Analysis method for risk of electric welder pneumoconiosis caused by electrowelding fume occupation exposure

Abstract

The invention provides a quantitative evaluation method for a risk of electric welder pneumoconiosis caused by electrowelding fume occupation exposure.The method comprises the steps that risk identification, exposure evaluation, dosage-reaction evaluation and risk characterization are adopted; a statistical distribution test is performed through SPSS software on the basis of on-site detection data of the electrowelding fume concentration to obtain probability distribution of the received fume concentration; a logistic model is selected to serve as a dosage-reaction model of the electric welder pneumoconiosis, model parameters are determined through population epidemiology data, and a dosage-reaction model used for evaluating the electric welder pneumoconiosis caused by electrowelding fume occupation exposure is obtained; Monte Carlo simulation of a carcinogenic risk value is performed by adopting crystal ball software, and the risk of the electric welder pneumoconiosis caused due to the fact that a crowd works in the electrowelding fume exposure environment for a long term is characterized.The quantitative evaluation method for the risk of the electric welder pneumoconiosis caused by electrowelding fume occupation exposure is completely presented for the first time and applied to occupational hazard evaluation of building projects and occupational hazard risk management of the electric welder pneumoconiosis.

Description

technical field [0001] The invention belongs to the field of preventive medicine occupational health and occupational disease control technology and occupational health risk management science and technology, and in particular proposes a risk analysis method for welder's pneumoconiosis caused by occupational exposure to welding fume, which is mainly used in the evaluation of occupational disease hazards in construction projects and the detection of welder's pneumoconiosis Occupational hazard risk management, etc. Background technique [0002] According to the incidence of occupational diseases reported in many places in China in recent years, pneumoconiosis still ranks first among occupational diseases. While silicosis, coal workers' pneumoconiosis and other traditional common pneumoconiosis occur, due to changes in industry structure characteristics, the number of welder's pneumoconiosis in some areas shows a trend of increasing year by year, and even becomes the main disea...

Problems solved by technology

There is a big gap between our country and the international advanced level in the application of welder pneumoconiosis risk analysis technology caused by occupational exposure to welding fume. Due to the lack of special models and methods to quantify the possible exposure and the health risks caused by it, it has not been practically applied so far. Work on health monitoring, occupational health testing, occupational exposure and health risk assessment of people exposed to occupational welding fumes
