Renal Damage in Cadmium Exposed Residents in Cadmium Polluted Areas / 环境与健康杂志

ABSTRACT

Objective To know the renal damage in cadmium (Cd) exposed residents in Cd polluted areas where polluted by Cd for 20 years. Methods The levels of urinary Cd (UCd), N-acetyl-beta-D-glucosaminidase (UNAG), ?2-microglobulin (UBMG), retinal binding protein (URBP), and albumin (UALB) were measured in 39, 65, 57, and 42 residents lived in the severe-, moderate-, light-, and non-polluted area respectively for more than 20 years. The test indexes were adjusted with urinary creatinine, and geometric means were statistically used. Results The levels of UCd in all subjects were obviously decreased compared with those in 1992, but the levels of UCd, UNAG, UBMG, and URBP and the abnormal rate of UNAG in residents in Cd-polluted areas were significantly higher than those in residents in non-polluted area (P
