Air pollution represents at present the biggest threat to human health due to high levels of pollutant emissions, usually in high-traffic urban areas. Air pollution has been associated with a number of health problems, including heart disease and lung cancer. Urbanization associated with rapid industrial development has led to serious air pollution problems in many large cities across Europe with significant impact on public health and even on the global climate. Information on air quality in urban areas is an imp...

In this paper, we consider such dangerous disasters as wildfires. Wildfires are global sources of gas and aerosol emissions into the atmosphere and considered as one of the main factors of environmental risk, causing disbalance of the climate system of the Northern Eurasia and the planet as a whole. Taking into account terrain features and characteristic spatial scale of the Northern Eurasia, we suggest to use a satellite monitoring system for urgent detection of fire origins and assessment of volumes of hazardous...

Climate change mitigation is a relevant topic in now days. One of the main sources of greenhouse gases (GHG) and air pollutants (including ammonia) emissions that promoting climate change is agriculture sector. Considerable part of GHG and ammonia emissions from agriculture in Baltic region is forming in dairy farms. The aim of the research is to estimate differences between conventional and organic dairy farms in context of GHG and ammonia emissions, taking into account livestock feeding and manure management pra...

Due to more and more restrictive environment requirements in the field of pollutant emissions of co-generative plants are imposing researches related to the more efficient work of those related to duct burners. Within in a co-generative group, placing the post combustion setup before the turbo engine makes that engine's performances to be influenced related to: flame stability, efficiency and emissions. The paper presents the results of a duct burner achieved on a test bench, when it operates at partial loads on n...

Air pollution is a big problem of the last few decades due to aggression on human health, on all environmental components, generally on the natural or built environment.European directives on environment quality introduce the concept of modeling on quality of air ambient assessment and management, as a technique of measurement, calculation, prediction and assessment of the levels of pollutants.It is very important the role that the modeling pollutant dispersion has in the air quality assessment, while representing...

The aim of the research is to determine emitted greenhouse gases (GHG) and ammonia emission distinction between two fertilizers types: ammonia nitrate and carbamide (urea). One of the most fertile soils in Latvia are located in Zemgale Region and it is used in research. Samples of tilled soil are used for the research according to the conditions of soil. One of influential factors of the GHG emissions is soil moisture, because humidity in combination with temperature controls the activity of microorganisms and oth...
