Compiled dataset on soil cadmium bioaccessibility, related properties, and concentration across China

## OverviewThis dataset supports the research presented in the manuscript titled "Development of a Soil Cadmium Bioaccessibility Prediction Model and Its Applications in Environmental Health Risk Assessment". It systematically compiles multi-source data related to soil cadmium (Cd) pollution, bioaccessibility, and health risk assessment across China. ## File ContentThe dataset is provided as a single Excel file (.xlsx) containing the following worksheets: Original_Data: Original data points extracted from published literature, including total soil Cd concentration, in vitro gastrointestinal bioaccessible Cd content, and associated soil physicochemical properties (e.g., pH, organic matter, texture, iron content). Processed_Data: Cleaned and imputed data for modeling. Soil_Properties: Descriptive statistics and spatial distribution characteristics of soil properties (e.g., pH, organic matter, clay, sand content) for major geographical regions of China. Cd_Content_Data: Soil cadmium concentration data and their statistical summaries (e.g., geometric mean, mean) for each province across China, obtained through a systematic literature review. Cd_Source: The complete references and sources corresponding to the provincial Cd concentration data listed in Cd_Content_Data.
