“…Pentachloroaniline and methyl pentachlorophenyl sulfide have also been detected in young corn and soybean plants grown in soil treated with PCNB. In addition, PCA had been identified previously by Gorbach and Wagner (1967) as a metabolite in potatoes. These investigators also indicated the presence of unidentified metabolites in addition to PCA at relative retention volumes of 0.9 and 1.8.…”

Tissues from beagle dogs fed Terraclor in foodThe presence of PCA and methyl pentachloro-(PCNB, daily for up to two years) were analyzed by phenyl sulfide has been established by infrared and gas chromatography for residual PCNB, impurities, mass spectroscopy. Chromatographic analyses of and metabolites. The data obtained are indicative extracts of rat tissues from rats fed PCNB and from that PCNB is not present in fat or tissue and the plants grown in PCNB treated soil are indicative of metabolic products of PCNB are pentachloroa n identical metabolism. aniline (PCA) and methyl pentachlorophenyl sulfide. erraclor, or pentachloronitrobenzene (PCNB), manufactured and sold by Olin Mathieson Chemical Corpo-T ration as a soil fungicide, was incorporated in animal food and fed daily to beagle dogs and rats in a two-year chronic test conducted at the Medical College of Virginia.The animal tissues. as well as the excretion products, were anal) zed b> gas chromatography employing electron capture detection for PCNB, impurities such as hexachlorobenzene (HCB), pentachlorobenzene (PCB), and metabolites of PCNB.The metabolism products of PCNB in plants were followed b). anal).zing young plants grown in soil treated with PCNB.

“…Positive identification of PCA and the metabolite a = 2.0 in extracts of dog feces was attempted by employing thinlayer chromatographic techniques by an essentially identical procedure to that of Gorbach and Wagner (1967). Zones on the thin-layer plate were qualitatively established by UV fluorescence and the material was removed with hexane.…”

“…Both PCA and PCTA appear to be end products with no further degradation. These products would presumably remain in the soil as residues, unless absorbed by plants (Gorback and Wagner, 1967;Kuchar et al, 1969). Conversion to PCP with subsequent further degradation of PCP (Murthy and Kaufman, 1978) would seem to be the only pathway by which PCNB is more completely degraded.…”

“…The significance of PCNB residues in the environment is not fully understood. Gorback and Wagner (1967) investigated PCNB residues in potatoes grown in PCNB-treated soil and detected PCNB, PCA, and one unidentified metabolite in the potato peel. Both PCA and the unidentified metabolite, but not PCNB, were also found in the inner potato tissue.…”

The Concentrations of organophosphorus pesticide residues (dichlorvos, diazinon, chlorpyrifos, and fenitrothion) were determine in some vegetables (spinach, lettuce, cabbage, tomato and onion) and soil samples from different depths within Alau Dam and Gongulong agricultural areas in Borno State, Nigeria. Samples collection and preparation were carried out using standard procedures. The concentrations of all the pesticides in the vegetables and soil samples were determined using GC/MS SHIMADZU (GC-17A) equipped with electron capture detector (ECD). The highest concentrations of diclorvos, diazinon, chlorpiryfos and fenithrothion in the Alau Dam and Gongulong agricultural areas were observed in the leaf of tomato, while the lowest concentrations were observed in the root of spinach. The concentrations of all the pesticides in the soil samples were observed to be higher at a depth of 21-30cm, while the lowest concentrations were observed at a depth of 0-10cm. The concentrations of all the organophosphorus pesticides in the vegetables and soil samples from the two agricultural areas were observed to be at alarming levels, much higher than the maximum residue limits (MRLs) and acceptable daily intake values (ADIs) set for vegetables and soil by the Cordex 2009 (WHO and FAO). The occurrence of pesticides in the vegetables and soil samples is a major threat to human that depends on these vegetables as food. Hence, the need for continuous monitoring is recommended so as to regulate the used of this pesticide in the study areas.
