ABSTRACT During sowing of pesticide-treated seeds, pesticide-laden dust and abraded seed particles may be emitted to the environment, possibly leading to environmental contamination and posing health risks. In many countries there is currently no legislation concerning the acceptable amount of dust of treated seeds. This study aimed to gain insight in the abrasion potential of available pesticide-treated seeds and its associated factors. The abrasion potential of 45 seed samples of 7 different species (viz. sugar beet, oat, barley, wheat, spelt, pea, and maize) was determined using the Heubach test and amounts of dust were expressed as g 100 kgseeds−1, g 100,000 seeds−1, and g ha−1. The abrasion potential fell generally within the boundaries of maximum permissible values adopted by different countries. Species, seed treatment company, number of active ingredient (AIs) and combination of AIs had significant effects on the abrasion potential, whereas little or no effect of agitation and conservation was found. However, species were situated differently with respect to each other depending on the unit in which the abrasion potential was expressed. A standard unit that takes into account the species’ seed rate is suggested to give the fairest assessment of dust drift risk and would allow international comparison.

使用 Heubach 测试评估经过农药处理的种子的磨损潜力


摘要 经农药处理的种子在播种过程中，含有农药的粉尘和磨损的种子颗粒可能会排放到环境中，可能导致环境污染并造成健康风险。在许多国家，目前还没有关于处理种子的可接受粉尘量的立法。本研究旨在深入了解现有农药处理种子的磨损潜力及其相关因素。使用 Heubach 测试测定 7 个不同物种（即甜菜、燕麦、大麦、小麦、斯佩尔特小麦、豌豆和玉米）的 45 个种子样品的磨损潜力，粉尘量表示为 g 100 kgseeds−1, g 100,000 颗种子−1，g ha−1。磨损潜力总体上落在不同国家所采用的最大允许值的范围内。品种、种子处理公司、活性成分 (AI) 数量和 AI 组合对磨损潜力有显着影响，而搅拌和保存的影响很小或没有。然而，根据表示磨损潜力的单位，物种之间的位置不同。建议采用考虑物种种子率的标准单位，以对尘埃漂移风险进行最公平的评估，并允许进行国际比较。
