ABSTRACT
In the article the results of nitrogen compounds (NH4, NO2-, NO3-) in water samples collected at six locations (sampling points) at the Oliwa Stream will be presented. The study was carried out in 2016-2017, analyzing the changes caused by rainfall in the urban catchment. After the spring rain the concentration of ammonia nitrogen is considerably higher than in autumn. The results were compared with the Regulation of the Minister of the Environment, which describes two main classes of water purity.
