Celem opracowania było określenie przestrzennego i sezonowego zróżnicowania wybranych cech jakości wody w zlewni zurbanizowanej. Pomiary terenowe przeprowadzono w silnie przekształconej zlewni Potoku Służewieckiego, będącego największym dopływem Wisły płynącym w granicach Warszawy. Od listopada 2017 do października 2018 r. w regularnym cyklu dwutygodniowym łącznie w 11 punktach pomiarowych oznaczono temperaturę wody, nasycenie wody tlenem, przewodnictwo elektryczne oraz odczyn, natomiast w cyklu miesięcznym – stężenie azotanów NO3 i fosforanów PO4 . Wyniki wskazały, że główną przyczyną przestrzennego zróżnicowania reżimu fizyczno-chemicznego Potoku Służewieckiego są przepływowe zbiorniki wodne, powodujące przekształcenie warunków termiczno-tlenowych oraz unieruchomienie jonów. Wyraźny wpływ na jakość wód Potoku Służewieckiego miały także jego dopływy oraz funkcjonowanie lotniskowej oczyszczalni wód opadowych. Stwierdzono wyraźne sezonowe zróżnicowanie cech fizyczno-chemicznych, uzależnione od warunków meteorologicznych i hydrologicznych, cyklu wegetacyjnego organizmów fotosyntetyzujących oraz zmian antropopresji.

A study was conducted to evaluate the water quality parameters of pond water at Mymensingh Urban region. The water samples were collected from 30 ponds located at Mymensingh Urban Region during August to October 2010. The chemical analyses of water samples included pH, EC, Na, K, Ca, S, Mn and As were done by standard methods. The chemical properties in pond water were found pH 6.68 to 7.14, EC 227 to 700 ?Scm-1, Na 15.57 to 36.00 ppm, K 3.83 to 16.16 ppm, Ca 2.01 to 7.29 ppm, S 1.61 to 4.67 ppm, Mn 0.33 to 0.684 ppm and As 0.0011 to 0.0059 ppm. The pH values of water samples revealed that water samples were acidic to slightly alkaline in nature. The EC value revealed that water samples were medium salinity except one sample and also good for irrigation. According to drinking water standard Mn toxicity was detected in pond water. Considering Na, Ca and S ions pond water was safe for irrigation and aquaculture. In case of K ion, all the samples were suitable for irrigation but unsuitable for aquaculture.J. Environ.

Monitoring of environmental factors allows the achievement of some important objectives regarding water quality, forecasting, warning and intervention. The aim of this paper is to investigate water quality parameters in some potential pollutant sources from northern, southern and east-southern areas of Romania. Surface water quality data for some selected chemical parameters were collected and analyzed at different points from March to May 2017.

This study was conducted in order to understand the taste and odour problems that occurred in the Seine and the Marne rivers during the severe drought of 1976. Samples were taken every 15 days from several locations in the rivers themselves and from storage reservoirs upstream from Paris. Algae and actinomycetes were identified and counted. Metabolite concentrations were measured. These data were correlated with threshold odor numbers and bacteriological water quality parameters.
