Data for: Wetland soil microplastics are negatively related to vegetation cover and stem density

These are data on microplastics numbers and mass in sediments in 6 plots in each of 4 habitats from a restored tidal freshwater wetland in Washington, DC. The dataset also includes data on plot cover of vegetation and soil bulk density and organic matter content.本数据集源自美国华盛顿特区一处修复后的潮汐淡水湿地，包含该湿地4类生境各6个样地的沉积物中微塑料（microplastics）的数量与质量数据。此外，数据集还涵盖各植被样地盖度、土壤容重及有机质含量的相关测定数据。
