Abstract:
The present study investigated the dissipation behaviors of 4 typical personal care products (PCPs)—triclocarban (TCC), triclosan (TCS), tonalide (AHTN), and galaxolide (HHCB)— in soils amended with biosolids under field conditions in North China. The results showed that the 4 target compounds were detected in all biosolids‐amended soils at levels of a few nanograms per gram to thousands of nanograms per gram (dry wt). The residual concentrations of the 4 PCPs were found in the following order: TCC 〉 TCS 〉 AHTN 〉 HHCB. Significant dissipation of the 4 PCPs was observed in the biosolids‐amended soils, with half‐lives ranging from 26 d to 133 d. Furthermore, repeated biosolids applications and a higher biosolids application rate could lead to higher accumulation of the 4 PCPs in the agricultural soils. Based on the detected concentrations in the field trial and limited ecotoxicity data, high risks to soil organisms are expected for TCC, whereas low to medium risks are expected in most cases for AHTN, HHCB, and TCS.
