在环境污染问题中,农药虽比其他污染环境的工业三废和肥料的量要小的多,但占有特殊的地位,主要因为它们有高度的生物活性,因而在此有必要提出“农药环境毒理学”的研究,它主要研究环境内存在的农药对生物系的影响,有时也指对非目标生物的影响。“非目标”这一词是很重要的,因为环境污染的危害性通常与农药或农药衍生物的意外副作用相关连。这些副作用的出现是农药的自然转移和生物的浓集所引起的。使用农药概况图1:表示美国农药生产的总趋势。整个农药中的杀虫剂可粗略地以总吨位的一半来计算。其中除草剂增长最快,预计不久将会超过杀虫剂的总产量。
In environmental pollution problems, although pesticides are much smaller than those of other industrial wastes and fertilizers that pollute the environment, they occupy a special position mainly because they have a high degree of biological activity. Therefore, it is necessary to put forward “Pesticide Environmental Toxicology ”Research, which focuses on the impact of pesticides that exist in the environment on biological systems, and sometimes on non-target organisms. The term “non-target” is important because the dangers of environmental pollution are often linked to the unintended side effects of pesticides or pesticide derivatives. The emergence of these side effects is caused by the natural transfer of pesticides and biological concentration. Overview of the use of pesticides Figure 1: The general trend in the production of pesticides in the United States. Pesticides throughout the pesticide can be roughly calculated in half of the total tonnage. Among them, the fastest growing herbicides are expected to exceed the total pesticide production soon.
