摘 要: | Small-scale mercury smelting activities with indigenous method are always extensive in the Wuchuan area, northeastern Guizhou Province, China. Because of the simple processes without any environmental protection, a large amount of mercury vapor released to the ambient air during the processing of cinnabar roasting. So the health of the workers may be negatively affected through inhalation of the mercury-polluted air. Mercury, creatinine and β2-MG contents in urine among the workers in the study areas and the residents in the control site (Changshun County) were determined to discuss the health impact of mercury vapor exposure to the workers in the study areas. Health examinations also were carded out to identify clinical symptoms of mercury poisoning for the smelting workers. Results indicated that the geometric mean value of urinary mercury for the smelting workers was g/g Cr μg/g Cr (N=22), significantly higher than 1.24 μg/g (N=54) for residents in the control site. β2-MG as a renal biomarker can be used to study human nephrotoxicity at an early stage and it is most useful to define effects for assessing re-absorption function to indicate tubular injury. The results showed a serious adverse effect on renal system for the smelting workers due to mercury exposure. Several workers have already manifested some clinical symptoms of lightly chronic mercury poisoning and the symptoms include finger and eyelid lightly tremor, gingivitis and blue mercury line in mouth. The study illuminated that the workers in gaged in indigenous mercury smelting in the Wuchuan area were seriously exposed to mercury vapor,
