The objective of this article is to determine the spatial changes occurring because of natural and anthropogenic toxic metal pollution in accordance with different indexes using the geographic information system (GIS) method. In this context, the distribution of toxic metals, i.e., chromium (Cr), copper (Cu), zinc (Zn), lead (Pb), nickel (Ni), and arsenic (As), is investigated using sediment samples from the Hopa Harbor situated in the Southeastern Black Sea region. Sediment samples are collected from nine different stations in June 2017. Metal concentrations (in dry weight) vary from 23.2 to 94.7 for Cr, 62.1 to 301.7 for Cu, 89.3 to 287.9 for Zn, 67.6 to 137.1 for Pb, 20.1 to 99.1 for Ni, and 14.2 to 57.4 µg g−1 for As. The samples with highest concentrations are situated in the inner part of the harbor, where the water circulation system to remove the impurities is very poor. It is evident that Hopa Port activities negatively affect sediment quality, with metal concentration values increasing at stations close to the port. The data of this study reveal that Cu, Pb, and As are the main contributors to the ecological toxicity in and around Hopa Harbor. However, if the results are evaluated according to the longer time series, more precise data on the toxic effects of metals can be obtained.

土耳其霍帕港附近沉积物中的有毒金属污染和生态风险估算

本文的目的是使用地理信息系统(GIS)方法,根据不同的指标确定由于自然和人为有毒金属污染而发生的空间变化。在这种情况下,使用沉积物中的沉积物样本研究了有毒金属的分布,即铬(Cr),铜(Cu),锌(Zn),铅(Pb),镍(Ni)和砷(As)。霍帕港位于东南黑海地区。2017年6月从9个不同站点收集了沉积物样本。金属的浓度(以干重计)从Cr的23.2至94.7,Cu的62.1至301.7,Zn的89.3至287.9,Pb的67.6至137.1,Ni的27.1至99.1。和14.2至57.4 µg g -1对于作为。最高浓度的样品位于港口的内部,用于去除杂质的水循环系统非常差。显然,霍帕港的活动对沉积物质量产生了负面影响,靠近港口的站点的金属浓度值增加。这项研究的数据表明,铜,铅和砷是霍帕港及其周边地区生态毒性的主要贡献者。但是,如果根据较长的时间序列评估结果,则可以获得有关金属毒性作用的更精确的数据。
