Field dissipation of four personal care products in biosolids‐amended soils in North China

0
The present study investigated the dissipation behaviors of these four typical personal care products (PCPs), triclocarban (TCC), triclosan (TCS), tonalide (AHTN) and galaxolide (HHCB), in biosolids‐amended soils under field conditions in North China. The results showed that the four target compounds were detected in all biosolids‐amended soils at a few to thousands ng/g levels (dry weight). The residual concentrations of the four PCPs were in the following order: TCC > TCS > AHTN >HHCB. Significant dissipation of the four PCPs was observed in the biosolids‐amended soils, with their half‐lives ranging from 26‐133 days. Furthermore, repeated biosolids applications and higher biosolids application rate could lead to higher accumulation of the four PCPs in the agricultural soils. Based on the detected concentrations in the field trial and limited ecotoxicity data, high risks to soil organisms would be expected for TCC, while low‐medium risks in most cases for AHTN and HHCB as well as for TCS.
