Abstract: Under the pressure of water scarcity, municipal treated wastewater is increasingly used for agricultural irrigation in the world. However, treated wastewater contains numerous so-called contaminants of emerging concern (CECs), including bisphenols, steroids, and pharmaceutical and personal care products. When treated wastewater is used to irrigate food crops, some CECs may accumulate and pose health risks. We have carried out laboratory, greenhouse and field studies to evaluate the fate of CECs in soil and uptake of common CECs into vegetables. This presentation will provide an overview on the occurrence of CECs in treated wastewater, adverse ecological effects of CECs, fate in soil, accumulation into plants, and potential risks.
