Abstract：Objective To investigate the occupational hazard factors in the workplaces of artificial stone industry and their health hazards to workers, and to study the prevention and control measures. Methods The epidemiological investigation, engineering analysis, occupational hygiene detection and occupational health examination were used to analyze the occupational hazard factors of artificial stone industry and their health hazards to occupational groups. Results The main occupational hazard factors existed in the workplaces were dust, noise and chemical poisons (styrene, etc). The average levels of free silica in artificial stone and artificial quartz stone dust were 7.90% and 91.48% respectively. The over-standard rate of dust posts was 35.3%, and the over-standard rate of dust in raw material posts was 56.5%. The posts with 40-hour equivalent sound level higher than 80 dB(A) and than 85 dB(A) accounted for 96.2% and 73.1% respectively. The over-standard rate of styrene was 8.9%. Occupational health examination detected 4 cases of suspected pneumoconiosis (with the detection rate of 1.1%) and 4 cases of suspected noise-induced deafness (with the detection rate of 1.3%). The abnormal detection rates of high-kilovolt chest X-ray, pulmonary function, pure tone threshold audiometry, blood pressure, electrocardiogram, blood routine and urine routine examination were 20.3%, 17.1%, 58.3%, 18.4%, 29.8%, 7.9% and 29.0% respectively, showing statistically significant differences among the groups with different length of service (P<0.05). The longer the length of service, the higher the abnormal detection rate. The abnormal detection rates of pure tone threshold audiometry, high-kilovolt chest X-ray and urine routine examination in different types of enterprises showed statistically significant differences (all P<0.05). Conclusions The dust and noise in the workplaces of artificial stone industry in Yunfu City exceed the standard seriously, resulting in cumulative effects on the workers’ health. It is necessary to implement the rectification measures in the over-standard workplaces and strengthen the occupational health supervision.
