Influence of meteorological factors on the secondary contamination of atmospheric air by formaldehyde ( on example of city of Kyiv).
Many authors on the basis of researches give information that a motor transport is the basic source of contamination of atmospheric air of cities of Ukraine. This work touches the estimation of level and dynamics of contamination of m. Kyiv extrass from a motor transport and influence of meteorological factors of locality on the degree of atmospheric contamination (including secondary one as a result of actinic transformations). Authors set connection between the components of SO, Nox, CHOH and ambient temperature, on the basis of analysis of the last five years of statistical information of basic components contaminations from a motor transport, which take part in formation of actinic transformations. Authors found out close cross-correlation connection between the molecules of Nox, CHOH and average monthly values of temperature on the basis of analysis of these monitoring supervisions. Also there were investigational processes of formation of molecules of SNON depending on other climatic factors of city of Kyiv, namely: to humidity of air, speed of wind and index of acidity of atmosphere (pH). It is well-proven that formation of formaldehyde in mid air above motor transport ways the degree of acidificationof atmospheric fallouts influences mediated. However have direct cross-correlation connection of relative humidity of air and speed of wind. Temperature terms play a key role in forming of the secondary contamination formaldehyde above motor transport overpasses and he takes into account other climatic factors of locality mediated. Speed of reaction of transformation of hydrocarbons in formaldehyde at neutral meteorological terms is considered on the example of motor-car upshot of the Darnicka square. The decision of equalization of speed of transformation of extrass of hydrocarbons is found in formaldehyde by the decision of equalization of Arreniusa. This method can be applied for other cities of Ukraine. The conducted researches will allow to promote ecological strength security on the urbanized territories by the improvement of questions of acceptance of administrative decisions at building and reconstruction of motor-car overpasses of city, and also at forming of strategic plans of ecological development of city and setting of nature protection measures.
