Trends Of Eom, B(A)P, Sulfates, And Nitrates In Air-Borne Particulate Matter In Eleven Proximate Locations In New Jersey During 1988, Sathish Pushpala

Theses

Air-borne particulate matter was collected at eleven proximate locations in New Jersey during the year 1988. Particulate matter was extracted in cyclohexane and acetone to separate non-polar and polar components. Particulate matter was also analyzed for B(a)P, Sulfates and Nitrates.

This report presents the inter-site and intra-site variation of concentrations of pollutants between summer and winter seasons. Levels of B(a)P varied from 0.12 to 0.03 ng/M³ between urban and rural sites. During winter, B(a)P concentrations were 5 times more than summer. Concentrations of Cyc which represent mostly primary pollutants, were found 3 times lower in rural sites. Ace fractions …

Quantitative Determination Of Formaldehyde In Ambient Air, Wen-Shao Chou

Theses

Formaldehyde has been shown in the laboratory to play a critical role in the chemistry of polluted air. The method which we discuss in this paper was evaluated under practical field conditions in the Northern New Jersey Staten Island Urban Air Toxics Project. Formaldehyde in ambient air is concentrated and derived by passing a known quantity of air through a silica column impregnated with 2,4-dinitrophenylhydrazine (DNPH). The silica is eluted with acetonitrile and the concentration of formaldehyde is determined by High Performance Liquid Chromatograph (HPLC) with UV detection. A description of procedural details for coating silica cartridges with 2,4-DNPH acidified …
