This thesis can be divided into two major parts. The first was concerned with the environmental fate of the dinitroaniline herbicide trifluralin, in which the dissipation of this pesticide in the environment, in general, was reviewed and the two most important pathways of trifluralin dissipation were studied. These two pathways are volatility and photodecomposition (Chapters 2 and 3 respectively). The study on the volatility of trifluralin from soil included the development of an analytical method suitable for the analysis of trifluralin in the treated soil headspace. The analytical method required the preconcentration of trifluralin vapours on an adsorbent trap (Tenax) followed by thermal desorption of the trifluralin vapours into a gas chromatograph to achieve a sensitive detection method. The Tenax trap was found to be very efficient at trapping trifluralin vapours with a high recovery which ranged from 92.3 q 2 0 to 98.3 q 1.4. The effect of storage conditions on the recovery of the trapped chemical was also investigated and it was found that the trapped sample of trifluralin could be stored at 5
