Dynamic Behavior of Persistent Organic Pollutants in Soil and Their Interaction with Organic Matter

摘要: Persistent organic pollutants (POPs) pose threat to environment because of their potential for longrange atmospheric transport, bioaccumulation and toxicity. The POPs behave dynamically in the according nature action like volatilization, sorption, desorptin transportation from source production some where. These migrate on air currents warmer regions globe towards colder Polar Regions. Once they reach temperatures condense, precipitate out, are deposited again earth’s surface. Environmental variables temperature, soil pH, moisture have serious effects behavior soil. Inorganic minerals also good interaction with xenobiotics play an important role transformation xenobiotics. manganese iron oxides clay (e.g. smectites containing Fe(III)) well-documented properties promote oxidation a number pollutants. Organic matter is considered most factor limiting availability mobility substantial percentage total amount contaminant applied may become associated humic fraction that strongly adsorb carbonaceous sorbents such as black carbon. In particular, activated charcoal (AC) known strong adsorptive capacity due its high specific surface area. Adsorption can render hazardous soils sediments less available organisms hinder dispersal into unaffected environments. Some studies show natural materials, peat, soybean stalk pine needle under superheated temperature/ pressure conditions, sorption polycyclic aromatic hydrocarbons (PAHs) contaminated soils. Natural materials significantly decrease extractability bioavailability PAHs Main objective this review article compile valuable information regarding existence, dynamic behavior, effect environmental interactions matter.
