effect of biochar on bisphenol fate in soils.
