Background: Water quality for tourists visiting South Luangwa National Park and other less developed regions is of the utmost importance in order to avoid gastrointestinal infections; one of the most common diseases among tourists. It is also important to the health of the local tourist accommodations and the local tourist economy. Methods: Water quality samples assessing microbiological contamination were taken from the borehole and point of use in 14 tourist lodges and camps. Turbidity was assessed optically with a DelAlgua turbidity tube. For microbiological analysis, samples were incubated in the DelAgua Dual Incubator at 37°C and 44°C. Thermotolerant Escherichia coli (E. coli) was used as theindicator bacterium for fecal pollution. Water samples were classified based of risk levels for pollution determined by the World Health Organization (WHO). Results: Fifty percent of borehole samples showed no contamination. Two were found to be at high risk and the others ranged between low and intermediate risk. At the point of use, 80% of the samples were clean and compliant with WHO guidelines. Water contamination generally improved from the borehole to point of use. Turbidity at borehole samples were clear in 75% of possible samples. At the point of use, turbidity was clear in 81% of samples. Conclusion: This study establishes the first baseline water quality data for tourist facilities at South Luangwa National Park in Zambia. While water quality at most sites is clean for human use, a regular monitoring system accompanied by maintenance is recommended.

W Polsce metoda oceny stanu ekologicznego jezior na podstawie makrofitów opracowana została na potrzeby rutynowego monitoringu wód w latach 2005–2006 na zlecenie ówczesnego Ministra Środowiska. Do procesu tego posłużyło 156 jezior. Zbiorniki zostały pogrupowane pod względem różnorodności roślinności oraz parametrów abiotycznych. Wśród nich wyodrębniono cztery grupy jezior makrofitowych: I – jeziora o wodach miękkich (lobeliowe), II – jeziora o wodach bogatych w wapń (ramienicowe głębokie), III – jeziora o wodach bogatych w wapń (ramienicowe płytkie), a także IV – jeziora łęczyńsko-włodawskie. Dla drugiego oraz trzeciego typu, odpowiednio jezior stratyfikowanych i niestratyfikowanych zaproponowano odrębną klasyfikację ocenianą za pomocą Makrofitowego Indeksu Stanu Ekologicznego. Podstawą jego opracowania była metoda makrofitoindykacji roślinności jezior rejonu Laski w Borach Tucholskich zaproponowana przez profesora Mariana Rejewskiego w latach 70. XX w, a udoskonalona w następnych latach przez profesor Hannę Ciecierską. Określała ona bioróżnorodność na poziomie zbiorowisk roślinnych fitolitoralu tworzonych przez makrofity. Metoda ESMI obejmuje zarówno badania roślinności przeprowadzone w terenie z etapem przygotowawczym oraz część polegającą na wyliczaniu samych wskaźników makrofitowych. Indeks przyjmuje wartości od 0, obrazującego zły stan ekologiczny, do 1 odzwierciedlającego stan bardzo dobry. W trakcie wyliczania końcowego indeksu ESMI uwzględnia się parametry takie jak: różnorodność fitocenotyczna, maksymalna różnorodność fitocenotyczna, indeks kolonizacyjny, powierzchnia fitolitoralu obliczona jako suma powierzchni wszystkich zespołów roślinnych oraz powierzchnia samego jeziora. Zarówno poszczególne wskaźniki wchodzące w skład ESMI uwzględniające skład taksonomiczny oraz obfitość makrofitów, jak i sam zespolony indeks, wyraźnie i w sposób kierunkowy reagują na antropopresję. Jako jej główny, ale nie jedyny przejaw przyjęto proces eutrofizacji, dlatego otrzymane wyniki klasyfikacji porównywano różnymi wskaźnikami trofii. Zatem, do oceny stanu ekologicznego jezior podlegających presjom innego typu niż przyśpieszona eutrofizacja, metoda ESMI nie powinna być wykorzystywana, ponieważ nie jest ona podatna na te presje. Podobny problem, jak zauważa profesor Hanna Ciecierska dotyczy jezior o niekorzystnym dla rozwoju makrofitów ukształtowaniu dna zbiornika. W związku z tym powinno potraktować się ocenę ESMI jako szacunkową z założeniem, iż może ona ulec zmianie, np. po zawarciu przeliczenia do wzoru ESMI poprawki na ukształtowanie misy jeziornej.

Harmonisation of the laws of the Member States regarding the protection of the environment is one of the tasks of the European Union. Poland joined EU in 2004 and took on various commitments for the improvement of water status. In particular, the Water Framework Directive was a major breakthrough in the assessment of aquatic ecosystems. For the classification of stratified and non-stratified lakes Ecological State Macrophyte Index (ESMI) has been used. In Poland, the method for assessing the ecological status of lakes based on macrophytes has been developed for routine water monitoring shortly after joining the European Union. This index is one of the biological elements in the assessment of ecological status. It considers the whole plant communities in the reservoir. The key factor that ESMI reacts to is anthropopressure, which manifests itself as eutrophication. However, it is crucial that the lakes are also subject to different pressures. In this situation, the ESMI rating becomes only an indicative method. The article describes the role, process of evaluation and the most common problems related to ESMI.

ABSTRACT Human exposure to Emerging Contaminants (ECs) remains a pressing concern, predominantly occurring through diverse vectors such as contaminated soil, water, plants, animals, and microorganisms. This paper investigates the intriguing evolution of water treatment, tracing the transition from ancient rudimentary practices to contemporary sophisticated technologies. Traditional methods, deeply entrenched in centuries of use, encompass biological, physical, and chemical approaches. The article underscores the significance of water treatment in protecting public health and preserving the environment, emphasizing its pivotal role in collective well-being. Water quality standards (WQS) assume a central role in regulating water quality, furnishing a legal framework, and safeguarding human health and ecosystems. Emerging technologies, including Advanced Oxidation Processes, graphene-based filtration, and AI integration, display potential in overcoming limitations associated with traditional methods. Conservation of ecosystems emerges as vital for water quality protection, accentuating the interdependence of ecosystems and water quality. Addressing the drawbacks of traditional methods highlights the necessity for evolving strategies, with ongoing research directed toward optimizing existing methods and exploring emerging technologies to fulfill the demand for clean and safe water.
