PESTICIDE HYDROXYL RADICAL RATE CONSTANTS: MEASUREMENTS AND ESTIMATES OF THEIR IMPORTANCE IN AQUATIC ENVIRONMENTS

摘要

Pesticide degradation by hydroxyl radicals produced in natural water is often cited as an important dissipation mechanism, yet its significance is rarely assessed with other dissipation processes occurring simultaneously in environment. The computer model Exposure Analysis Modeling System(EXAMS)is useful for this purpose because it incorporates other dissipation processes and allows the assessment of their dynamics under different environmental conditions.
