Henry's Law of Constants of some beta, gamma and delta-hydroxy alkyl nitrates of atmospheric interest

Article Abstract:

Researchers from the Weizmann Institute, Israel measured the OH reaction and the photolysis rate of organic nitrates by using Henry's Law of Constants to measure beta, gamma and delta-hydroxy nitrates in the troposphere.

Analysis of semivolatile organic compounds in atmospheric aerosols by direct sample introduction thermal desorption GC/MS

Article Abstract:

A technique to identify trace amounts of semivolatile organic compounds in the NIST Urban Dust standard and in atmospheric aerosols based on direct sample introduction (DSI) of small samples followed by used of a conventional GC injector for thermal desorption is examined. An abundance of organic matter within aerosols has been found in many regions of the troposphere, and contributes to many environmental issues like effects on cloud droplet chemistry, ozone production and physiological effects from inhaled particles.

Limitations of using stable isotope composition for the source identification of nitrate in agricultural soils

Article Abstract:

Two lysimeter field experiments tested the stable isotopic composition of nitrate. These tests were carried out to pinpoint the conditions in which the two-pronged isotope method can be used to identify the primary source of nitrate in agricultural soils.
