Effect of different disinfection methods on quality of tap water
(Wydawnictwa AGH, 2019) Jachimowski, Artur
This paper specifies the effect of using strong oxidants in water treatment technologies on the formation of disinfection by-products. The study was developed by collecting water samples from four water treatment plants of the Municipal Water and Sewerage Company (MPWiK) in Krakow and at select-ed sampling points within the water supply networks. The analysis was comprised of selected indicators of water quality after the treatment process during the years of 2011-2017. From the carried-out investigation, it was concluded that the concentration of free chlorine in the water supply network concurrently decreased with increases in the distance from the treatment plant. This dependence was found in 19 out of 28 water supply points. While analyzing the annual average concentrations of free chlorine in the municipal water, it was noted that the highest values at the study points occurred in 2011. During the other years, decreases in this indicator were observed. This follows from the analysis that the water disinfection by-products did not exceed permissible limits.

Investigating the content of microplastics and other extraneous particles in Polish bottled water
(Wydawnictwa AGH, 2023) Aleksander-Kwaterczak, Urszula; Gaj, Dominika; Stelmach, Alex; Wróbel, Tomasz P.
Bottled water has enjoyed a global increase in popularity since it is generally perceived to be superior in quality to tap water and necessary when tap water is non-potable. As a result, ensuring that it meets the requisite quality standards is of vital importance. This work aims to examine the content of solid particles, including microplastics, in bottled water available in Polish stores. The second aspect is the preliminary determination of the influence of the water gassing process, together with thermal and light factors, on the content of particles in the water. The number of particles was counted by colour and shape, with the number ranging from 87 to 188 per litre of water, on average, there were 136 $\pm$ 32 particles per litre of water, demonstrating that water from disposable plastic bottles is contaminated with various substances. The difference in the number of particles may be due to the origin of the waters, the processes they were subjected to prior to bottling, the properties of the bottles as packaging, and the conditions and length of storage and transport. Additional Fourier-transform infrared spectroscopy (FT-IR) analysis confirmed that about 75% of the particles were polymers, and 50% of them were plastics. Particularly alarming is the fact that the bottled waters mostly contained microplastic particles (MP) of smaller sizes, the kind which is recognized as being the most dangerous to human health. In the study, most particles were in the form of irregular shapes, which may indicate that they come from the destruction of waste or plastic products. This is also indicated by the domination of colourless particles. More particles were found in waters exposed to high and low temperatures than in waters stored at room temperature, potentially indicating that storage conditions for drinking water are important. Taking into account the results obtained, increasing attention should be paid to the health risks posed by such microplastics and there is a clear need to introduce legal regulations on the matter. The lack of any legal guidelines or unified standards in the field of MP research means that the results are not always representative, and it also makes it difficult to compare the results from different studies.

Wydział Geologii, Geofizyki i Ochrony Środowiska
Jakość wody przeznaczonej do spożycia jest niezwykle ważnym aspektem dla wszystkich mieszkańców globu. W celu oceny jej stanu przeprowadzane są badania trzech podstawowych grup wskaźników jakości wody: chemicznych, fizyko-chemicznych i mikrobiologicznych. W analizie chemicznej wody pitnej wykorzystywane są najczęściej metody klasyczne (np. Mohra, Fajansa, Volharda, wersenianowa, Wartha-Pfeifera) oraz instrumentalne (m.in. elektrochemia, spektrofotometria, chromatografia). W projekcie porównano metody badawcze stosowane w Krakowie oraz Berlinie.

Wydział Geologii, Geofizyki i Ochrony Środowiska
Celem pracy jest porównanie efektywności działania filtrów dzbankowych do uzdatniania wody pitnej stosowanych w gospodarstwach domowych. W części teoretycznej omówiono filtrację z zastosowaniem systemów dzbankowych oraz wybrane do pracy wkłady filtrujące. Część praktyczna pracy opierała się na wykonaniu badań laboratoryjnych wody przefiltrowanej przez wytypowane filtry. W pracy dokonano kompleksowego porównania filtrów na podstawie zebranych informacji oraz wyników przeprowadzonych własnych badań laboratoryjnych. Wykonano także ocenę najważniejszych cech decydujących o wyborze danego wkładu. Obecnie filtracja jest efektywną metodą uzdatniania wody i istnieje dużo rodzajów filtrów wykorzystywanych w zależności od potrzeb ich użytkowników. Współcześnie nawet w gospodarstwach domowych użytkownik może efektywnie oczyszczać wodę na wiele różnych sposobów. Jednak najważniejsze jest określenie celu użytkowania filtra, ponieważ mamy różne możliwości wyboru wkładu w zależności od tego, czy woda ma być użytkowana w celach pitnych, czy też stosowana w sprzęcie AGD.

Woda odgrywa ogromną rolę w życiu człowieka. Organizm człowieka wymaga ciągłego nawodnienia w celu zapewnienia prawidłowych procesów fizjologicznych. Wody butelkowane pozwalają nie tylko nawodnić organizm, ale też są cennym źródłem składników mineralnych, które uzupełniają codzienną dietę. W pracy przedstawiono charakterystykę fizykochemiczną wybranych wód butelkowanych dystrybuowanych na terenie miasta Zamość. Opracowano wyniki analiz chemicznych 19 różnych wód oraz dokonano ich klasyfikacji wg rozmaitych kryteriów (mineralizacji, pH, typu wody). W wyniku tych opracowań ustalono, że w mieście Zamość dominują średniozmineralizowane wody o odczynie słabo zasadowym. Najczęściej spotykanym typem wody są wody wodorowęglanowo-wapniowo-magnezowe.
