“…The lack of these components in Ethion may support its significantly faster microbial degradation. The abiotic hydrolytic degradation products of Ethion; Ethion Monoxon, Ethion Dioxon, O,O ‐diethylthiophosphate and Thio‐formaldehyde were not observed using GC–MS [9,19]. Their absence may be due to a number of factors, however it seems most likely that Ethion and its degradation products were rapidly utilised for microbial growth.…”

The organophosphate pesticide, Ethion, remains a major environmental contaminant in rural Australia and poses a significant threat to environmental and public health. The aerobic degradation of Ethion by mesophilic bacteria isolated from contaminated soils surrounding disused cattle dip sites was investigated. Two isolates, identified as Pseudomonas and Azospirillum species, were capable of biodegrading Ethion when cultivated in minimal salts medium. The abiotic hydrolytic degradation products of Ethion such as Ethion Dioxon and O,O-diethylthiosphosphate were not detected. The data suggest the rapid degradation of Ethion to support microbial growth. The results have implications for the development of a bioremediation strategy.

Five different treatments of ethion on Valencia orange trees were compared for decay rates and for ethion monoxon and ethion dioxon production under different environmental conditions. The oxon metabolite levels observed were low and always below the residue level of ethion itself. There were no significant differences in the decay rates of ethion between treatments. A model of ethion decay utilizing environmental variables as a time base is presented. This model explains 94% of the variation observed in ethion decay during very wet and very dry periods in Florida. The application of these results and general experimental approach to worker safety reentry standards is discussed.
