邻苯二甲酸酯在许多塑料中用作增塑剂，一些研究表明它们具有毒性。随着时间的推移，邻苯二甲酸酯会逐渐释放出来，因此可以想象，它们会对健康构成重大风险。这项研究的目的是调查各种邻苯二甲酸酯排放的温度依赖性，并估计这些排放在不同温度下的健康风险。研制了一种被动式采样器，用于测量塑料材料表面邻苯二甲酸酯的通量。用这个取样器，我们检测了三种广泛使用的塑料材料：合成革、墙纸和乙烯基地板。这些材料在20℃下观察到的邻苯二甲酸二乙酯、邻苯二甲酸二丁酯和邻苯二甲酸二乙基己酯(DEHP)的最大排放量分别为0.89、0.77和14mug m(-2)h(-1)。在80℃时的排放量分别为2.8、4.5×10(2)和1.5×10(3)mug m(-2)h(-1)。结果表明，这种温度依赖性主要由邻苯二甲酸酯的类型决定，而不是由材料的类型决定。温度依赖结果的估计表明，白天被丢弃在阳光下的车辆中的DEHP浓度可能超过日本厚生劳动省的推荐水平。(C)2003爱思唯尔有限公司。保留所有权利。
Phthalate esters are used as plasticizer in many plastics, and several studies have shown their toxicity. Phthalate esters are gradually emitted over time, and so it is conceivable that they pose a significant health risk. This study aims to investigate the temperature dependence of the emissions of various phthalate esters and to estimate the health risks of these emissions at various temperatures. A passive-type sampler was developed to measure the flux of phthalate esters from the surface of plastic materials. With this sampler, we examined three widely used plastic materials: synthetic leather, wallpaper and vinyl flooring. The observed maximum emissions of diethyl phthalate, dibutyl phthalate, and diethylhexyl phthalate (DEHP) from these materials at 20degreesC were 0.89, 0.77, and 14 mug m(-2) h(-1), respectively. Emissions at 80degreesC were 2.8, 4.5 x 10(2), and 1.5 x 10(3) mug m(-2) h(-1), respectively. The results showed this temperature dependence is determined primarily by the type of phthalate ester and less so by the type of material. The estimation from the results of temperature dependence indicated the concentration of DEHP in a vehicle left out in the sunshine during the day can exceed the recommended levels of Japan Ministry of Health, Labour and Welfare.
