First order degradation calculation
WebdC/dt = -KC (8.10) where K = first-order rate constant (in time–1 or per hour) From equation 8.10, it is clear that a first-order process is the one whose rate is directly proportional to the concentration of drug undergoing reaction i.e. greater the concentration, faster the reaction. WebSep 21, 2024 · This guidance covers the general methods to be used in determining the first-order degradation model input. Frequently, biotransformation laboratory studies do not follow a firstorder degradation pattern; yet standard pesticide fate models (e.g. PRZM, EXAMS) require firstorder degradation inputs.
