Epidemiological and occupational characteristics of occupational chemical poisoning in Tianjin city during 2006-2015

Abstract

Objective: To provide scientific evidence for the prevention and control measures of acute and chronic occupational poisoning by analyzing the epidemiological and occupational characteristics of occupational chemical poisoning cases reported in Tianjin city during 2006-2015. Methods: In September 2016, based on the China Disease Control and Prevention Information System, a database of occupational poisoning cases in Tianjin from 2006 to 2015 was established. The epidemiological characteristics of occupational poisoning were analyzed including three distributions firstly, and then the occupational characteristics were analyzed such as length of service, industry distribution and source of poison. Results: There were 174 occupational poisoning patients in Tianjin from 2006 to 2015, including 16 cases of acute poisoning (9.20%) and 158 cases of chronic poisoning (90.8%) , and the proportion of occupational poisoning cases reported in Binhai New Area is the highest. The number of reported cases of chronic occupational poisoning shows a downward trend. Occupational poisoning cases are concentrated mainly in the age of 40-60 years and length of service of 10-20 years. The high incidence of occupational poisoning mainly exists in the chemical raw materials and chemical manufacturing industry and general, professional equipment manufacturing industry. Acute poisoning was mainly by asphyxial gas (50.00%) , and chronic poisoning was mainly by organic solvent (43.67%) . Conclusion: The distribution of occupational poisoning cases in diverse toxic types and regions in Tianjin are quite different. The occupational safety precautions of the chemical raw materials and chemical products manufacturing and occupational poisoning control work in Binhai new area should be strengthened to reduce the occurrence of occupational poisoning.
