镉(Cd)是一种能导致环境污染的物质,它危害人类的主要途径是通过对土壤和水质的污染而污染食物链。土壤中Cd离子的活度,直接影响植物对Cd的吸收,但它又取决于土壤或胶体对Cd的吸附与解吸。而土壤或胶体对Cd离子的吸附和解吸却受控于土壤中粘
Cadmium (Cd) is a substance that can cause environmental pollution. Its main way of endangering mankind is to pollute the food chain through pollution of soil and water quality. The activity of Cd in soil directly affects the absorption of Cd by plants, but it depends on the adsorption and desorption of Cd by soil or colloid. The soil or colloids on the adsorption and desorption of Cd ions are controlled by the soil sticky
