陶瓷厂和钨矿生产性粉尘中11种元素比较分析

Comparison of element content of reproductive dust in pottery factories and tungsten mines.

目的探讨陶瓷厂和钨矿生产性粉尘中多种元素含量的差异以及其对粉尘毒性和致病作用的可能影响。方法收集厂矿粉尘各50 g,用火焰原子吸收光谱法检测陶瓷厂和钨矿粉尘样品中铜、锌、铅、镉、镍、铁、锰、钙、镁9种元素的含量,用石墨炉原子吸收光谱法检测样品中铝元素的含量,用原子荧光光谱法检测样品中砷元素的含量。结果陶瓷厂和钨矿粉尘样品中铝、砷、镉、铁、锰、铅元素含量的差异有统计学意义(P<0.05),陶瓷厂粉尘中铝元素的平均含量为104 688.71μg/g,大于钨矿粉尘中的平均含量64 883.17μg/g;陶瓷厂粉尘中砷、镉、铁、锰、铅元素的平均含量分别为31.04、2.27、4 473.23、369.67、96.86μg/g,而钨矿的分别为80.32、20.64、28 619.06、1 596.93、333.02μg/g,均高于陶瓷厂。结论陶瓷厂和钨矿粉尘中多种元素的含量有明显的差异,元素含量的不同,可能会影响粉尘的生物学效应活性,对粉尘的致病作用有一定的影响。

Objective To compare the element content of reproductive dusts in pottery, factories and tungsten mines and to evaluate the potential role of elements on toxicity and pathogenicity of dusts. Methods The total of 50 g settied dusts were collected in the target mine or factory. Nine elements,such as Cu,Zn,Pb, Cd, Ni, Fe, Mn, Ca and Mg, were detected by flamed atomic absorption spectrometry, AI and As detected by black lead stove atomic absorption spectromcuy and atomic fluorescence spectrometry respectively. Results The average doses of Al, As, Cd, Fe, Mn, and Pb were different in reproductive dusts of pottery factories and tungsten mines. The average content of AI element in pottery collected dusts was 104 688.71 μg/g, higher than that in tungsten dusts. The average content of As, Cd, Fe, Mn, Pb elements in pottery collected dusts was 31.04,2.27,4 473.23,369. 67.96. 86 μg/g respectively, which were higher in comparison with those in tungsten dusts,namely 80. 32,20. 64,28 619.06,1 596.93,333.02 μg/g. Conclusion Conclusion Element content in reproductive dusts in pottery factories were significantly different from that in tungsten mines. The results of element content may be helpful for understanding the different influence of silicosis and biological effect of dust particles.
