According to the Council Directive 91/414/EC pesticide damage should be assessed by considering the risk for persons arising from occupational, non-dietary exposure and risk to the environment. In this research an assessment for the pesticide damage by droplet spray drift was set up. The percentages of spray drift were estimated with the Ganzelmeier drift curves and the IMAG drift calculator. Knowing the percentages of drift and the applied doses of pesticide formulations in a given crop, the human and environmental exposures (water and bottom) were predicted. Thereupon risk indices were calculated for water organisms, soil organisms and bystanders. A risk index is the ratio of a predicted exposure to a toxicological reference value and gives an indication of the incidence and the severity of the adverse effects likely to occur. Considering the risk index it is possible to define the minimal width of an unsprayed field margin or "buffer zone" to reduce this risk at an acceptable level.
根据欧盟理事会指令91/414/EC，农药损害评估应考虑职业性非饮食接触对人员造成的风险以及对环境的风险。本研究建立了一种通过液滴喷雾飘移评估农药损害的方法。利用甘泽尔迈尔飘移曲线和IMAG飘移计算器估算喷雾飘移的百分比。在已知给定作物中飘移百分比和农药制剂施用量的情况下，预测了对人类和环境（水体和土壤）的暴露情况。据此计算了对水生生物、土壤生物和旁观者的风险指数。风险指数是预测暴露量与毒理学参考值的比值，可表明可能发生的不良反应的发生率和严重程度。考虑到风险指数，有可能确定未喷洒农田边缘或“缓冲区”的最小宽度，以便将这种风险降低到可接受的水平。
