Dmytrykov V. Ecological monitoring of microimpurity of polycyclic compounds in air environment in absence of the standards.

In the dissertation at a practical level the decisions of the important social problem - increase of opportunities of system of ecological monitoring of polycyclic connections showing toxical properties, in air environment are offered. The problem is solved by an establishment of laws and construction of the models making a basis of offered techniques and the recommendations, for expansion of opportunities of expert systems of ecological monitoring. The perfection of system of the eco-analytical control - main component of ecological monitoring of polycyclic connections - assumes development high-sensitivity chromatographic methods and computer- chromatographic systems. The essence of the decision consists in sharing the designed characteristics of indexes of linkage, indexes of keeping, physic-chemical characteristics for revealing polycyclic connections in air in absence of the standards by methods highly effective gas-liquid chromatography of the high performance liquid chromatography. The structurepolycyclic hydrocarbons, contained in air environment of a metallurgical complex, is given. With the purpose of increase of a level of reliability of results of definitions of microimpurity pollutants the systems of suppression of handicaps of a signal of the detector are developed. The application of filters for primary processing of a signal has permitted to establish a rational number of automatically chosen ranges of measurement of a signal of the detector. The correction amplitude-frequency the characteristics filtering of a signal of the detector is offered. The principles of the qualitative and quantitative analysis pollutants of air in absence of the standards are applied for revealing microimpurity of polycyclic connections in air of a metallurgical plants, at research components of structure of chemical products of thermal processing coal - potential technical pollutants. With the aid of computer-chromatographic system is developed and the "Technique of fluorescent definition of benz[a]pyrene is introduced in air environment". The technique has universal character and can be used for the eco-analytical control others persistent organic pollutants in natural environments. The expert system of ecological monitoring of air environment of module type is offered.
