Extended Data Fig. 2: Effects of soil properties on cadmium concentrations in soil solution under the business as usual (BAU) scenario.

(a) Relationship between cadmium concentrations in soil solution against soil pH. (b) Relationship between cadmium leaching rate and soil pH. Each point represents an individual plot in one year in the BAU scenario, with scatter reflecting variation in soil clay contents and soil organic carbon (SOC) contents.
