重金属污染：土壤安全与农产品质量的严峻挑战

In recent decades, with the rapid development of science and technology, mining, smelting, industrial production, and the improper use of fertilizers in agriculture have caused serious heavy metal pollution. As a result, the quality and safety of soil have become increasingly critical. Agricultural soil is an essential natural resource for humans. Once agricultural soil is contaminated by heavy metals, it requires significant time and money to restore. Furthermore, it can lead to the presence of heavy metals in agricultural products, which may affect human health through the food chain.
