Study on Synthetic Measures in Control of Occupational Lead Poisoning in Polyvinylchroride Pipe Industry

Objective To investigate the occupational lead poisoning status in PVC pipe industry and study synthetic measures in control and prevention for exploring an effective way to protect the workers' health. Methods An investigation of occupational hygiene was conducted in this industry.Synthetic control measures were implemented,including occupational health education,health protective engineering and occupational health management.Lead dust concentration was evaluated.The workers who were exposed to lead dust were checked regularly.Results There was serious occupational lead poisoning in the PVC pipe industry.By means of synthetic measures,the proportion of workplace where lead dust concentration exceeded the national standard was decreased from 82.2% to 44.6%(P0.001),and the rate of occupational lead poisoning was decreased from 7.2% to 0.8%(P0.001).Conclusion These synthetic control measures are effective to protect the workers in this industry.
