摘要

众所周知,油漆和涂料行业向大气排放大量颗粒物(PM)。然而,没有详细研究暴露水平,特别是在考虑亚微米(PM1)和超细颗粒(颗粒直径低于100纳米)时。越来越多的证据表明,肺部接触这些大小的碎片可能非常有害。本研究调查了两个油漆工厂在每个工厂的两个搅拌站的粉末处理和油漆混合过程中的颗粒排放。在每种情况下,测量都在搅拌站同时进行(近场;NF),以及进入车间远场(FF)的5-15米距离,以及工人的呼吸区。颗粒浓度(5nm至30µm)使用高时间分辨率颗粒仪器测量,并使用PM1旋风过滤采样器进行重量测量。PM1过滤器也通过扫描电子显微镜(SEM)进行了表征。NF颗粒和粉尘浓度水平与浇注粉末有关,并用于表征局部控制的排放和效率。NF颗粒数浓度比FF浓度高1000 ~ 40000cm(-3)。纳滤粒子主要分布在100 - 500纳米之间,辐射似乎发生在短时间内。个人PM1暴露水平在0.156和0.839mg m(-3)之间变化,比固定的NF PM1浓度高1.6-15倍。扫描电镜(SEM)结果证实,人体接触量和NF颗粒主要受所使用的颜料和填料的影响。通过使用实时粒子监测仪进行个人暴露测量,可以更好地了解整个时间的个人暴露。本研究为涂料行业的PM暴露特征和浓度水平提供了更好的见解。

Worker Exposure and High Time-Resolution Analyses of Process-Related Submicrometre Particle Concentrations at Mixing Stations in Two Paint Factories.

The paint and coatings industry is known to have significant particulate matter (PM) emissions to the atmosphere. However, exposure levels are not studied in detail especially when considering submicrometre (PM1) and ultrafine particles (particle diameter below 100nm). The evidence is increasing that pulmonary exposures to these size fractions are potentially very harmful. This study investigates particle emissions during powder handling and paint mixing in two paint factories at two mixing stations in each factory. In each case measurements were made simultaneously at the mixing station (near-field; NF), as well as at 5-15 m distance into the workroom far-field (FF), and in the workers breathing zone. Particle concentrations (5nm to 30 µm) were measured using high time-resolution particle instruments and gravimetrically using PM1 cyclone filter samplers. The PM1 filters were also characterized by scanning electron microscopy (SEM). The NF particle and dust concentration levels were linked to pouring powder and were used to characterize the emissions and efficiencies of localized controls. NF particle number concentrations were 1000-40000cm(-3) above FF concentrations. NF particles were mainly between 100 and 500nm and emissions appeared to occur in short bursts. Personal PM1 exposure levels varied between 0.156 and 0.839mg m(-3) and were 1.6-15 times higher than stationary NF PM1 concentrations. SEM results verified that the personal exposure and NF particles were strongly dominated by the pigments and fillers used. Better understanding of the entire temporal personal exposure could be improved by using real-time particle monitors for personal exposure measurements. This study provides better insight into PM exposure characteristics and concentration levels in the paint industry.
