摘要: Pesticides may have adverse environmental effects if they are transported to groundwater and surface waters. The vulnerability of water resources contamination pesticides must therefore be evaluated. Different stakeholders, with different objectives requirements, interested in such assessments. Various assessment methods been developed the past. For example, pesticide leaching evaluated by indices overlay-based methods, statistical analyses monitoring data, or using process-based models fate. No single tool methodology is likely appropriate for all end-users since their suitability depends on available data specific goals assessment. overall purpose this thesis was develop tools, based that used Four tools varying interests: (i) a attenuation factor implemented GIS, where maps generated islands Hawaii (U.S.A.), (ii) simulation MACRO model support decision-makers at local authorities assess potential risks following normal usage drinking abstraction districts, (iii) linked soil root zone investigate mecoprop shallow deep fractured till, (iv) meta-model fate 'worst-case' assessments southern Sweden. strengths weaknesses approaches discussed.
