Biogeochemical cycles estuarine sediments

Burdige, D.J., and Zheng, S. (1998) The biogeochemical cycling of dissolved organic nitrogen in estuarine sediments. Limnol. Oceanogr. 43, 1796-1813. 

Important for understanding factors controlling the biogeochemical cycle of PCBs In the environment more specifically aquatic ecosystems Including estuaries. Our data have demonstrated this for the case of a severely polluted coastal estuarine area, both for the data discussed herein and for pore water, sediment and water column data presented and discussed elsewhere (10, 30). 

Figure 1 Biogeochemical cycles in estuarine and coastal sediments. Particles that fall to the sediment-water interface simultaneously undergo chemical reactions and are mixed through the upper few centimeters of the sediment column. Chemical transformations alter the particles and the sedimentary pore waters surrounding them, driving solute exchange between sediments and the water column and determining the composition of accumulating sediments.
