Patterns and Temporal Trends of 7 Major Organic Solvent Induced Occupational Diseases in Guangdong, China 2006-2015

(1)Background: This study aimed to describe the distribution characteristics and temporal trends of major Organic Solvent induced occupational diseases (OSODs) in Guangdong Province, China.(2) Methods: A total of 1320 OSODs cases diagnosed from 2006 to 2015 were involved in this study, including information of case distribution, working age, industrial type, economic type and enterprise scale. 7 major OSODs accounted for the majority cases (1290 cases, 98%), including benzolism, n-hexane poisoning, 1,2-dichloroethane poisoning, trichloromethane poisoning, dimethyl formamide poisoning, benzene-induced leukemia and trichloroethylene-induced medicamentosa-like dermatitis.(3) Results: The incidence of OSODs was relatively higher in Shenzhen, Dongguan and Guangzhou than other districts. Most cases were related to light industry and electronics for industry type and small and medium-sized and private enterprises for enterprise scales and ownership types. Notably, the case number of benzolism and benzene-induced leukemia presented an increasing trend with year. The onset age of benzolism exhibited an increasing trend with year. The working age of onset of 1,2-dichloroethane poisoning, trichloromethane poisoning and dimethyl formamide poisoning were shorter than others.(4) Conclusions: Since the control and prevention of 7 major OSODs has achieved remarkable results, more measurements are needed to control benzolism and benzene-induced leukemia cases in Guangdong Province.
