Previous environmental monitoring indicated that di (2-ethylhexyl) phthalate (DEHP) was released into the environment. This study collected both water and sediment samples from the source area, deltas of major rivers discharging into the Gulf of Thailand, and 2 tourist beaches from February 2007-August 2009. The analyses showed that the highest DEHP concentrations were 8.64 microg l(-1) and 14.51 microg g(-1) for water and suspended sediment samples, respectively. Nevertheless, the monitoring results indicated that the dispersion of DEHP was limited to the source area. The ecological risk assessment indicated that the ecological risk did not exceed the acceptable level for the current degree of contaminations.
先前的环境监测表明邻苯二甲酸二（2-乙基己基）酯（DEHP）已释放到环境中。本研究于 2007 年 2 月至 2009 年 8 月，分别采集了水源地、主要入海河流三角洲以及 2 个旅游海滩的水和沉积物样品。分析结果表明，水中 DEHP 的最高浓度为 8.64μg/L，悬浮沉积物中 DEHP 的最高浓度为 14.51μg/g。然而，监测结果表明 DEHP 的分散仅限于源地区域。生态风险评估表明，在当前污染程度下，生态风险未超过可接受水平。
