Air pollution has a negative impact on human health and the ecosystem as a whole. It causes a variety of diseases, such as asthma, various lung diseases, cardiovascular diseases, which particularly affect children and the elderly. The aim of the study is to determine how the preparation of melted snow samples for analysis influences concentrations of lead (Pb), zinc (Zn), nickel (Ni), vanadium (V), copper (Cu), manganese (Mn) in snow samples. For snow samples analysis ICP-OES spectrometer "iCAP 7000" is used. In s...

Air pollution in cities caused by traffic is an important environmental and health issue worldwide. Air pollution caused by traffic exceeds air pollution from other anthropogenic sources, such as industrial, various heat supply and residential areas. This study analyzes a wide range of pollutants in snowpacks at different intensity roads in one of the largest cities in Latvia in Jelgava. Snow samples are taken from three sampling points at distance of 1 m, 10 m, and 20 m from the roadway. In the study, various met...

Air pollution is one of the main factors that affects human health. It may affect our health in many ways both long and short term. Exposure time of air pollution increases the risk of respiratory diseases, such as pneumonia, lung cancer, and causes cardiovascular diseases. Air pollution affects different groups of individuals in various ways.

More than half of the world population lives in cities. In 2030, 80% of the world population will live in urban areas, according to United Nations migration forecasts. People who are living in cities are exposed to air pollution. The concentration of air pollution is increased by traffic intensity. Increasing traffic intensity increases the number of automobile congestion in large cities. Therefore, there is a need to implement the measures for reducing air pollution in surroundings. Scientific studies show that e...
