Abstract

Pesticides play a very important role in reducing losses and maintaining quality in crop production. Although positive effects of pesticide use are undeniable, adverse effects are frequent. This has led to a comprehensive reevaluation of the benefits of pesticide use and potential adverse effects on human health and the environment before placing them on the market. The fact that pesticides are designed to be toxic and are deliberately introduced into the environment, makes them a very important and strictly regulated group of pollutants. The most commonly used group of pesticides are herbicides, and their detection in surface water bodies has been repeatedly reported. In spite of being designed to be toxic to target species, adverse effects on other inhabitants of aquatic environments have also been observed. In order to prevent negative environmental effects, the registration process for active substances and plant protection products involves predictive environmental risk assessments (ERA). Reliable assessment of long-term effects on non-target species, natural populations and ecosystems is a priority and ERA process is constantly being improved.

地表水中的除草剂。行为、对水生生物的影响和风险评估
农药在减少作物损失、保持作物质量方面发挥着重要作用。虽然使用农药的积极影响是不可否认的,但不良影响也经常出现。这导致在将农药投放市场之前,对农药使用的益处及其对人类健康和环境的潜在不利影响进行全面重新评估。杀虫剂被设计成有毒的,并被故意引入环境中,这一事实使它们成为一组非常重要且受到严格管制的污染物。最常用的一类农药是除草剂,其在地表水中的检测已被多次报道。尽管被设计成对目标物种有毒,但也观察到对水生环境的其他居民的不利影响。为了防止负面的环境影响,活性物质和植物保护产品的注册过程涉及预测性环境风险评估(ERA)。对非目标物种、自然种群和生态系统的长期影响的可靠评估是一个优先事项,ERA过程正在不断改进。
