Once a chemical enters the soil it is subject to various transformation processes. It partitions between the liquid, solid and gaseous phase, it is sorbed to different binding sites with a different strength of bonding, it may decay by a simple chemical process or it may be transformed by microorganisms. Solute transport through soil and subsurface is mediated by water flow and is strongly influenced by solute sorption. To complicate matters, soil structures are heterogeneous. All these processes are embedded in 606 $aPesticides$xEnvironmental aspects$xMathematical models 606 $aDynamics 615 0$aPesticides$xEnvironmental aspects$xMathematical models. 615 0$aDynamics. 676 $a363.7396 676 $a577.279 700 $aRichter$b O$g(Otto)$0333139 701 $aDiekkru?ger$b B$g(Bernd)$01341321 701 $aNo?rtersheuser$b P$g(Peter)$01341322 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a996198802103316 996 $aEnvironmental fate modelling of pesticides$93063770 997 $aUNISA
