Air quality in the Agglomeration of Krakow is determined by many factors, which include, among others, unfavorable location and the resulting meteorological conditions unfavorable for self-cleaning of ambient air. The paper presents a few examples illustrating the impact of selected meteorological factors on some pollutant concentrations in the air in Krakow. Among these, special attention was paid to the ambient air temperature (indirectly influencing the level of air emissions from the municipal sector in the winter season) as well as the wind speed and the mixing layer height. On the basis performed analyzes were to draw conclusions on meteorological restrictions …

The study assessed the chemical and heavy metals content in surface water samples collected at 9 points from 3 different streams within a radius of 5 kilometers to the factory, and an additional control water sample collected from a stream at Tarhembe, 12 kilometers from the factory. Laboratory analyses were conducted for 18 parameters, while mean, maximum and minimum values, and standard deviation for all parameters tested were derived using SPSS Version 15. Using the WHO (2011) Guidelines for Drinking Water, the concentration levels of pollutants in water samples were determined for all 18 parameters to establish whether or not …

Landfills are the primary option for waste disposal all over the world. Most of the landfill sites across the world are old and are not engineered to prevent contamination of the underlying soil and groundwater by the toxic leachate. The pollutants from landfill leachate have accumulative and detrimental effect on the ecology and food chains leading to carcinogenic effects, acute toxicity and genotoxicity among human beings. Management of this highly toxic leachate presents a challenging problem to the regulatory authorities who have set specific regulations regarding maximum limits of contaminants in treated leachate prior to disposal into the environment to …
