Vertical variations of radionuclides, trace metals, and major elements were determined in two sediment cores, which were collected in the marine environment of Ierissos Gulf near Stratoni's mining area. The enrichment factors (EFs) were also estimated and provided moderately severe to extremely severe enrichment for most trace elements and Mn, describing the anthropogenic influence in the gulf during the previous century. According to the applied dating models based on Pb and Cs, the effect in the marine sediment due to the exploitation of pyrite for the production of sulfuric acid during 1912-1920 was observed. Additionally, the decrease of mining activity during 1935-1945 due to the Second World War and the type of ore exploitation, the alteration of the exploited ores, and the construction and operation of Olympiada's floatation plant during 1950-1970 were identified. The end of tailing discharging into the marine environment during 1980-2010 was also noted.
在斯特拉托尼(Stratoni)矿区附近的伊雷索斯湾(Ierissos Gulf)的海洋环境中采集了两个沉积物岩芯,测定了其中放射性核素、微量元素和主要元素的垂直变化。还估算了富集因子(EFs),大多数微量元素和 Mn 的富集因子为中度至极度富集,表明在过去一个世纪里,海湾受到了人为影响。根据基于 Pb 和 Cs 的应用定年模型,观察到 1912-1920 年开采黄铁矿生产硫酸对海洋沉积物的影响。此外,1935-1945 年由于第二次世界大战以及矿石开采类型、已开采矿石的变化,以及 1950-1970 年奥林匹亚浮选厂的建设和运营,采矿活动减少。还注意到 1980-2010 年尾矿不再排入海洋环境。
