Despite remaining uncertainties, a general picture of the biogeochemical cycling of HCOOH
and CH3COOH is beginning to emerge. These acids are ubiquitous vapor‐and aqueous …

The techniques currently available to measure the ambient atmospheric concentrations of
O3, O3-precursors (including the odd-hydrogen free radicals), the oxidation products of …

Despite more than 20 years of regulatory efforts, concern is widespread that ozone pollution
in the lower atmosphere, or troposphere, threatens the health of humans, animals, and …

An extensive set of volatile organic compounds (VOCs) and particulate organic matter
(POM) was measured in polluted air during the New England Air Quality Study in 2002 …

Knowledge of atmospheric mercury speciation is critical to understanding its fate once
released from point sources. The water-soluble compounds of Hg that exist in flue gases …

Breaking waves on the ocean surface produce bubbles that, upon bursting, inject seawater
constituents into the atmosphere. Nascent aerosols were generated by bubbling zero‐air …

We have determined the atmospheric concentrations of formic and acetic acid in gas and
particulate phases and in precipitation over a 15‐month time period at a site in eastern …

We constructed a new chemical ionization timeof-flight mass spectrometer (CI-TOFMS) that
measures atmospheric trace gases in real time with high sensitivity. We apply the technique …

Organic compounds were measured by proton transfer reaction‐mass spectrometry (PTR‐
MS) on board the National Oceanic and Atmospheric Administration's research ship Ronald …

Atmospheric gas-and particle-phase carboxylic acids and related compounds were
measured during October 1991 in a semiurban site in northeastern United States. Formic …
