HAZARDOUS CHEMICALS IN WATERS OF LITHUANIA

Water samples were collected from 45 locations throughout Lithuania be tween 1990 and 1993 as part of a study to determine the distribution a nd nature of hazardous chemicals in Lithuanian surface waters. Samples also were collected from groundwater beneath a pesticide storage land fill and from surface runoff water collected after an accidental fire at a pesticide storage warehouse, Organic chemicals were extracted fro m all the water samples by use of solid phase extraction (SPE) cartrid ges or disks while in Lithuania, and the cartridges and disks were tak en to the United States for elution and analysis by means of gas chrom atography, infrared spectrometry and mass spectrometry. The herbicide, alachlor, was identified in a surface water sample, s-triazine herbic ides (simazine, atrazine, and propazine) in groundwater samples, and c hlorine-substituted alkyl and aromatic carboxylic acids in the runoff water.
