Abstract

Accompanied by urbanization and industrial development, the introduction of fertilizers, pesticides, and waste materials into the soil and water has resulted in heavy metal pollution of arable land and water sources, posing a serious threat to food and agricultural product safety, and bringing significant potential harm to human health. This paper focuses on central Jilin (Changchun, Siping, and Songyuan) as the study area, with primary research on the total-effective-plant seed content of heavy metals and their transformation and accumulation, in conjunction with land use data. It explores the constraints of heavy metal pollution in arable soil and the efficiency of its transformation and accumulation in relation to arable land use in the black soil region, aiming to provide a theoretical basis for the sustainable use of arable resources in the context of rapid urbanization in black soil areas.
