The study examines the concentrations of heavy metals in agricultural soil, compost from landfills, maize plants, and spinach crops. The results show that compost from landfills had levels exceeding EU requirements for Cd, Cu, Ni, Pb, and Zn. However, agricultural soil contained trace amounts of heavy metals. The order of metal absorption by plants was Cd > Pb > Cu > Ni > Cr > Zn > Fe > Mn. This highlights potential health risks associated with consuming crops grown in compost or soil tainted with heavy metals.
该研究检测了农业土壤、垃圾填埋场堆肥、玉米植株和菠菜作物中的重金属浓度。结果表明，垃圾填埋场堆肥中的镉、铜、镍、铅和锌含量超过了欧盟的要求。然而，农业土壤中含有微量重金属。植物对金属的吸收顺序为镉＞铅＞铜＞镍＞铬＞锌＞铁＞锰。这突出了食用在受重金属污染的堆肥或土壤中种植的作物所带来的潜在健康风险。
