Diazinon is Diazinon volatilizes into the air at room temperature. A The major environmental degradate of diazinon is diazoxon, which rapidly hydrolyzes to oxypyrimidine under most circumstances. Diazinon breakdown is faster at warmer water temperatures, degrading 2-4 times faster in water at 21 °C compared to Diazinon is a bit different - its breakdown product is MORE toxic than the original molecule (higher mammalian toxicity!). Ultimately, diazinon applied to soils is broken down to carbon dioxide. Any help on this question would be greatly appreciated! populations.
