Original Title:
Προσδιορισμός αναδυόμενων ρύπων σε υπόγεια και πόσιμα ύδατα της λεκάνης του Ασωπού ποταμού με τεχνικές φασματομετρίας μάζας υψηλής διακριτικής ικανότητας
Translated title:
Determination of emerging contaminants in drinking water and groundwater of Asopos river basin with high resolution mass specrometry
Summary:
The present thesisfocuses on the analysis of emerging pollutants in drinking and groundwater samples taken as part of a larger survey entitled: and qualitative and quantitative investigation of its origin and scope / levels ", a project funded by the Attica Region.
Although the safety of modern treated water networks is usually taken for granted, cases of pollutioncan occur at various stages of drinking water production. Natural reservoirs from which water is withdrawn and sent to treatment plants can be contaminated with a variety of pollutants. Such cases of infection must be properly addressed through drinking water treatment procedures so that low quality water is not transferred to the consumer. A complete risk analysis is therefore an urgent need to identify critical points in the drinking water treatment and production process in order to minimize the risks. Infected groundwater is less visible and more difficult to clean from pollution in rivers and lakes. Groundwater pollution is usually the result of improper disposal of waste on land and is often withdrawn for agricultural, municipal and industrial use by constructing and operating mining wells. That is why their quality must be controlled and monitored, especially if the mining sites are very close to industrial areas, such as that of the Asopos river basin.
In order to monitor the quality of these waters, analysis will be performed by high performance and resolution instruments (HRMS) and in particular liquidand gas chromatography will be used in conjunction with a high resolution mass analyzer (UHPLC-QTOF, GC-APCI-QTOF) .
