    Trees and Environmental Remediation


    This presentation is designed to highlight the importance of tree species in remediating soil, water, and air pollution. Tree species are capable of containing, degrading, or eliminating metals, pesticides, solvents, explosives, crude oil and its derivatives and various other contaminants from the media that contains them. The following components will be discussed. 

    ·        U ptake and concentration of substances from the environment into the tree biomass.

    ·        Reduction of the mobility of substances in the environment, for example, by limiting the leaching of substances from the soil.

    ·        Enhancement of soil microbial activity for the degradation of contaminants, typically by organisms that associate with roots.    

    ·        Removal of substances from soil or water with release into the air, sometimes as a result of transformation to more volatile and/or less polluting substances.

    ·        Filtering water through a mass of roots to remove toxic substances or nutrients. The pollutants remain absorbed in or adsorbed to the roots.

    Arboricultural and urban forestry practices to increase remediation and mitigation capacity of tree species will be highlighted and discussed.
