Data for: Assessment of cryogenic pretreatment for simulating environmental weathering in the formation of surrogate micro- and nanoplastics from agricultural mulch film

The dataset was collected using scanning electron microscopy, dynamic light scattering, thermogravimetric analysis, and the ASTM D5988 standardized test for measuring the biodegradability of plastics under ambient soil conditions. JMP software was used to prepare ta model curve fit to the size distribution data for nanoplastics. Data have not been processed beyond what was provided by the instrumenton, except for the size of microplastics, which was determined from electron micrographs using ImageJ software.

本数据集通过扫描电子显微镜（Scanning Electron Microscopy）、动态光散射、热重分析，以及ASTM D5988标准测试方法采集所得，该标准用于测定环境土壤条件下塑料的生物降解性能。研究人员使用JMP软件对纳米塑料的粒径分布数据进行拟合，生成对应的模型曲线。除通过ImageJ软件从电子显微图像中分析得到的微塑料尺寸数据外，其余数据均未进行仪器原始输出之外的额外处理。
