Witryna1 kwi 2024 · Most organophosphate pesti- cides are degraded by microorganisms in the environ- ment as a source of their limiting nutrients, carbon (C) and/or phosphorus (P). The principal reactions involved in the degradation process are oxidation, hy- drolysis, alkylation, and dealkylation (Singh and Wal- ker, 2006).
