| Abstract/Contents: | "Once pesticides and transgenic crop toxins are introduced into the environment, physical, chemical, and biological processes cause the chemicals to be transferred from place to place and transformed to reaction products. Five transfer processes are normally involved: 1) Absorption, exudation and retention by plants and plant residues; 2) Adsorption and desorption by colloidal soil surfaces; 3) Movement over the soil surface in runoff water in the dissolved or bound state; 4) Vapor-phase diffusion through soil pores and the atmosphere; and 5) Hydrodynamic transport through the aqueous phase of the soil media. Three transformation processes may be involved: 1) Photochemical degradation by sunlight; 2) Chemical degradation such as hydrolysis; and 3) Biological degradation by plants and microorganisms. Dissipation of herbicides and toxins is governed by four major elements, namely, 1) Physicochemical properties of the compound; 2) Soil properties; 3) Application conditions and time of application; and 4) Climatic and hydrogeologic conditions. Herbicides and transgenic crop toxins should persist and be mobile enough to control the target pest but not other species and not contaminate the air, water or soil. A ranking of 15 herbicide products used by the North Carolina Department of Transportation for environmental and toxicological safety is included." |
