Main occupational hazard and its health effects in a copper smelter

[Objective]To understand the type of occupational hazards and its effect on health of workers in the workshop of copper smelting plant so as to find out the occupational hazards control point.[Methods]Field occupational health survey and occupational hazards monitoring in work place were adopted to analyze the occupational hazards.Biological sample detection method was used to detect blood lead,blood cadmium,urine arsenic concentrations.And the data were analyzed by SPSS 16.0 and Excel 2003.[Results] Heavy metal(copper,lead,cadmium,arsenic) were the main hazards in the melt shop,SO2 was detected in many work shop,The qualified rate of copper,cadmium,lead,arsenic,SO2 were 100%,97.2%,76.4%,70.8%,98.6% The level of blood cadmium,blood lead,urine arsenic was not apparently correlated with overall age or service length(P0.05).[Conclusion]Flash smelting is a critical control point to occupational hazards in the whole smelting process.And anode slime pit is the very important control point to arsine in potroom.Cumulative effect of lead and urine is not obvious in the body of workers.
