摘要

提高人口饮用水供应的可靠性和质量是主要的社会问题之一,因为人口的健康在很大程度上取决于饮用水的安全水平。测定哈尔科夫市不同地区居民饮用的泉水的成分,并对不同天然水源的饮用水质量评价进行比较。现场,实验室分析,统计结果。对哈尔科夫市5个天然泉水的水样进行了研究,人们从这些泉水中取水供饮用。根据感官指标确定,除了“Nemyshlianske”来源的样品外,没有观察到超标的正常值,pH值几乎没有季节性变化。秋季总碱度分析结果显示,只有云寺公园及沿街水源样本的总碱度超标。而在春天时期——只有在采样的来源上的街道。Klochkivska。样品的总硬度在秋季为4.9 ~ 8.04 mmol/dm3,春季为6.6 ~ 10.4 mmol/dm3。在所调查的水样中均未观察到氯化物含量超标。只有内米什良斯克泉的水样铁含量超过了MPC水平。样品中铝、锌、镉、铜、铅、氨和亚硝酸盐的含量显著低于MPC水平,且几乎不随季节变化。部分非集中供水水源的总碱度、总硬度和铁含量高,对天然水源水样一般质量等级的形成有显著影响。根据秋季自然水源“Nemyshlyanske”、“Yunist”公园和沿街水样的整体生态指数。Klochkivska属于II级水质,即纯净水。其他水样在秋季的综合生态指数将这些水源分配给I类水质-非常干净。各天然水源地春季水样的综合生态指数计算均为II类水质。

Assessment of the drinking water quality from natural sources in the Kharkiv city
Improving the reliability and quality of the population's drinking water supply is one of the primary social problems, since the health of the population largely depends on the level of safety of drinking water. Purpose. To determine the composition of spring drinking water consumed by residents of different districts of the city of Kharkiv and to compare the assessment of the quality of drinking water from different natural sources. Methods. Field, laboratory-analytical, statistical. Results. Water samples from 5 natural springs in the city of Kharkiv, from which the population collects water for drinking purposes, were studied. It was determined that according to the organoleptic indicators, no excesses of the normative values are observed, the pH almost does not change seasonally, with the exception of the sample from the "Nemyshlianske" source. The analysis of total alkalinity in the autumn period showed that the standard was exceeded only in samples of the source of the Yunist park and along the street. Klochkivska, and in the spring period - only in the sample of the source on the street. Klochkivska. The total hardness in the samples ranges from 4.9 to 8.04 mmol/dm3 in the autumn period, and from 6.6 to 10.4 mmol/dm3 in the spring period. Excesses in chloride content are not observed in any of the investigated water samples. The iron content exceeds the MPC level only in water samples from the Nemyshlianske spring. The content of aluminum, zinc, cadmium, copper, lead, ammonia and nitrites in the samples is significantly below the MPC level, and almost does not change by season. Conclusions. The formation of the general quality class of water samples from natural sources is significantly influenced by the high level of total alkalinity, total hardness, and iron content in some sources of non-centralized water supply. According to the integral ecological index of water samples in the autumn period from natural sources "Nemyshlyanske", Park "Yunist" and along the street. Klochkivska belongs to the II quality class, i.e. pure water. The integrated ecological index for all other water samples in the autumn period assigns these sources to the I class of water quality - very clean. The calculation of the integral ecological index for water samples from all natural sources in the spring period refers them to the II quality class.
