Abstract:
Objective To analyze the epidemiological characteristics of newly diagnosed occupational chemical poisoning (OCP) cases in Guangdong Province from 2006 to 2023. Methods The basic information of newly diagnosed OCP cases in Guangdong Province from 2006 to 2023 was collected from the Occupational Disease Report Card of the occupational disease network reporting system in China. The epidemiological characteristics were analyzed by the descriptive epidemiological methods. Results A total of 2 201 newly diagnosed OCP cases were reported in Guangdong Province during 2006-2023, showing a fluctuating downward trend with an average annual decrease rate of 6.98%. Occupational acute chemical poisoning (OACP) and occupational chronic chemical poisoning (OCCP) accounted for 18.08% and 81.92% of cases, respectively. Among the OACP cases, the top five disease categories were other OCP, occupational acute 1,2-dichloroethane poisoning, occupational acute dimethylformamide poisoning, occupational acute organophosphate poisoning, and occupational acute hydrogen sulfide poisoning, accounting for 77.14% (307/398). Among the OCCP cases, the top five disease categories were occupational chronic benzene poisoning, occupational chronic n-hexane poisoning, occupational chronic lead poisoning, occupational chronic cadmium poisoning and occupational chronic mercury poisoning, accounting for 97.67% (1 761/1 803), with occupational chronic benzene poisoning being the most prevalent (67.22%). Newly diagnosed OCP cases were predominantly concentrated in the Pearl River Delta region (96.00%), particularly in Dongguan City, Shenzhen City, and Guangzhou City, accounting for 69.29%. The cases mainly occurred in the manufacturing industry, domestically funded enterprises, and small- and medium-sized enterprises, accounting for 93.82%, 54.98%, and 70.88%, respectively. Males accounted for 52.57% of cases, individuals aged <50 years accounted for 91.32%, and workers with <5 years of service accounted for 60.29%. There were significant differences in the distribution of gender, age and length of service between the OACP and OCCP cases (all P<0.01). Conclusion The newly diagnosed OCP cases in Guangdong Province demonstrates a pattern characterized by concentration in disease types, geographic regions, industries, enterprise types, and affected populations, along with a high level of social risk, which was summarized as the feature of "five areas of concentrations and one high-risk factor".
