Abstract

Monitoring and assessment of surface drinking water resources is vital for human life. As it is known, many diseases are caused by contaminated waters. Surface water resources quality was classified in terms of treatment potential by using 41 conventional parameters in Turkey. It is not insufficient to take these conventional parameters into account alone due to the fact that there exist new developments in application of varying level of different chemicals generated as part of daily activities. The main objective of this study is to recommend some changes for the water resources quality classification of Turkey by investigating the No Observed Adverse Effect Limit (NOAEL) and Lowest Observed Adverse Effect Level (LOAEL) classifications of different pollutants. These pollutants are associated with highest and lowest doses at which there was not an observed toxic or adverse effect, respectively. This new evaluation scheme will allow integration of new pollutants, i.e., micropollutants, and monitoring as per the findings of this study. A detailed site-specific monitoring was also undertaken by collecting samples from 283 of surface water locations at four times during the year across Turkey. The results obtained in this study indicate that, even if there is a pressure in terms of micropollutants in surface water resources of Turkey, the problem in terms of conventional parameters are more dominated and the water quality problems in Turkey have been exacerbated in terms of microbiological indicators such as total coliform, fecal coliform and fecal streptococcus. It is also important to note that the heavy metal concentrations originated from the site-specific geological formation were detected in the surface drinking water resources of Turkey.

根据水质标准评估土耳其地表饮用水资源

摘要

监测和评估地表饮用水资源对人类生命至关重要。众所周知，许多疾病是由水污染引起的。通过使用土耳其的41个常规参数，根据处理潜力对地表水资源质量进行了分类。仅仅考虑这些常规参数是不够的，这是由于在日常活动中产生不同水平的不同化学物质的应用存在着新的发展。这项研究的主要目的是通过调查不同污染物的无观测不利影响限值（NOAEL）和最低观测不利影响水平（LOAEL）分类，为土耳其的水资源质量分类提出一些建议。这些污染物分别与最高剂量和最低剂量有关，在这些剂量下没有观察到毒性或不利影响。根据本研究的结果，这种新的评估方案将允许整合新污染物（即微污染物）并进行监测。通过在整个土耳其一年中四次收集来自283个地表水位置的样本，还进行了针对特定地点的详细监控。这项研究获得的结果表明，即使在土耳其地表水资源中存在微量污染物的压力，传统参数方面的问题仍占主导地位，并且土耳其的水质问题在微生物学方面也加剧了指标，如总大肠菌群，粪便大肠菌群和粪便链球菌。
