摘　　要：目的　了解某铅锌矿及周围镉污染区镉接触者的健康状况 ,为镉污染所致慢性镉中毒症的判定提供依据。方法　对骨密度测定值低于 X -S的 84例研究对象进行尿样检测和分析 ,并对其中骨密度测定值低于 X - 2S的 2 2例研究对象进行骨骼X线检查。结果　尿镉、尿NAG、尿 β2 -MG分别为14 48μg/g.cr、14 46U/g .cr、40 4 5 9μg/g.cr;尿镉≥ 15 μg/g .cr时 ,尿NAG和尿β2 -MG出现显著升高 ,且超过正常人群中的参考值 ;2 2例研究对象的X线拍片结果显示 ,有 19例有不同程度的骨质疏松或骨质软化。结论　用尿镉≥ 15 μg/g .cr作为环境镉污染致慢性镉中毒中晚期病例的判定条件之一是可行的。Objective To investigate the health status of cadmium-exposed population in a Lead-Zinc mine and its cadmium-polluted area so as to provide infomation for discrimination of chronic cadmium poisoning caused by environmental pollution.Methods The urine samples of 84 cases whose bone density was less than -S were collected and 22 cases whose bone density was less than -2S were examined by X ray further more.Results Urine Cadmium,NAG,β 2-MG were 14.48μg/g.cr,14.46U/g.cr and 404.59μg/g.cr respectively.Ninteen cases suffered from osteoporosis and/or osteomalacia in variety degree.Conclusion It was practicable that urinary cadmium more than 15μg/g.cr was used to discriminate the late-stage cases of chronic cadmium poisoning caused by environmental pollution.
