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 NH4+ (0.96 mg/L), NO2- (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 mgO2/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 -Cd) 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 Cd 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.

人为活动对罗马尼亚罗德奈山冰川湖水质参数的影响。

本文的目的是评估罗德奈山国家公园中几个湖泊的水质，以便确定诸如牲畜和旅游业等人类活动对水质的影响程度。本文通过监测25个质量指标，21种金属和准金属，介绍了从罗马尼亚不同山区湖泊收集的13种水样品的质量状况。结果表明NH4 +（0.96 mg / L），NO2-（0.240 mg / L），Ca（38.44 mg / L），Mg（4.35 mg / L），Fe（288 mg / L），Fe（288 34.46μg/ L）和高浊度（5.31 NTU），化学需氧量（10.00 mgO2 / L）和悬浮物（88.0 mg / L）的高值。对14种细菌进行了微生物分析。在一些样品中，粪大肠菌群（1100个细菌/ mL）粪便链球菌（39细菌/ mL）和好氧异养细菌在37°C（300细菌/ mL）含量相对较高。金属污染指数（重金属污染指数-HPI，重金属评估指数-HEI和污染程度-Cd）也表明水样品没有金属污染。获得的值的范围从HPI的5.17至27.84，HEI的0.55至5.07和Cd的-8.45至-3.93。水质指数（WQI）表明所研究样品的优良品质，平均值为22.6，范围为11.4至46.9。重金属评估指数-HEI和污染程度-Cd）也表明水样品没有金属污染。获得的值的范围从HPI的5.17至27.84，HEI的0.55至5.07和Cd的-8.45至-3.93。水质指数（WQI）表明所研究样品的优良品质，平均值为22.6，范围为11.4至46.9。重金属评估指数-HEI和污染程度-Cd）也表明水样品没有金属污染。获得的值的范围从HPI的5.17至27.84，HEI的0.55至5.07和Cd的-8.45至-3.93。水质指数（WQI）表明所研究样品的优良品质，平均值为22.6，范围为11.4至46.9。
