Phosphorus resources and fractions in peat-muck soils
Page range: 1 - 6
The goal of the research was to determine the resources and speciation (forms of occurrence) of phosphorus in organic soils of drained fens of the Wysoczyzna Siedlecka. Two profiles of muck soils were generated from different peats. Basic physical and chemical properties of the soils and the quantity, resources and fractions of phosphorus in the soil were determined.
The majority of the total resource of soil phosphorus was accumulated in the muck horizons of the analysed soils. The total content of phosphorus materially correlated with characteristically variable parameters in the moorshification process (voids free bulk density of the content of organic matter, C/N ratio and C/P ratio). Additionally, a material positive correlation of the content of phosphorus with the content of iron, manganese and aluminium was observed.
The moorshification process of the analysed soils entails the qualitative transformation of phosphorus compounds, mainly involving an increase in the share of more labile and easily available forms, forms released in reduction conditions and forms combined with metallic oxides, apatite, carbonate and labile organic forms.

Data mining methods of healthy indoor climate coefficients for comfortable well-being
Page range: 7 - 12
This article provides information about a currently developed measurement and analysis system ‘Smart Monitoring’, which is used on scientific project in terms of healthy indoor air coefficients, as well as the processing of the collected data for machine learning algorithms. The target is to reduce CO2 emissions caused by wrong ventilation habits in building sector after renovation process in older buildings.

Share of road transport in greenhouse gas emissions in Poland in 1988–2015
Page range: 13 - 20
The results of an analysis of the greenhouse gas (GHG) emission inventory in Poland in the years 1988–2015 are presented, paying special attention to the impact of road transport on the intensification of greenhouse effect. The analysis was made based on the official results compiled by the National Centre for Emissions Management and Balancing (KOBiZE) at the Institute of Environmental Protection – National Research Institute.
It was found that carbon dioxide emission represented the dominant part of the total GHG emissions, despite that there were other gases having far greater greenhouse effect potential. There was a general downward trend for the national annual emission of basic GHGs. The estimated share of road transport in the GHGs emission was not high: from 4% in 1988 to around 12% in 2015.
For motor vehicles, there is a dominant share in the GHGs emissions of passenger cars: (50 ÷ 60)%.
In the years 1988–2015, there was a relative decrease by about 32% in the national annual emission of carbon dioxide equivalent from all sources covered by the inventory. That notwithstanding, the national annual emission of carbon dioxide equivalent arising from transportation increased generally by about 93% and that from the road transport increased by as much as 117%. The increase in GHGs emissions from motor vehicles resulted mainly from a significant growth in car numbers. Technical progress in the construction of motor vehicles can be evaluated by considering the average annual emission of carbon dioxide equivalent from a conventional car, which has been decreasing since 1998.
