Little information has been developed regarding the effect of rain in cleansing the air of pollutant-bearing particulates. Preliminary comparison of the levels of several important elements in urban, suburban, and rural areas during a 14-day dry spell and shortly after a rainfall is made. Air samples were drawn through cellulose acetate filters which were subsequently analyzed by x-ray photoelectron spectroscopy for sulfur, lead, nitrogen, carbon silicon, and oxygen. Higher levels of pollutants were found in the urban area compared to the rural area. Suburban area seemed to contain a substantial amount of sulfur. Higher sulfur and nitrogen emissions from the newer catalyst-equipped cars, likely to be more prevalent in the suburbs, may be the source of these higher levels. From previous though uncontrolled samplings these levels have increased over the past few years.
