Additionally, it has been demonstrated that some earthworms are able to increase metal uptake by plants, thus increasing the metal availability, one of the main limitation of phototypesetting, thereby improving efficiency of petrifaction (Went et al. , 2004). The obtaining organisms studied in this work were deficit worms, are one of the major botheration agents in freshwater environments (Fisher et al. 1980). According to Cunningham (1999), difficult are small burrowing worms often about 2-5 CM long and roughly 1 mm in diameter when fully mature.

By feeding its head down in muddy sediments, consuming sediments at depth and depositing undigested material at the sediment-water interface, they could lead to downward sediment migration. Such sediment could be recycled through the feeding zone many times before ultimate burial below the deepest feeding zone (Motifs et al. , 1999). Deficit has a major effect on exchange Of redo-sensitive species across the sediment?? water interface y its metabolism on prevention of the establishment of an OIC layer at the top of the sediment (Inasmuch et al. , 2012).

Under botheration conditions, Cadmium is trapped within the surface layers of sediments (few millimeters from the surface) on the manganese and iron oxides, and then is transferred into the depth layer via beatification (S. Dolomite et al. , 2007). Deficit worms which are one of the major botheration agents in freshwater environments are studied in this work as the obtaining organisms (Fisher et al. , 1980). According to finding of Cunningham (1999), difficult are ascribed as small burrowing worms which are often about 2-5 CM long and roughly 1 mm in diameter when fully mature.

The deficit could lead to downward sediment migration if its head is fed in muddy sediments, consuming sediments at depth and depositing digested material at the sediment-water interface. Through the feeding zone, such sediment could be recycled many times before ultimate burial below the deepest feeding zone (Motifs et al. , 1999). By its metabolism on prevention of the establishment of the OIC layer at the top of the sediment, deficit has a significant effect on exchange of redo-sensitive species across the sediment-water interface. (Inasmuch et al. , 2012).

Cadmium is caught within the surface layers of sediments (few millimeters from the surface) under botheration conditions, and then via beatification is transferred into the depth layer (S. Demote et al. , 2007). Until now, although understandings of obtaining mechanisms on metal availability in the water-sediment condition are considerable, investigations of botheration application on phototypesetter have not been performed thoroughly. Thus, a combination between abattoir invertebrate worms) and a specific aquatic plant in the environmental restoration (petrifaction) in this study could be considered as a first examination.

It is, therefore, not easy and inappropriate for the first test to work with the whole natural communities of invertebrate and plants so that we selected model species that are known to be active in botheration and petrifactions. This investigation aims to address the question: Does fasciculation of pollutants by aquatic plants increase (or decrease) by sediment botheration under benthic invertebrate activity? This hypothesis ill be tested in microcosms that reproduce each a portion of water/sediment interface of pounds.

Comparison of pollutant fasciculation in plants with and without botheration will allow estimating the influence faunal biodiversity in the premeditation process. Expected results will be pollutants fluxes through both major interfaces water/sediment and sediment/plants from estimation of the pollutant concentrations in each compartment: water, sediment and plant. If botheration favored the burial and bio-accessibility of the pollutant in the sediment, the plant petrifaction should be optimized in aquariums with maximum biodiversity.
