SO2, as a pollutant with high reactivity, attracts attention of many scientists due to its property to form acid rains, as well as due to the fact that it is responsible for formation of sulfoxy radicals which can cause serious damage to the environment [1,2]. The acid rain issue, whose pH value is under 5,6, occurs in 40% of the territory in China . European most endangered regions are the Netherlands, Poland, Germany and the Czech Republic . Apart from the primary pollutants such as SO2, NO2, CO2, CO and soot particles, one can also find heavy metal particles in the air which result from various industrial processes (Pb, Cd, As, Ni, Zn and other).
A number of investigations indicate the impact of pollutants on the health of people.…show more content…
Seasons when people are exposed to hazardous effects of pollutants have a considerable effect on health of people . SO2 from the atmosphere impacts increase of blood pressure during the winter, while there is no such effect during the summer . However, the impact of pollutants on blood pressure is not quite clear, which is confirmed by the results of investigation which are contradictory. Pollutants do not have a big influence on the increase of death cases of people over 65. With growing old the impact of pollutants increases . The conncetion between pollutants and death of children younger than 5 is not statisctically important. Investigations show that pollutants do have an impact on the health of people of all age, not only on elderly people .
Weather conditions have a major role in the interaction between pollutants, thus, there is certain difference in the obtained results of investigations conducted at different locations . Pollutants that appear in the air can act separately, however interactions between them can frequently occur and then they have a more negative impact on environment and the living world .
It is hard to specify the diseases which could be caused by SO2, and which could be caused by fine sulphate particles which exist in our surrounding and are created by nucleation of SO2. Sulphate particles with the diameter 2,5 and 10μm have a particularly negative impact .
