2026-09-18 Article“Spatial distribution and ecological-health risks associated with herbicides in soils and crop kernels of the black soil region in China”（new） doi:10.57760/sciencedb.iga.001gn en This thesis conducts a comprehensive study on the herbicides in the soil and crop seeds of the black soil region. In terms of basic composition, it systematically investigated 29 types of target herbicides that are widely used in the farmlands of the black soil area in China. The specific parameters include their residual concentrations in the soil and the seeds of corn, soybeans, and rice, the detection frequency, spatial distribution, as well as the ecological and health risk values calculated based on risk quotient, toxicity unit, and carcinogenic/non-carcinogenic risk models. This research covers the spatial area of Hailun City in Heilongjiang Province (a typical black soil region), the crop types of the region's main food crops (corn, soybeans, and rice), and the types of herbicides used in a mixed manner. This study can provide a reference for researchers studying the process of herbicide pollution and mitigation techniques in some parts of the black soil region in Northeast China, and also provide data support for subsequent studies on the migration and mitigation of herbicides in farmlands.
