Quantifying source-specific intake risks of wheat cadmium by associating source contributions of soil cadmium with human health risk

Sources of cadmium (Cd) contamination of farmlands and the potential risk to human health via dietary intake of wheat Cd are of great concern to consumers. A source-specific risk assessment (SSRA) model, which combined a positive matrix factorization receptor model and spatial analysis with a health...
