铅、镉对人体健康的危害已有大量资料报导。长期低剂量暴露时,肾脏是其损害的主要靶器官之一,引起肾小管重吸收功能障碍,表现为尿中低分子蛋白质如溶菌酶(LYS)、β_2一微球蛋白(β_2—MG)、金属硫蛋白等排泄量增多。铅镉为共生金属,无论是采矿还是冶炼行业工人往往同时暴露于这两种金属中。虽然已有不少有关接触铅或镉致肾功能损
Lead, cadmium harm to human health has a lot of information reported. Long-term low-dose exposure, the kidney is one of the main target organ damage, causing tubular reabsorption dysfunction, manifested as urinary low-molecular proteins such as lysozyme (LYS), β_2-microglobulin (β_2-MG) Metallothionein and other excretion increased. Lead and cadmium are symbiotic metals, and workers in mining and smelting industries are often exposed to both metals simultaneously. Although there have been many related to lead or cadmium exposure to renal dysfunction
