“…For MCA, the average concentration in summer 1994 exceeded 2 µg/L. These results are in agreement with previous determinations of MCA (300-4300 ng/L), DCA (0-4400 ng/L), and TCA in Germany and Austria (2)(3)(4). For TCA, the same annual fluctuation in concentrations has been observed in Austria.…”

“…MCA, for instance, is produced at a rate of more than 300 000 t annually () as intermediate in the production of carboxymethylcellulose, of some herbicides, and of other chemicals. Chloroacetic acids have been found in the atmosphere and in precipitation ( − ). Their origin is largely unknown.…”

“…Most published methods for trace analysis of environmental haloacetic acids are based on liquid-liquid partitioning (15)(16)(17). Alternatively, an ion chromatographic method has been used (3). EPA Method 552.1 (18) involves an anion exchanger and analyzes the methyl esters by GC-ECD.…”

From 1993 to 1995, chloroacetic acids have been determined in rainwater collected near the center of Zu ¨rich and in a rural area of Switzerland (Alpthal). The chloroacetic acids have been enriched either by evaporation or by anion exchanger, derivatized to their respective propyl esters, and determined by gas chromatography (GC) with electron capture detection (ECD), by coupled-column GC-ECD (GC-GC-ECD), or by GC/mass spectrometry (MS). Monochloroacetic acid is most abundant, followed by dichloro-and trichloroacetic acid. Concentrations range from 0.01 up to 9 µg/L; the dependence on meteorological conditions and sampling site is discussed.

“…Haloacetic acids have been found in various environments such as rain water [13][14][15][16][17][18][19], river water [9,19,20], and conifer needles [15,16,21,22]. The haloacetic acids released from industrial wastewater, river water, and rain water may accumulate in semienclosed water bodies such as Tokyo Bay, Japan, an area that is highly eutrophic and polluted.…”

Abstract-The distribution and sources of haloacetic acids in seawater in the vicinity of Tokyo Bay, Japan, were investigated, in view of the potential toxicity of these compounds to aquatic organisms. Haloacetic acids were extracted from water samples collected at 66 sampling stations (n ϭ 122). Concentrations of all nine haloacetic acids containing bromine and chlorine were determined by liquid chromatography-mass spectrometry. We found that concentrations of trichloroacetic acid (TCAA) were high (maximum: 20.3 g/L) compared to those of the other haloacetic acids in coastal seawater. The distributions and relative concentrations of TCAA and other haloacetic acids (monochloroacetic acid, dichloroacetic acid, and bromochloroacetic acid) suggest that their sources are not identical; discharge of wastewaters containing TCAA in the bay area is probably one of the main sources of the observed high concentrations of TCAA in seawater there. The mean concentrations of haloacetic acids in water samples and the results of incubation experiments of haloacetic acids in river water and seawater suggest that TCAA is relatively stable in the aquatic environment.
