BACKGROUND
The aim of this study was to assess occupational exposure to total and respirable dust of aluminum and its compounds in several plants, which use aluminum alloys in their production processes.
MATERIAL AND METHODS
The investigations were conducted at 37 workplaces in 5 plants. Air samples were collected at three groups of workplaces: smelting, founding and mechanical working of products. Air samples were taken according to the principles of personal dosimetry. Aluminum concentrations (total and respirable dust) were determined by atomic absorption spectrometry with a graphite tube and Zeeman background correction.
RESULTS AND CONCLUSIONS
It was found that differential exposure to total and respirable dust of aluminum and its compounds occurred at all investigated workplaces. At the majority of workplaces, concentrations of aluminum total dust and aluminum respirable dust were higher than 0.1 of the relevant value of maximum admissible concentration (MAC), but at none of these workplaces 0.4 of this value was exceeded.
背景
本研究的目的是评估几家在生产过程中使用铝合金的工厂中铝及其化合物的总粉尘和可吸入粉尘的职业暴露情况。
材料与方法
调查在5家工厂的37个工作场所进行。在三组工作场所采集空气样本：产品的熔炼、铸造和机械加工。根据个人剂量测定原则采集空气样本。铝浓度（总粉尘和可吸入粉尘）通过带石墨管和塞曼背景校正的原子吸收光谱法测定。
结果与结论
发现在所有调查的工作场所，铝及其化合物的总粉尘和可吸入粉尘存在差异暴露。在大多数工作场所，铝总粉尘和铝可吸入粉尘的浓度高于最大允许浓度（MAC）相关值的0.1，但这些工作场所均未超过该值的0.4。
