The article examines the problems of determining damage caused by illegal acts of economic activity to water bodies of hydroelectric power plants as landscape objects. It proposes calculating the damage to a river, lake, or pond depending on the value of the water body, which is determined by the...

Naphthalene is polycyclic aromatic hydrocarbon (PAH) containing only carbon and hydrogen that are composed of multiple aromatic rings. The simplest PAH, naphthalene, consists of two condensed benzene rings and shows the highest solubility in water. Due to this naphthalene could have a negative...

This article discusses various corn tillage technologies and analyses their energy consumption and GHG emissions. The experimental research and analytical calculations took place in Lithuania and were carried out using five different tillage technologies of varying intensities: deep ploughing,...

This paper deals with the problem of pollution emission into environment. There are reviewed theoretical and experimental research works performed by foreign authors. Approach to the new European driving cycle (NEDC) observing at the existing laboratory conditions the volume of pollutants emitted...

In 2003, an experimental wastewater treatment facilities of the milk collection post were arranged in Padargupiai village, in Artiogala (Raseiniai district). As the pollution of such kind of wastewater after primary treatment is twice higher than that of domestic wastewater, the filtration path in...

To improve the phosphorus sorption processes, the locally excavated material - dolomite - was chosen as the media of the filter. The object of the research was a vertical constructed wetland with the dolomite used as the filter media. Firstly, comparative-data retrieval experiments were conducted...

There have been many discussions in Lithuania about a strategy for reducing the impact of climate change. Members of the international community agree that reducing greenhouse gas emissions to the atmosphere is necessary to avoid dangerous climate change. The main greenhouse gas emissions from...

The increasing amount of vehicles as well as the amount of exhaust pollutant stimulates governments to stiffen the requirements of gas-engine emission. One of the most noxious compounds in exhaust is nitric oxides (NO_x), when they got into atmosphere during chemical reactions they make acid...

The article analyses the influence of pollution and climatic factors on 45-year-old Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) H. Karst.) and Siberian larch (Larix sibirica Ladeb.) stands growing near nitrogen fertilizer plant "Achema". The analysis of the radial increment ...

The objective of this study was to determine the sources and intensity of cow farms air pollution from different air pollution sources. The main gas emission sources in cow farms were estimated, samples were taken and under laboratory conditions gas emission intensity was determined. The highest CO...
