The objective of the present study was to evaluate by means of chemical analyses the quality of water collected from fish pond Tataru, Calarasi County. The water samples were collected during May 2017 from five sampling points (A, B, C, D, E) from three depths (surface layer, half of maximum depth, maximum depth). The subjected parameters were pH, electrical conductivity (EC), total hardness (TH), chemical oxygen demand (COD), nitrate nitrogen N-NO3-, nitrite nitrogen N-NO2-, ammonium nitrogen N-NH4+, phosphate ph...

The aim of the present study was to investigate the level of pollution of water collected from Snagov Lake. The water samples were collected during May 2017 from five sampling points (A, B, C, D, E) from three depths (surface layer, half of maximum depth, maximum depth). The subjected parameters were pH, electrical conductivity (EC), total hardness (TH), chemical oxygen demand (COD), nitrate nitrogen N-NO3-, nitrite nitrogen N-NO2-, ammonium nitrogen N-NH4+, phosphate phosphorus P-PO43- and some metals (Al, As, Ba...

Safe water quality is strongly related with good human health and the presence of undesirable species may pose various disturbances. Accordingly, evaluation of drinking water quality is needed in order to secure if water is appropriate for human consumption. The aim of the research was to evaluate the quality of drinking water collected from M?neciu-Ungureni, Prahova County during 6 sampling campaigns from 7 wells. The evaluation was based on determination of some specific parameters, as follows: pH, electrical co...

Maize (Zea mays L.) is the most important cereal after wheat and rice grown widely throughout the world, playing a major role in human diet or as livestock fodder. Water and nitrogen are the most limiting factors for maize grain yield and it is important to evaluate the response of maize crop to irrigation associated to N fertilization in order to obtain high yields and to prevent nitrate pollution. In this context, it was designed an experiment with the main purpose to analyze the variability of yield potential a...
