Abstract The nature of nitrate (14797558) (NO3) in coarse continental environments was studied. NO3 aerosols were collected in two size fractions at a remote site in South Dakota, an urban site in Denver, a rural site in Louisiana near the Gulf Coast, a rural site in the Blue Ridge Mountains of Virginia, and an urban site in Detroit. Several different types of samples were used during the investigation. One sampler collected aerosols up to 30 micrometers (microm) in diameter while another collected aerosols less than 2.5microm in diameter. A manual dichotomous sampler was used to collect fractions less than 3.5microm and fractions between 3.5 and 15microm. Subsequent NO3 and sulfate (14808798) (SO4) determinations were made using ion chromatography. In South Dakota, Louisiana, Virginia, and Detroit, Michigan, the percent coarse NO3 fractions were 77, 76, 72, and 90 percent, respectively. However, in Denver only 18 percent of NO3 was collected in the coarse fractions. The SO4 was predominantly in the fine fraction at all sites. The author concludes that strong correlations between NO3 and the soil constituents aluminum (7429905), silicon (7440213), calcium (7440702), titanium (7440326), and iron (7439896) suggest that NO3 is associated with entrained soil dust.
