Abstract

The concentrations of Fe, Mn, Cu, Zn, Pb, Cd, and Ni were studied in the brown algae Sargassum miyabei Yendo and S. pallidum (Turner) C. Agardh collected in Ussuri Bay, Sea of Japan, from 2001 to 2018. The degree of heavy metal pollution in different parts of the bay was assessed by comparing the actually measured concentrations of the metals in algae with the upper threshold values of their background ranges of concentrations (C_UT). The coefficient of metal contamination risk for algae (K_R) was calculated as the ratio of the metal concentration in algae to C_UT. In 2016–2018, the K_R values for Cd and Ni reached 1.7; for Zn, 2.0; for Fe, 3.1; for Mn, 7.2; for Pb, 12.3; and for Cu, 15.0. The maximum concentrations of most elements were recorded from the Sargassum algae collected off the Vladivostok municipal solid waste landfill operated in 1967–2010. In this part of the bay, the major pollutants in 2016–2018 were Pb and Cu; the accompanying pollutants were Zn, Mn, Fe, and Ni.

日本海乌苏里湾重金属污染的长期生物监测

摘要

研究了2001 年至 2018 年在日本海乌苏里湾采集的褐藻Sargassum miyabei Yendo 和S. pallidum (Turner) C. Agardh中 Fe、Mn、Cu、Zn、Pb、Cd 和 Ni 的浓度。通过将藻类中实际测量的金属浓度与其背景浓度范围 (C _UT )的上限阈值进行比较，评估了海湾不同部分的重金属污染程度。藻类金属污染风险系数（K _R）计算为藻类中金属浓度与C _UT的比值。2016-2018 年，K _RCd 和 Ni 的值达到 1.7；对于锌，2.0；对于铁，3.1；对于锰，7.2；对于 Pb，12.3；对于铜，15.0。大多数元素的最大浓度是从1967-2010 年运营的符拉迪沃斯托克城市固体垃圾填埋场收集的马尾藻藻类中记录的。该湾区2016-2018年主要污染物为Pb、Cu；伴随污染物为锌、锰、铁和镍。
