Abstract LI1ere iL’•c· .lciJC:, L<’\,eractllle; lactors wnJ.ch influence the activi·ty :wl .toeT”Giscence of pesticides iL soils. A brief review of these would include soil pE, soil texture, organic naLtel”, cation exchange, pre!valent cacions or other 1;;:L’lerals, chemical reactions 1 and mechanical analysis, Environmental factors such as temperature, moistun;, leach:D1g1 sunlight, microbial activity, plant growth and rizosphere are also highly important. The physical and chemical characteristics of the pesticide itself determine hou it responds to all the above factors. fi1uch of the research on nonbiologlical detoxication has been conce:nt:;.”ated on photodecomposition, volatilization, soil adsorption 2~d two soil associated chemical reactions: hydroxylation and dealkylation. In addition, codistillation has been suggested as a possible mechanism for loss of pesticide activity (S-triaz:D1e)·. Since biological an.d nonbiolof;ical reactions are both chemical in nature, the same corT’e.latious would be expected between soil properties and t11eir microbially-catalyzed decOI:Jposition or detoxication reactions occurriilc in the absence of aY.ij/ biolor.:ic.:aJ_ ;~ent.
