TL;DR: The ambient air concentrations of 88 volatile organic compounds were determined in samples taken at 13 semi-rural to urban locations in Maine, Massachusetts, New Jersey, Pennsylvania, Ohio, Illinois, Louisiana, and California.

TL;DR: In this article, a multisorbent air-sampling cartridge was developed for the determination of 87 method analytes including halogenated alkenes and disulfide, and the eight most volatile compounds were determined using a 1.5-L air sample and a sample cartridge containing 50 mg of Carbotrap B and 280 mg of CARBOXEN 1000.

TL;DR: The U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program, completed in 1994-96, involved three sequential phases: (1) initial selection and preliminary screening of 130 candidate compounds on the basis of available information; (2) laboratory studies to ascertain the feasibility of analysis by purge-and-trap gas chromatography/ mass spectrometry; and (3) analysis of groundTvater, surface-water, and quality-control samples to determine the performance of laboratory methods on environmental samples as mentioned in this paper.

TL;DR: The increasing frequency of detection of the widely used petrol additive methyl terbutyl ether (MTBE) in both ground and surface waters is receiving much attention from media, environmental scientists, state environmental agencies, and federal agencies in the USA as discussed by the authors.
