secondary sedimentation Explanation: Proposition. I do not think this is silting/siltation, which pertain to soil particles. Siltation is the pollution of water by particulate terrestrial clastic material, with a particle size dominated by silt or clay. It refers both to the increased concentration of suspended sediments, and to the increased accumulation (temporary or permanent) of fine sediments on bottoms where they are undesirable. cccccccccc -------------------------------------------------- Note added at 38 mins (2016-02-27 15:39:12 GMT) -------------------------------------------------- Treated wastewater effluent from Las Vegas, Nevada and surrounding communities' flow through Las Vegas Wash (LVW) into the Lake Mead National Recreational Area at Las Vegas Bay (LVB). Lake sediment is a likely sink for many hydrophobic synthetic organic compounds (SOCs); however, partitioning between the sediment and the overlying water could result in the sediment acting as a secondary contaminant source. http://www.ncbi.nlm.nih.gov/pubmed/22464858 cccccccccccccccc Role of bottom sediments in the secondary pollution of aquatic environments by heavy-metal compounds http://onlinelibrary.wiley.com/doi/10.1046/j.1440-1770.2000.... ccccccccccccccccccccccccccccccccccccccccccccccccc lake, bottom sediments, phosphorus fractions, water mixing, human impact In lakes the bottom sediments are built by mineral and organic substances removed from the water during the processes of precipitation, sorption and sedimentation. They play a significant role in the functioning of the ecosystem, related to the possibility of secondary release of these substances http://www.pjoes.com/pdf/18.6/1093-1099.pdf |
