Abstract: Lead is not a necessary element to crop growth but a pollutant with accumulation problems. If lead is absorbed by soil, it will be difficult to be removed. Polluted soil will result in toxin in agricultural product and lead can enter into food chain by soil-crop system, which will hurt human beings. This paper summarized the source of lead, accumulation and migration in agricultural soil-crop system in order to remind people to pay attention to the harm of lead and prevent it early.
