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.

Assessment of the effects on land use, social, economic, historic and natural environment as a result of highway construction are discussed. Predictions of these effects on the various categories twenty years hence are also presented. Information of this type is a necessary segment of an environment impact study soas to conform to EPAand Department of Rransportation (DOT) guidelines.

A three (3) month survey was conducted to investigate the concentration levels of several of the more persistent air pollutants, ie., hydrocarbons, photochemical oxidants, suspended particulate matter and lead. Samples were collected at various sites in a rural community (population 14, 800) in Eastern Pennsylvania. Results indicated that no pollution problem existed during the survey interval. Analytical data for above named pollutants are presented.
