Abstract

The paper presents the estimate of externalities caused by methane emission from exploitation of the municipal solid waste landfill in the years 2002-2009. Methane emission was calculated according to the methodology recommended by the IPCC which is briefly presented in the paper. The following parameters were evaluated: mass of the landfilled wastes, correction coefficient for methane based on the landfill characteristics, content of biodegradable carbon based on waste morphology and mass of recovered methane. Based on these parameters, the amount of methane emitted from the landfill during 2002-2009 was estimated at 3.16 Gg.

Abstract

The research was focused on the assessment of the bioaerosol concentration in the air of the Machnacz municipal solid waste landfill and its surrounding. Evaluation of air pollution was made during the autumn season. In the air collected with impactor sampler, the levels of indicator microorganisms - bacteria from the Enterobacteriaceae family, β-haemolytic bacteria, yeasts and yeast-like fungi - were determined. The proposed indicator microorganisms are different from those recommended by Polish Norm PN 89/Z-04111.01. This highlights the specific character of our method. Such selection of indicators allows not only assessing the air pollution of the landfill site but also determining the range of its impact on the surroundings. The results indicate that the landfill is a source of emission and dispersal of bacterial and fungal aerosol, despite its correct management and proper maintenance. The landfill influence on the microbial air quality reaches a distance of 1000-1200 m from the fence. The range of the influence indicates it to be a potential hazard for neighbouring residents.
