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. [Pg.175]

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). [Pg.175]

Very little information exists in the literature on the transformation and degradation of methyl parathion in air. An early study indicated that direct photolysis of methyl parathion may occur however, the products of this photolysis were not determined (Baker and Applegate 1974). A later study found a transformation product of methyl parathion, methyl paraoxon, in air samples taken from areas where methyl parathion had been applied. Formation of methyl paraoxon was attributed to the vapor phase oxidation of methyl parathion (Seiber et al. 1989). Recent monitoring studies in California have also found both methyl parathion and methyl paraoxon (Baker et al. 1996). [Pg.153]

A study of estuarine fish in 21 coastal states conducted from 1972 to 1976 as part of the National Pesticide Monitoring Program detected a mean concentration of 47 ppb in 3.9% of the fish tissue samples collected (Butler and Schutzmann 1978). In another study (Cooper 1991), fish collected in a watershed area of Mississippi were analyzed for residues of methyl parathion. Methyl parathion was detected in seven species of fish, with white bass having the greatest mean concentration, at 15.96 ppm. Methyl parathion was found in 3 of the 32 fish samples collected before spraying of methyl parathion and in 12 of the 25 samples of fish collected after methyl parathion spraying. [Pg.161]

Samples of the indoor and outdoor air at the homes of workers occupationally exposed to pesticides, farmers and pesticide formulators, were taken monthly and analyzed for methyl parathion. Methyl parathion was found in 13 of 52 indoor air samples of formulators homes at a mean concentration of 0.26 pg/m (range of 0.04-9.4 pg/m ). Outdoor air samples of formulators homes showed that 3 of 53 samples contained methyl parathion at concentrations ranging from 0.15 to 0.71 pg/m. Methyl parathion was not detected in the indoor and outdoor air samples from farmers homes (Tessari and Spencer 1971). [Pg.163]
