摘要
本研究旨在通过综合指数分析法确定奥林湖的生态风险。收集了阿林湖表层沉积物样品21份和基岩样品5份。金属浓度由ICP-OES分析值获得。利用ICP-OES数据计算富集系数(EF)、污染系数(CF)、地质累积指数(Igeo)和毒性风险指数(TRI)、修正生态风险指数(mER)和修正潜在生态风险指数(m-PER)。结果表明:湖区湖区金属元素的平均浓度依次为Al > Fe > Mn > Zn > Ni > Co > Pb > Cd > As。虽然Ni、As和Zn被中度富集，但只有Ni被中度污染。地质累积系数确定为无污染，PER值显示为低生态风险。第二高的EF值属于As，这被认为是源于该地区使用化石燃料。通过对奥林湖的生态风险分析，确定其重金属含量不高，不存在毒性。
Ecological Risk Analysis of Lake Arin Sediments (Bitlis, Türkiye)
This study aimed to determine the ecological risk of Lake Arin through an analysis using comprehensive indexes. Surface sediment samples (21) and bedrock samples (5) were collected from Lake Arin. The metal concentrations were obtained from the ICP-OES analysis values. Enrichment Factor (EF), Contamination Factor (CF), Geoaccumulation Index (Igeo) and Toxic Risk Index (TRI), Modified ecological risk index (mER) and Modified Potential Ecological Risk Index (m-PER) were calculated from the ICP-OES data. Our results reveal that the average concentration of the Lake Arin metals is Al > Fe > Mn > Zn > Ni > Co > Pb > Cd > As, in decreasing order. While moderate enrichment was determined for Ni, As and Zn, moderate contamination was detected only for Ni. It was determined there was no contamination in terms of Geoaccumulation Factor, and PER values showed low ecological risk. The second highest EF value belongs to As, which is thought to originate from the use of fossil fuels in the region. As a result of the ecological risk analysis of Lake Arin, it was determined that the metal levels were not at high levels and were not toxic.
