Vulnerability Assessments of Pesticide Leaching to Groundwater
Stenemo, F., 2007. Vulnerability assessments of pesticide leaching to groundwater. Doctoral thesis. ISSN 1652-6880, ISBN 978-91-576-7356-5. Pesticides may have adverse environmental effects if they are transported to groundwater and surface waters. The vulnerability of water resources to contamination of pesticides must therefore be evaluated. Different stakeholders, with different objectives a...
متن کاملComparison of pesticide leaching potential to groundwater under EU FOCUS and site specific conditions.
The EU FOCUS scenarios are a set of nine standard scenarios based on a combination of crop, soil and weather data used throughout Europe to evaluate the leaching potential of pesticides to groundwater. In Ireland, two predefined EU FOCUS scenarios (Okehampton and Hamburg) appear to be the most appropriate to Irish conditions. However, there is concern that these scenarios may not accurately rep...
متن کاملSensitivity analyses for four pesticide leaching models.
Sensitivity analyses using a one-at-a-time approach were carried out for leaching models which have been widely used for pesticide registration in Europe (PELMO, PRZM, PESTLA and MACRO). Four scenarios were considered for simulation of the leaching of two theoretical pesticides in a sandy loam and a clay loam soil, each with a broad distribution across Europe. Input parameters were varied withi...
متن کاملReviewing Mathematical Models for Pesticide Leaching Studies
Leaching is an unavoidable phenomenon associated with the pesticide applications. Leaching of pesticide does not only indicate the efficiency of a pesticide molecule, but also degree of the environmental contamination. Leaching is the process by which a pesticide molecule enters the soil-water ecosystem. Hence, to access the leaching behavior of a pesticide molecule, various models are used glo...
متن کاملidentification of regions vulnerable to trickle irrigation clogging based on groundwater quality using arcgis
an accurate design of drip irrigation requires water quality analysis that helps attain a better emission uniformity coefficient. this study examined aquifer qualitative parameters in the north of khuzestan province to assess the applicability of groundwater in trickle irrigation systems. for this purpose, interpolation technology was used to map chemical parameters collected from 104 deep well...
