公路污染物主要由交通产生，在公路上反复堆积、抬升、漂移和移动。其中一些通过定期进行的道路清洁来清除，其他的则被雨水冲入接收水中。本研究的目的是调查公路污染物的特征，并对其在公路上的行为进行量化。研究区域是贯穿日本主岛的美新高速公路的一部分。对2004年12月至2005年11月期间的所有风暴事件进行了高速公路污染物径流调查。在调查中，样本是在暴风雨期间通过连续水样采集的。并对每个样品中的SS、TOC、TN、TP、重金属和多环芳烃(PAHs)等化学物质进行了测定。利用调查结果对暴雨过程中污染物径流特征进行了分析。全年清理公路污染物基本单位负荷。从而为公路污染的环境管理提供了一些有意义的认识。
Highway pollutants generated mainly from traffics are repeating accumulation, raise, drift and move on the highways. Some of them are removed by road cleanings done regularly, the others are flushed by stormwater into receiving water. The objectives of this study are to survey characteristics of the highway pollutants, and to quantify their behavior on the highways. The study area is a part of Meishin Expressway running through the main island of Japan. Surveys on pollutant runoff from the highway were done for all storm events through one year from December 2004 to November 2005. For the surveys, samples were collected by continuous water sampling during storm events. And chemical substances in each sample such as SS, TOC, TN, TP, heavy metals and polycyclic aromatic hydrocarbons (PAHs) for each class of particle size were measured. Using the results of the survey, characteristics of pollutant runoff during storm events were examined. And it cleared the basic unit loads for the highway pollutants throughout a year. As a result, some significant knowledge for the environmental management of highway pollution has been obtained.
