  1. ATMOSPHERIC FALLS (DRY, WET) – INDICATOROF CLIMATIC-CHEMICAL INTERACTION ASSESSMENT Hydrometeorological Research InstituteUZHYDROMETDr. Galina A. TOLKACHEVAYuliya KovalevskayaTatyana SmirnovaE-mail: sanigmi@ albatros.uz

  2. Objectives of the investigation is as following: • assessment of atmosphere composition on the regional level under anthropogenic impact (Aral crisis) • selection of indicators of atmosphere pollution by greenhouse gases • assessment of the role of atmospheric falls (dry, precipitation) as indicators of atmosphere pollution by greenhouse gases, including troposphere aerosols; • data base creation on chemical composition of atmospheric falls (dry, precipitation), anthropogenic emissions into atmosphere, non-standard information on environmental pollution.

  4. CHEMICAL COMPOSITION OF ATMOSPHERE (background, regional) Table2

  5. CHANGES OF ATMOSPHERE POLLUTION INDEX (API ) OVER TASHKENT AND TASHKENT PROVINCE API < 5 - level of air pollution is lawAPI от 5 до 6 – higherAPI > 7 - high and very high

  6. Proportion of water-soluble mineral components in dry atmosphere falls at sampling point

  7. Composition and volume of industrial emissions over Almalyk and TashkentТаблица 4

  8. mg/m3 Standards WHO Standards of Uzbekistan Solid matter dust Concentration of particulate particles in air of cities having more than 100 thousand people in 1996 (according Hydrometservice of Uzbekistan data) Content of PAH sum in atmospheric air of industrial cities of Uzbekistan ng/m3 Tashkent Angren Chirchik Fergana Almalyk Bekabad

  9. Dynamics of flux density changes of sulphates, chlorides, and hydrocarbonates according many years data at the stations of Uzbekistan
