Coumaphos

Compounds with organophosphate moieties, such as Diazinon, Methyl Parathion, Coumaphos and Glyphosate are usually hydrolyzed at the phosphoms atom (40,58). Indeed several Flavobacterium isolates are able to grow using parathion and diazinon as sole sources of carbon. 

Organophosphorus pesticides, e.g. coumaphos, menazon, maretin, dursban 200 °C, 45 min Induced fluorescence or amplification of natural fluorescence, detection limits 1-80 ng. [21]... 

After drying in a stream of cold air coumaphos (hRj 30-35) appeared as an intense red chromatogram zone on a colorless background, while parathion methyl (hRj 40-45), fenitrothion (h/ f 45-50) and parathion ethyl (hRf 60-65) yielded yellow zones as they did with sodium hydroxide alone (. v.). The detection limit for coumaphos was 10 ng per chromatogram zone. 

In situ quantitation The absorption photometric scan in reflectance of parathion methyl, fenitrothion and parathion ethyl was carried out at a mean wavelength of 1 )- Coumaphos was determined at X = 540 nm (Fig. IB). 

Fig. 1 Reflectance scan of a chromatogram track with 300 ng each substance per chromatogni zone (A) scan at X = 406 nm, (B) scan at X = 540 nm 1 = coumaphos, 2 = parathion mdli 3 = fenitrothion, 4 = parathion ethyl. ...

Although the inhibition-based biosensors are sensitive, they are poor in selectivity and are rather slow and tedious since the analysis involves multiple steps of reaction such as measuring initial enzyme activity, incubation with inhibitor, measurement of residual activity, and regeneration and washing. Biosensors based on direct pesticide hydrolysis are more straightforward. The OPH hydrolyzes ester in a number of organophospho-rus pesticides (OPPs) and insecticides (e.g. paraoxon, parathion, coumaphos, diazinon) and chemical warfare agents (e.g. sarin) [53], For example, OP parathion hydrolyzes by the OPH to form p-nitrophenol, which can be measured by anodic oxidation.
