The main sources of arsenic emission in Romania are ore smelters and refineries. Arsenic determinations were carried out by the silver diethyldithiocarbamate spectrophotometric method on hair and urine samples taken from smelter workers and individuals residing in two polluted areas and three areas not polluted by arsenic. Arsenic in hair was found to be a more reliable biologic test than tests on urine, obviously reflecting the differences in arsenic concentrations in workroom air. Repeated determinations for arsenic content after 3 years revealed a twofold increased rate in the 48 re-examined workers. Hair arsenic analysis in people living in two locations near an ore smelter and a refinery indicated high-levels compared to those of individuals residing in nonpolluted areas. Epidemiological studies are necessary in order to ascertain effects of heavy arsenic exposure in relation with concurrent exposures to respiratory irritants and metals.
罗马尼亚砷排放的主要来源是矿石冶炼厂和精炼厂。采用二乙基二硫代氨基甲酸银分光光度法，对冶炼厂工人以及居住在两个污染地区和三个未受砷污染地区的人员的头发和尿液样本进行了砷含量测定。结果发现，头发中的砷含量比尿液检测更能可靠地反映生物体内砷含量，这显然反映了工作场所空气中砷浓度的差异。3年后对砷含量进行的重复测定显示，在重新接受检查的48名工人中，砷含量增加了两倍。对居住在矿石冶炼厂和精炼厂附近两个地点的人群进行的头发砷分析表明，与居住在未受污染地区的人相比，他们头发中的砷含量较高。有必要开展流行病学研究，以确定高剂量砷暴露以及同时暴露于呼吸道刺激物和金属的影响。
