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 PesticidesEnvironmental aspectsMathematical modelsDynamicsPesticidesEnvironmental aspectsMathematical models.Dynamics.363.7396577.279Richter O(Otto)333139Diekkrüger B(Bernd)1341321Nörtersheuser P(Peter)1341322MiAaPQMiAaPQMiAaPQBOOK9910830961603321Environmental fate modelling of pesticides3063770UNINA01696nam0 22003371i 450 UON0051042120231205105455.233978-88-229-0819-320221206d2022 |0itac50 baitaIT|||| 1||||Archivi espostiteorie e pratiche dell'arte contemporaneaa cura di Massimo Maiorino, Maria Giovanna Mancini, Francesca ZanellaMacerata : Quodlibet2022175 p.22 cmAtti del Convegno online tenuto nel 2021.001UON004832782001 Quaderni dell'Accademia di Belle Arti di Macerata.
