“…Spalding & Snow, 1989;Botta et al, 2009). In agricultural landscapes, the amount of pesticides contaminating surface water also depends on the methods and levels of application, and more generally on agricultural practice (Huber et al, 2000). Finally, in a recent paper of Wittmer et al (2010), it has been shown that five types of pesticide concentration patterns in surface water samples can be distinguished, and that these patterns reveal the relative contributions made by urban and agricultural land to the contamination of water by herbicides.…”

“…Due to the widespread use of pesticides, their residues are detected in various environmental matrices, like soil, water and air. Pesticide contaminations of surface waters have been well documented worldwide and cause a major issue that gives rise to concerns at local, regional, national and global scales due to the adverse effects of pesticide on the environment (Planas et al 1997;USGS 1999;Huber et al 2000;Cerejeira et al 2003). Pesticide residues reach the water body through direct runoff, leaching, careless disposal of empty containers, equipment washing etc.…”

The use of pesticide for crops leads to serious environmental pollution, therefore, it is essential to monitor and develop approaches to remove pesticide from contaminated environment. In this study, water samples were collected to monitor pesticide residues, and degradation of chlorpyrifos was also performed using soil bacteria. Identification of pesticide residues and determination of their levels were performed by high-performance liquid chromatography with photodiode array detector. Among 12 samples, 10 samples were found contaminated with pesticides. Chlorpyrifos was detected in four tested samples and concentrations ranged from 3.27 to 9.31 lg/l whereas fenitrothion ranging from (Below Detection Limit, \0.1 lg/ l) to 33.41 lg/l in the tested samples. Parathion was found in two tested samples at the concentration of 0.73 and 6.23 lg/l. None of the tested samples was found contaminated with Methoxychlor, DDT and Ethion. Three soil bacterial isolates, Pseudomonas peli BG1, Burkholderia caryophylli BG4 and Brevundimonas diminuta PD6 degraded chlorpyrifos completely in 8, 10 and 10 days, respectively, when 20 mg/l chlorpyrifos was supplied as sole source of carbon. Whereas, BG1, BG4 and PD6 took 14, 16 and 16 days, respectively, for complete removal of 50 mg/l chlorpyrifos. Chlorpyrifos degradation rates were found maximum by all three isolates at 2nd day of incubation for both tested concentrations. The results of the present study suggest the need for regular monitoring of pesticide residues in water, to protect the aquatic environment. Chlorpyrifos degrading bacterial isolates can be used to clean up environmental samples contaminated with the organophosphate pesticides.

“…These Tier 1 and Tier 2 models were developed and validated using empirical data derived from edge-of-field studies conducted during the 1970s to measure the range of potential herbicide exposures in aquatic systems (e.g., Wauchope, 1978). Similar approaches are used in Europe (Huber et al, 2000). Over the past decade more sophisticated models have been developed for higher-tier exposure assessments in the U.S. such as the Soil and Water Assessment Tool (SWAT; Gassman et al, 2007), and the Watershed Regression for Pesticides (WARP; Larson et al, 2004) and the Spatially Referenced Regression on Watershed Attributes (SPARROW; Schwarz et al, 2006) models.…”
