Data for the major pollutants; carbon monoxide, nitrogen oxides, photochemical oxidants, suspended particulates, and total hydrocarbons, have been presented. In addition, lead analysis and a justification for no sulfur oxides data are also discussed. This study was an integral part of an Environmental Impact Study carried out by the Chemistry Department and the Institute of Transportation Studies a Villanova University. Some of the pollutants were found to cause a situation of concern; namely, photochemical oxidants, suspended particulates and nitrogen oxides. On the otherhand, carbon monoxide and total hydrocarbons were found to be well below limits set by the EPA. Although no standards are set for lead in ambient air, the data showed very low concentrations of this pollutant in our particulate samples. Since oxides ofsulfur are more an industrial, rather than transportation, pollutant little relevance could have been found for the type of study performed.
已列出主要污染物的数据，包括一氧化碳、氮氧化物、光化学氧化剂、悬浮颗粒物和总碳氢化合物。此外，还讨论了铅分析以及未提供硫氧化物数据的理由。本研究是维拉诺瓦大学化学系和交通研究所进行的环境影响研究的一个组成部分。发现一些污染物令人担忧，即光化学氧化剂、悬浮颗粒物和氮氧化物。另一方面，发现一氧化碳和总碳氢化合物远低于美国环境保护局设定的限值。虽然没有为环境空气中的铅设定标准，但数据显示我们的颗粒物样本中这种污染物的浓度非常低。由于硫氧化物更多是一种工业污染物，而非交通污染物，对于所进行的这类研究而言，可能发现不了太大关联。
