This chapter presents an overview of environmental applications of PLA and other BDPs as the sorbent of HOCs and the substrate for microbial redox processes. In particular, it highlights BDP-based solid-phase denitrification processes and use of PLA for anaerobic bioremediation of persistent contaminants. 

Degradability of the Solid Substrate An important factor to be considered in use of PLA and other BDPs in the solid-phase denitrification process is their degradability, because this factor directly affects in situ denitrifying activity. Information about the biodegradability, biodegradation.

In a comparison of pore water profiles of red clays and hemipelagic sediments, Sawlan and Murray (1983) showed that Mn and Fe are below the detection limit in the pore waters of red clays, Ni is present in the same concentation as in ocean bottom water and Cu shows a pronounced maximum at the sediment-water interface. In hemipelagic clays, denitrification becomes important and remobilization of Mn and Fe takes place. Ni correlates with Mn in the pore waters suggesting that it is associated with the Mn oxides in the solid phase. Cu is regenerated very rapidly at the sediment-water interface. The diffusive flux of Mn in hemipelagic sediments was determined to be in the range 2,200-...
