“…This systemic herbicide inhibits photosynthesis by preventing oxygen production (Wessels and Van der Veel, 1956) and blocks electron transfer at photosystem II in photosynthetic microorganisms and plants (Ducruet, 1991;Ohad and Hirschberg, 1992;Kless et al, 1994). The intensive use of this xenobiotic leads to surface water contamination by soil leaching and overland flow in agricultural and urbanized areas (Louchart et al, 2000;Thurman et al, 2000;Blanchoud et al, 2004). It is persistent in soil, water, and groundwater.…”

ABSTRACT:The potential toxicity of several herbicides-alachlor, diuron and its photo and biotransformation products, glyphosate and its metabolite aminomethyl phosphonic acid (AMPA)-to nontarget cells was assessed using two microorganisms frequently used in ecotoxicology, Vibrio fischeri and Tetrahymena pyriformis. Toxicity assays involved the Microtox 1 test, the T. pyriformis population growth impairment test employing three different processes (flasks, tubes, microplates), and the T. pyriformis nonspecific esterase activities test. Several IC 50 or EC 50 values are reported for each molecule. Alachlor exerted a toxic effect on the two nontarget cells used. The results for diuron and its photo and biotransformation products indicated that most of the metabolites presented nontarget toxicity higher than that of diuron. Glyphosate and AMPA had a less negative effect on T. pyriformis than on V. fischeri. Nevertheless, in all cases, glyphosate was found to be more toxic than AMPA. Comparison analysis of the sensitivity of the different tests showed that, in general, tests using the eukaryotic cell (T. pyriformis) were more sensitive than test using the prokaryotic cell (V. fischeri), and that a population growth criterion is more sensitive than an enzymatic criterion. The three different processes that could be used to evaluate effects on population growth rate were equally sensitive for the herbicides tested. A significant correlation between toxicity data and the hydrophobicity of the chemicals could only be established with the growth population test. This study demonstrates that it is essential to assess the toxicity of the metabolites formed to complete a more comprehensive study of the environmental impact of a polluting agent. # 2007 Wiley Periodicals, Inc.

“…Factors important to surface water runoff include high precipitation events, mode of application, soil moisture, soil texture and topography, type and amount of ground cover, and distance of transport. Lower pesticide concentrations have been observed when there is less erosion, dry coarse textured soils, ground cover, shallow slopes for transport on surfaces, and soil-incorporated pesticides [3,5,14,15].…”

“…Numerous other surface waters worldwide impacted by agricultural lands have reporting 2,4-D, mecoprop, or dichlorprop [7][8][9][10][11][12][13][14]. Pesticides can move in the environment by atmospheric transport, wet deposition, or be transported by surface rain-generated runoff from soils or surfaces [2,5,[14][15][16][17][18].…”

Surface water runoff from urban centers is a major source of environmental pollution which impacts water quality in downstream aquatic habitats. Phenoxyacid herbicides are some of the most widely globally used herbicides in agriculture and urban environments for weed control. Their transformation products which include chlorophenols can be more toxic than the active ingredients. We used LC/MS/MS to analyzed simultaneously these acid herbicides and their transformation products in stormwater retention ponds taken from an urban environment to examine the occurrence and potential release of these herbicides from urban inputs into downstream waters. 2,4-dichlorophenoxyacetic acid and mecoprop were detected in all samples collected from the ponds and at the highest concentrations, while 2-methyl-4-chlorophenoxyacetic acid was detected only in spring and summer. Two transformation products, 4-chloro-2-methylphenol and 2,4-dichlorophenol were detected in samples primarily at inlet locations on the ponds indicating that degradation had occurred in surface soils prior to surface water runoff.

“…Aminotriazole (also shortened to amitrole) for Europe (Blanchoud et al 2004 and Gilliom (2007) listed it as the most frequently detected of the seven herbicides used in urban areas, and Ryberg et al (2010) reported that, although prometon contamination was dominant in the US Northeast and Midwest, it was the most homogeneously represented herbicide for urban areas in the country as a whole. It is the most commonly used soil sterilant in urban areas (Kimbrough & Litke); locally unavailable to homeowners, it continues to be used in these areas by licensed applicators (Ifid.…”

“…That said, about 30,000 sports grounds have been inventoried in France: about one per town, as in all developed countries. Amenity use accounted for approximately 0.19% of pesticide use in Denmark, about 2.7% for the Netherlands and the United Kingdom, less than 3.4% for Germany, 0.6% for Finland and 1% in France (Blanchoud et al, 2004).…”
