Soil Antibiotic Pollution and Ecological Risk Assessment in the Pearl River Delta Region, China.

ABSTRACT: Excessive antibiotic use and their release into soils leads to alterations in soil processes, adversely affecting terrestrial organisms and presenting a serious threat to crop growth and productivity. Herein, the spatial patterns and prevalence of 22 typical antibiotics in agricultural soils throughout the Pearl River Delta area of China. In addition, the contamination characteristics and health risks were evaluated by integrating ArcGIS 10.7 spatial analysis, spearman correlation, and Risk Quotient (RQ) modeling. Antibiotics were detected in all the 240 soil samples with the total concentrations ranging from ND to 897 μg·kg^-1 dry weight. The concentrations of seven antibiotic classes followed the order: quinolones (21.0 μg/kg) > β-lactams (15.1 μg/kg) > tetracyclines (9.65 μg/k
