摘要： The environmental contamination of ultraviolet absorbents (UVAs) has attracted global attention for the persistence, bioaccumulation and ecotoxicity. However, little is known about the content and distribution characteristics of UVAs in agricultural soils, especially in facility agricultural soils. In this study, the contents and distribution characteristics of 16 UVAs were surveyed in agricultural facility soils (N = 61) and field soil samples (N = 61) from 27 provinces in China. The total content of 16 UVAs (Sigma 16UVAs) in facility soils (mean 64.2 +/- 55.4 ng/g) was higher than that in field soils (mean 9.66 +/- 7.66 ng/g), suggesting that UVAs in facility soils are associated with mulch film. The Sigma 16UVAs content in the soil mulched with biodegradable (PBAT) film was higher than that in the soil mulched with polyethylene (PE) film, which indicated that the UVA pollution in the soil mulched with biodegradable film was more serious. With the continuous promotion of the use of biodegradable films may pose a threat to soil and ecological health. Therefore, studies on the content and distribution characteristics of UVAs in facility soils are needed to provide scientific basis for the controlling and monitoring of novel pollutants.
