由于缺乏工业卫生数据、所用溶剂的异质性以及影响工人实际接触溶剂量的工作实践的可变性,难以量化建筑油漆工接触混合有机溶剂的情况。本报告描述了一种尝试,以获得一个估计的空气中的溶剂暴露使用问卷调查的人口建设和维修油漆工。这一接触指数(EI)是一年使用的总加仑数减去呼吸器可吸收的部分的加权平均数,加权数是根据使用方法(喷洒、滚动、刷涂)和通风情况(室内与室外的时间百分比)确定的。为确定EI对几个参数所选值变化的敏感性而进行的分析表明,该指数对我们使用的基本假设相对不敏感。EI的一个组成部分(自我报告的工作时间)与工会工资记录相关。EI似乎提供了一个有用的相对(而不是绝对)估计空气中接触有机溶剂混合物,可用作剂量替代流行病学调查。
Quantifying the exposure of construction painters to mixed organic solvents is difficult in the face of a lack of industrial hygiene data, the heterogeneity of the solvents used, and the variability in work practices which influences the amount of solvents to which a worker is actually exposed. This report describes an attempt to derive an estimate of airborne solvent exposure using questionnaire responses in a population of construction and maintenance painters. This exposure index (EI) is a weighted average of the total number of gallons used a year minus the fraction which would be absorbed by a respirator, where the weights are based on the method of application (spraying, rolling, brushing) and the presence of ventilation (per cent time inside v outside). An analysis performed to determine the sensitivity of the EI to variations in the values chosen for several parameters showed that the index is relatively insensitive to the underlying assumptions that we have used. One component of the EI (self report of hours worked) correlated well with union payroll records. The EI appears to provide a useful relative (not absolute) estimate of airborne exposure to organic solvent mixtures which may be used as a dose surrogate in epidemiological investigations.
