对用于不同用途(如增塑剂和阻燃剂)的12种有机磷化合物(OP)进行了分析，这些化合物来自15个室内环境的沉淀物，以及从计算机屏幕和机盖上擦拭的测试样品。所分析的7种物质主导了1999年瑞典进口的有机磷农药，其中6种也被列为欧盟高生产量化学品。在所有样本中都发现了其中八种物质。大多数样品中含量最高的是三(2-丁氧基乙基)磷酸，含量在0.014~5.3g/kg之间，其次是三(2-氯乙基)磷酸、三(氯丙基)磷酸和三(1，3-二氯丙基)磷酸。在从计算机上擦拭测试样本中，磷酸三苯被证明是所分析的有机磷农药的主要成分(4.0ug/m(2))。这些化合物的潜在来源除其他外包括地板上光剂、聚氯乙烯地板覆盖物、室内装潢和塑料产品。在不同地点，有机化合物的分布模式不同，一般反映了其附近使用的建筑材料和消费品。(C)2003爱思唯尔有限公司。保留所有权利。
Twelve organophosphorus compounds (OPs), which are used for diverse purposes (e.g. as plasticizers and flame retardants), were analysed in settled house dust from 15 indoor environments and in wipe test samples from computer screens and covers. Seven of the substances analysed dominated Swedish imports of OPs in 1999, six of these are also listed as EU High Production Volume Chemicals. Eight of the substances were found in all samples. Tris(2-butoxyethyl)phosphate was the most abundant in most of the samples, with levels ranging from 0.014 to 5.3 g/kg followed by tris(2-chloroethyl)phosphate, tris(chloropropyl)phosphate and tris(1,3-dichloropropyl)phosphate. In wipe test samples from computers, triphenyl phosphate proved to be the main component of the OPs analysed (4.0 mug/m(2)). Potential sources of these compounds include, inter alia, floor polish, polyvinylchloride floor coverings, upholstery and plastic products. The distribution patterns of the OPs differed between the sites and generally reflected the building materials and consumer products used in their vicinity. (C) 2003 Elsevier Ltd. All rights reserved.
