Problems solved by technology

The existing monitoring platform and registration management system are not capable of real-time collection of data on the concentration of harmful chemical substances. Confirmation of key control points depends on experience and judgment. In case of special circumstances, it is impossible to promptly remind respiratory protection upgrades. The statistical analysis function is not strong enough to carry out professional work. Exposure and health monitoring data, risk result prediction and trend analysis, limited ability to carry out risk prediction and early warning

Embodiment 1

[0067] The quantitative risk monitoring and early warning method for occupational exposure to chemical carcinogens according to the present invention specifically includes: developing the content of risk monitoring and early warning from the four-step risk assessment method of risk identification, exposure assessment, dose-response assessment and risk characterization:

[0068] S1. Risk identification: collect the data required for dose-response evaluation and exposure assessment, determine which chemical substances are exposed to through risk identification, and whether these chemical substances will cause adverse health effects, and qualitatively analyze and describe the nature and intensity of the effects .

[0069] Enter the workplace information, exposure population information and risk identification results of chemical carcinogens into the registration management system, analyze the collected data and describe the results, and maintain and update them regularly.

[0070...

Embodiment 2

[0187] The second embodiment is based on the quantitative risk monitoring and early warning method for occupational exposure to chemical carcinogens described in the first embodiment, to build a quantitative risk monitoring and early warning system for occupational exposure to chemical carcinogens, to carry out monitoring and early warning of key occupational disease hazards, and to carry out risk management;

[0188] The quantitative risk monitoring and early warning system for occupational exposure to chemical carcinogens adopts such as figure 2 The technical route shown, realizes such as image 3 The design and registration management of the occupational hazard early warning indicator system and early warning model based on networked big data are as follows:

[0189] 1. Online collection of real-time monitoring concentration data and abnormal conditions of chemical carcinogens in the air of key industries, key enterprises or positions / sites, physical examinations of worker...

Embodiment 3

[0220] The third embodiment is a specific application case of the present invention:

[0221] (1) Epidemiological data collected:

[0222] In the 1980s, the Chinese Academy of Preventive Medicine, in cooperation with the National Cancer Institute (NCI), conducted a retrospective cohort study of occupational exposure to benzene in China. All hematological tumors and related diseases were used as the observation end point. The study cohort included 74,828 benzene-exposed workers and 35,805 non-exposed workers in a total of 672 factories in 12 cities in China between 1972 and 1987. Involving benzene industry including paint, printing, shoemaking, paint and other chemicals manufacturing. The survey has a large sample size, a long follow-up time, and a clear classification of the tumor types under consideration. There is a clear survey on the concentration and time of receiving benzene, which better reflects the death of leukemia caused by occupational exposure to benzene in the ...

Abstract

The invention provides a chemical cancerogen occupational exposure quantitative risk monitoring and early warning method. The method comprises the steps of collecting workplace information and exposed crowd information, performing risk identification on chemical substances of a workplace, performing real-time online monitoring based on the Internet of Things, and performing exposure evaluation. Analyzing and determining key control points with high exposure; selecting a corresponding dose-reaction model according to the determined chemical carcinogen, and substituting the dose-reaction model into a carcinogenic risk formula to realize dose-reaction evaluation; the carcinogenic risk is characterized. According to the invention, effective prediction, monitoring and early warning of occupational disease hazards of chemical carcinogens are realized, and the supervision level is improved.

Description

technical field [0001] The invention belongs to the field of occupational health and occupational disease control, and particularly relates to a quantitative risk monitoring and early warning method and system for occupational exposure of chemical carcinogens. Background technique [0002] IARC (International Agency for Research on Cancer) labels confirmed human carcinogens as G1, and occupational exposure to chemical carcinogens may cause occupational tumors. Group G1 chemical carcinogens that still exist in industry include vinyl chloride, benzene, 1,3-butadiene, ethylene oxide, formaldehyde, etc. [0003] In order to control occupational disease hazards caused by chemical carcinogens, monitoring high-risk groups of occupational cancer is the key to occupational cancer prevention and control. At present, my country's occupational disease prevention and control information construction has not established a complete occupational cancer monitoring network, nor has it formed ...
