摘要

为评价燃煤电厂生产性粉尘的职业健康风险，研究了燃煤电厂一线操作人员的粉尘暴露情况，采用蒙特卡罗模拟法、概率风险评估法和健康损害分析法对不同类型粉尘暴露的健康风险进行了定量评价。结果表明，在所有职业中，锅炉机组除灰和除渣人员的健康风险最大，锅炉检查和脱硫检查人员的健康风险最小，皮带检查和除灰人员的健康损害最大。体重(BW)和平均时间(AT)具有负敏感性，对员工平均健康等级影响较大的参数依次为暴露时间(ED)、粉尘浓度、吸入率(IR)和暴露时间(ET)。

Health risk assessment caused by productive dust in coal-fired power plants

In order to evaluate occupational health risks caused by productive dust in coal-fired power plants, dust exposure of first-line operators in such plants was explored, and their health risks from exposure to different types of dust were assessed quantitatively by using Monte Carlo simulation method, probability risk assessment and health damage analysis method. The results show that among all occupations, ash removal and slag removal of boiler unit are exposed to the greatest health risk while boiler inspection and desulfurization inspection to minimal risk, and belt inspection and ash removal operators are faced with maximum damage to health. It is also found that body weight (BW) and average time (AT) have negative sensitivity, and parameters which have great impacts on average employee health rank as AT, exposure duration (ED), dust concentration, inhalation rate (IR) and exposure time (ET) in turn.
