Article“Legacy of herbicides in water from Hailun City, Northeast China: Occurrence, source, and ecological risk assessment”（new）

The basic composition consisted of 15 target herbicides, including chloroacetamide type, triazine type, ketone type, sulfonylurea type and chlorophenoxyacetic acid type. Specific parameters included their concentrations in surface water and groundwater, detection frequency, as well as ecological risk values based on risk quotient, toxicity unit and risk index models.

The data format was quantitative concentration data determined by chromatography-mass spectrometry coupling. The data accuracy was controlled through method detection limit, spiked recovery rate and relative standard deviation. In terms of data coverage, this study covered a typical black soil area in Hailun City, Heilongjiang Province, China.
