The aim of this paper is to assess the water quality from several lakes in Rodnei Mountains National Park, in order to establish the extent to which the anthropic activities, such as livestock and tourism affect the water characteristics. The paper presents the quality status of 13 water samples, collected from different mountain lakes from Romania, by monitoring 25 quality indicators, 21 metals and metalloids. The results indicate relatively high content of NH (0.96 mg/L), NO (0.240 mg/L), Ca (38.44 mg/L), Mg (4.35 mg/L), Fe (288 mg/L), Cu (34.46 μg/L) and high values for turbidity (5.31 NTU), chemical oxygen demand (10.00 mgO/L) and suspended materials (88.0 mg/L). Microbiological analyses were performed for 14 types of bacteria. In some samples, the faecal coliforms (1100 bacteria/mL), faecal streptococci (39 bacteria/mL) and aerobic heterotrophic bacteria at 37 °C (300 bacteria/mL) were relatively in a high content. The metal pollution indices (heavy metal pollution index -HPI, heavy metal evaluation index -HEI and the degree of contamination -C) indicated as well that the water samples presented no metal pollution. Values ranged from 5.17 to 27.84 for HPI, 0.55 to 5.07 for HEI and -8.45 to -3.93 for C were obtained. The water quality index (WQI) indicated excellent and good quality for the studied samples, with a mean of 22.6 and a range from 11.4 to 46.9.
本文旨在评估罗德里内山脉国家公园内的几个湖泊的水质，以确定牲畜和旅游等人为活动对水质特征的影响程度。本文介绍了从罗马尼亚不同山区湖泊采集的 13 个水样的质量状况，通过监测 25 个质量指标、21 种金属和类金属来监测水样的质量状况。结果表明，水样中 NH（0.96mg/L）、NO（0.240mg/L）、Ca（38.44mg/L）、Mg（4.35mg/L）、Fe（288mg/L）、Cu（34.46μg/L）的含量相对较高，浊度（5.31NTU）、化学需氧量（10.00mgO/L）和悬浮物（88.0mg/L）值较高。对 14 种细菌进行了微生物分析。在一些样本中，粪大肠菌群（1100 个细菌/mL）、粪链球菌（39 个细菌/mL）和 37°C 需氧异养菌（300 个细菌/mL）的含量相对较高。金属污染指数（重金属污染指数 -HPI、重金属评价指数 -HEI 和污染程度 -C）也表明水样没有金属污染。HPI 值范围为 5.17 至 27.84，HEI 值范围为 0.55 至 5.07，C 值范围为-8.45 至-3.93。水质指数（WQI）表明研究样本的水质为优秀和良好，平均值为 22.6，范围为 11.4 至 46.9。
