Pesticide mixtures in soil: a global outlook

This data set includes four global maps of aggregated pesticides: (1) the total pesticide content in the topsoil of global croplands expressed in the unit of mg/kg-soil; (2) the number of pesticides detected in the topsoil; (3) the pesticide leaching rate to below the root zone expressed in the unit of mg/m2/year; and (4) the number of pesticides that exceeded a leaching rate of 1 mg/m2/year. This data set also includes two zip folders containing the topsoil residue and leaching rate of individual pesticide substances in nine different cropping systems. The surface area of the nine cropping systems can be obtained from the PEST-CHEMGRIDS dataset (Maggi et al., 2019). A zip folder containing an example of input files required to run the model is attached together with this data set. Details of the methods used to produce these maps and the tabulated data can be found in Tang F.H.M and Maggi F. (2021). Pesticide mixtures in soil: a global outlook, Environmental Research Letters.

本数据集包含四张全球汇总农药分布图：(1) 全球农田表层土壤中的农药总含量，单位为mg/kg-土壤；(2) 表层土壤中检出的农药种类数；(3) 农药向根区以下土层的淋溶速率，单位为mg/m²/年；(4) 淋溶速率超过1 mg/m²/年的农药种类数。本数据集还包含两个压缩文件夹，分别收录9种不同种植系统下单一农药物质的表层土壤残留量与淋溶速率数据。上述9种种植系统的地表面积可从PEST-CHEMGRIDS数据集（Maggi等，2019）获取。本数据集同步附带一个压缩文件夹，内含运行该模型所需的输入文件示例。有关生成上述分布图与列表数据的方法细节，可参阅Tang F.H.M与Maggi F.于2021年发表在《Environmental Research Letters》的论文《Pesticide mixtures in soil: a global outlook》。
