镉可以对肾、肺、肝、睾丸、前列腺发生作用。肾被认为是最先受到作用的靶器官,而且肾功能的生物学监护已被推荐来帮助保持镉作业工人的健康。本文报导一个按触镉九年的工人无旦白尿而伴有血镉和尿镉浓度增高以及尿中β_2一微球旦白的排泄增加,这就提出了在镉作业工人的有效监护上,生物学指标将证明是最有用的。 Cadmium can kidney, lung, liver, testis, prostate role. Kidneys are considered the first target organ to be affected, and biological monitoring of renal function has been suggested to help maintain the health of cadmium workers. This paper reports a nine-year cadmium-exposed workers with no albuminuria accompanied by elevated concentrations of blood cadmium and urine cadmium and urinary excretion of β 2 -microglobulin increased, which proposed the effective monitoring of cadmium workers, Biological indicators will prove to be the most useful.
