Embodiment Construction

[0052] For the technical content and method implementation steps of occupational exposure to benzene and carcinogenic risk analysis in the workplace, see image 3 .

[0053] Case Study of Occupational Exposure to Benzene

[0054] 1. Risk identification

[0055] (1) Occupational hazard factors and exposure routes

[0056] A large-scale petrochemical company newly built a 500,000-ton / year styrene production plant, using the traditional process of catalytic dehydrogenation of ethylbenzene to produce styrene. The main raw materials for production are ethylene and benzene, and there are a large amount of benzene and ethylene in each process unit. , ethylbenzene and other toxic and harmful substances.

[0057] Styrene production is carried out in an open-air closed environment, with mature and advanced production technology and a high degree of automation, which has caused a lot of misunderstanding in people's understanding. The dose is very small, the degree of exposure will be...

Abstract

The invention relates to a workplace benzene occupational exposure and carcinogenic hazard analysis method. A program of an adopted technical method analyses the risk by steps of a health risk assessment four-section method which is the most popular in the world, namely, risk identification, dose-response assessment, exposure assessment and risk characterization. The method comprises the following steps: numerically simulating an inner exposure dose by using ERDEM software; analyzing a quantitative relation between the exposure dose and the carcinogenic response by using a multi-step model; and analyzing the probability distribution rule by using a crystal ball Monte Carlo analogue method aiming at the uncertainty of the exposure and the risk. The invention firstly and perfectly provides a workplace benzene occupational exposure and carcinogenic hazard analysis technology; and the method can be applied to the work such as health monitoring, occupational exposure and health risk assessment and the like of high-risk occupational groups.

Description

technical field [0001] The invention belongs to the field of preventive medicine occupational health and occupational disease control technology and petrochemical occupational health risk management science and technology, especially proposes a workplace benzene occupational exposure and carcinogenic risk analysis technology based on internal exposure, which is mainly applied to the health of high-risk occupational groups. Monitoring, occupational exposure and health risk assessment. Background technique [0002] The petrochemical industry is a high-risk industry and high-risk enterprise with occupational poisoning, occupational tumors and other occupational diseases. The health hazards caused by occupational exposure to chemical carcinogens such as benzene produced and used in the petrochemical industry are a common concern at home and abroad. Benzene is a strong carcinogen, which is listed as a class 1 carcinogen by the World Health Organization, so it is particularly impo...
