Organic geochemistry of water and bottom sediments during a seasonal flood in 2006 in the North Dvina River estuary, supplement to: Nemirovskaya, Inna A (2011): Distribution of hydrocarbons in the estuarine area of the Northern Dvina River during seasonal flood. Geochemistry International, 49(8), 815-826
Heavy contaminant load released into the Northern Dvina River during flooding increased the concentrations of aliphatic (AHC) and polcyclic aromatic (PAH) hydrocarbons in water and bottom sediments. The composition of hydrocarbons was different from that of the summer low flow season. The concentrat...
