“…Various local sources with different polluting potential have impact upon ambient air quality in built-up areas. Besides main air pollutants attention is paid to increased concentrations of other gases like 3 , CH 4 , N 2 O, CFCs etc., in regards with their influence on global climate system change and new methods for their measurement are developed [1,13]. Recently the level of PM 10 in many urban territories in Bulgaria is high above the limit values.…”

This dispersion model and assessment of air pollution with particulate matter (PM10) in the town of Svishtov, Bulgaria are developed in accordance with the requirements of Bulgarian legislation and the Framework Directive 96/62/EC on the assessment and control of the Atmospheric Air Quality. Based on an assessment of sources of air pollution in the town of Svishtov, Bulgaria are classified input data for the model including point, area and line sources of PM10. Quantitative results of modeling of the main sources of PM10 and background air pollution of Svishtov for 2007- 2010 confirm that local ambient pollution and emissions of PM10 from residential heating is a key contributor to atmospheric pollution in the city.

“…The aim is to make correlations for the choice of the optical components of spectrophotometer when the light intensity, range of scanning, resolution and condition for compact construction are known [2,3,4]. The concrete aim is to situate the optical components and to define the correlation of their parameters.…”

The work is about the design and development of compact optical system for spectrophotometer. The equation of plain diffraction grating allows the design of a compact appliance with optimal combination of the separate optical elements and their parameters. There are certain constructions of spectral appliances, which are developed by leading companies. The path of the rays is used, it is reflected by mirrors many times and the result is a compact construction. There are company catalogues for the choice of separate optical elements when developing appliances, but they do not describe the elements in detail. These facts do not allow scientific research and experimental construction on a high scientific and technical level with own recourses and materials.
