Abstract: Nitrofen ( 2,4 dichlorophenyl - 4 - nitro phenylether ) , is a herbicide used for the control of weeds in rice and onion fields . The Transformation of nitrofen at the site of application is of great intrest to safeguard the enviroment against chemical pollution with repeated application of this herbicide.
The metabolism and co-metabolism of nitrofen by soil micro-organisme was studied.
Chromotagraphic separation revealed the presence of p-nitro-phenol, p-aminophenol, p-quinone and 2,4- dichlorophenol as the major intermediates in nitrofen soil leachate cultures.
It is concluded that the initial step in nitrofen metapolism is the hydrolysis of the ether linkage to give rise to p-nitrophenol and 2,4-dichlorophenol.
P-Nitrophenol is converted to p-aminophenol befor hydroxylation to quionl which is oxidized by ring fission. 2,4, dichlorophenol resulted from the hydrolysis is also oxidized by ring fission through khown metabolic pathways.
The above results indicates that nitrpfen is only of short persistence and is not cause any chemical pollution problems.
