Emet River Basin is a worldwide significant mining area and contains the most important boron and chromium deposits of Turkey. In this study, water and sediment quality of Emet River Basin was evaluated using some toxic element risk assessment indices. Samples were collected seasonally from 8 locations and nickel (Ni), chromium (Cr), arsenic (As), zinc (Zn), lead (Pb), copper (Cu) and cadmium (Cd) accumulations in water and sediment were analysed using an ICP-OES. Water Quality Index (WQI), Heavy Metal Pollution Index (HPI), Heavy Metal Evaluation Index (HEI) and Degree of Contamination Index (C_deg) were applied to the data for assessing the water quality and Biological Risk Index (BRI), Potential Ecological Risk Index (PERI), Geo-Accumulation Index (I_geo), Contamination Factor (CF) and Pollution Load Index (PLI) were applied to the data for assessing the sediment quality. According to the results of WQI, HPI, HEI and C_deg, As and Cr were recorded as the most dangerous toxicants; according to the results of BRI, I_geo, CF and PLI, Cd, As and Pb were recorded as the most dangerous toxicants; and according to the results of PERI, Ni and Cr were recorded as the most dangerous toxicants among the investigated elements. The seasonal average values of applied ecological indices for the water of the basin ranged 71.41–888.29 for WQI, 85.97–915.76 for HPI, 4.04–49.80 for HEI and − 2.95–42.80 for C_deg. The seasonal average values of applied ecological indices for the sediment of the basin ranged 33.72–130.56 for PERI, 0.14–0.93 for BRI, − 3.92–5.99 for I_geo and 0.45–1.20 for PLI. In addition to the intensive agricultural applications around the region, the geological structure of the watershed was considered as the main cause of the high heavy metal accumulations in basin waters and sediments.

埃梅特河流域是世界范围内重要的采矿区，蕴藏着土耳其最重要的硼和铬矿床。在这项研究中，使用一些有毒元素风险评估指标对埃梅特河流域的水和沉积物质量进行了评估。季节性地从8个地点采集样品，并使用以下方法分析了水和沉积物中的镍（Ni），铬（Cr），砷（As），锌（Zn），铅（Pb），铜（Cu）和镉（Cd）积累ICP-OES。将水质指数（WQI），重金属污染指数（HPI），重金属评估指数（HEI）和污染度指数（C _deg）应用于数据，以评估水质和生物风险指数（BRI），潜力生态风险指数（PERI），地缘累积指数（I _geo），污染因子（CF）和污染负荷指数（PLI）应用于评估沉积物质量的数据。根据WQI，HPI，HEI和C _deg的结果，As和Cr被记录为最危险的毒物。根据BRI的结果，我_地理，CF和PLI，镉，砷和铅记录为最危险的毒物; 根据PERI的结果，Ni和Cr被记录为被调查元素中最危险的毒物。流域水的应用生态指数的季节平均值在WQI范围为71.41–888.29，HPI为85.97–915.76，HEI为4.04–49.80，C_度为− 2.95–42.80。流域沉积物应用生态指数的季节平均值范围为：PERI为33.72–130.56，BRI为0.14–0.93，I _geo为−3.92–5.99，PLI为0.45-1.20。除了该地区密集的农业应用外，流域的地质结构还被认为是盆地水体和沉积物中大量重金属积累的主要原因。
