The benefits of global pesticide use come at the cost of their widespread occurrence in the environment. An array of abiotic and biotic transformations effectively removes pesticides from the environment, but may give rise to potentially hazardous transformation products. Despite a large body of pesticide degradation data from regulatory testing and decades of pesticide research, it remains difficult to anticipate the extent and pathways of pesticide degradation under specific field conditions. Here, we review the major scientific challenges in doing so and discuss emerging opportunities to identify pesticide degradation processes in the field.
全球农药使用的益处是有代价的，其广泛存在于环境中。一系列非生物和生物转化有效地将农药从环境中去除，但可能会产生潜在危险的转化产物。尽管有大量来自监管测试和数十年农药研究的农药降解数据，但仍难以预测特定田间条件下农药降解的程度和途径。在这里，我们回顾了在这方面的主要科学挑战，并讨论了识别田间农药降解过程的新机会。
