Witryna1 lut 2009 · This study focused on two specific goals: (i) to estimate natural concentrations of Hg 0 in lake sediments; (ii) to evaluate the effect of oxygen concentration, pH, particle size and organic matter content on Hg 0 adsorption in sediments. 2. Experimental 2.1. Site description and sample collection WitrynaBecause wetlands are associated with waterlogged soils, the concentration of oxygen within sediments and the overlying water is of critical importance. The rate of oxygen diffusion into water and sediment is slow, and this (coupled with microbial and animal respiration) leads to near-anaerobic sediments within many wetlands ( Moss, 1998 ).
Witryna15 lip 2024 · Generally, studies have shown that sediment can act both as a sink and important source of N in the aquatic environment (e.g., Chon et al., 2012 and references therein), and plays a crucial role in the biogeochemical cycling of N in lake ecosystem ( Porubsky et al., 2009 ). Witryna6 paź 2024 · Sediment controls the physical habitat of river ecosystems. Changes in the amount and areal distribution of different sediment types cause changes in river-channel form and river habitat.
