Abstract
Objective To provide scientific evidences for preventing and controlling dust hazard understanding the status of dust hazard in building and sanitary ceramics enterprises.Methods 19 building and sanitary ceramics enterprises were hygienicly investigated.The dust concentration in their workplaces and the content of free silica of the dust were detected.Results The detection of 121 copies of dust deposition at the workplaces showed that the content of free SiO2 was (29 ±15.4)%,was (33.2±13.2)% in architectural ceramics enterprises,and was (28.9±13.0)% in sanitary ceramics enterprises,with no statistical difference between these two enterprises(P > 0.05).The dust's time weighted average concentration (total dust CTWA) ranged from 0.08 to 29.7 mg/m3,with a standard-exceeding rate of 19.6%(170/868) and a highest level 28.7 times the maximum occupation contact limiting value.Building ceramics enterprises' total dust CTwA exceeding standard rate (22.6%) was significantly higher than sanitary ceramicsenterprises'(8.5%),with a statistical difference(P < 0.001).The respirable dust CTWA ranged from 0.04 to 5.00 mg/m3,with a exceeding standard rate of 9.5% (77/811) and a highest level 6.1 times the occupation contact limiting value.Building ceramics enterprises' respirable dust CTWA exceeding standard rate (11.1%) was significantly higher than sanitary ceramics enterprises'(2.6%),with a statistical difference(P < 0.05).Conclusions The content of free SiO2 and the total dust and respirable dust CTWA exceeding standard rates are high in ceramic dust,which is harmful to the health of the workers.Effective intervention measures should be taken to control ceramic dust hazard.关键词
