Micro-mechanism and rate constants for OH-initiated degradation of methomyl in atmosphere.

Highlights: [•] OH-initiated degradation of methomyl in atmosphere has been investigated. [•] The rate constant of Z-methomyl is 5.33×10−14 cm3 molecule−1 s−1. [•] The rate constant of E-methomyl is 7.45×10−14 cm3 molecule−1 s−1. [•] Z-methomyl can exist longer than E-methomyl in atmosphere. [ABSTRACT FROM AUTHOR]
