Elevated concentrations of dissolved and particulate Cd, Cu, Pb and Zn have been determined in the waters of Kandalaksha Bay (White Sea, Russia), following the ice melt in the spring of 2000. Dissolved metal maxima in the surface waters were observed at some stations and concentrations generally decreased with depth. The suspended particulate matter (SPM) comprised a non-lithogenic fraction in the range 12-83%, and had elevated metal concentrations that showed no trend with depth or salinity and was compositionally distinct from the sediments. A log-linear relationship existed between the concentrations of metals in sediments and in SPM and their respective Al concentrations, indicating a source of metal-rich particles, with low Al content, to the Bay. The results suggest that Kandalaksha Bay has been impacted by industrial activity on the Kola Peninsula and that restricted water exchange will hinder its recovery from metal contamination.
2000年春季融冰之后，在俄罗斯白海的坎达拉克沙湾水域中，已检测出溶解态和颗粒态镉、铜、铅和锌的浓度升高。在一些站点观测到表层水中溶解态金属的最大值，且浓度通常随深度降低。悬浮颗粒物（SPM）中，非岩石成因部分占比在12%至83%之间，其金属浓度升高，且与深度或盐度无关，在成分上与沉积物不同。沉积物和SPM中金属浓度与其各自铝浓度之间存在对数线性关系，表明有低铝含量的富金属颗粒进入该海湾。结果表明，坎达拉克沙湾受到了科拉半岛工业活动的影响，而有限的水交换将阻碍其从金属污染中恢复。
