Chemistry and environment has executed Maksimov Alexander
The most serious problems of our time connected with ecology: -Concourse of the Rubbish -Acid Rain - Hotbed Effect -Ozone Holes -Climatic Catastrophes
Chemical contamination biosphers: -Oxides of carbon -Sulphurous angigrid -Hydrogen sulfide and seroyglerod -oxideses of the nitrogen of the joining -the fluorine of the joining
contamination of ground: -pesticides -tart ripostes on land
Problem of the soiling the world ocean pesticideses syntetic surrface material join with kantserogennymy characteristic heavy metals unset departure for the reason dumping
One more problem of modern biosphere - a photochemical fog (smog). The photochemical fog represents a multicomponent mix of gases and aerosol particles of a primary and secondary origin. The structure of the basic components of a smog includes ozone, оксиды nitrogen and sulfur, numerous organic connections перекисной the nature, named in aggregate photooxidizers.
Problem of monitoring of emission in atmosphere of polluting substances the industrial enterprises (maximum concentration limit). The priority in the field of working out of maximum permissible concentration in air belongs to the USSR. Maximum concentration limits - such concentration which don't render on the person and its posterity of direct or indirect influence, don't worsen their working capacity, state of health, and also sanitaryconditions of life of people.
The modern person can't do without chemistry. But thus it is necessary to protect world around somehow. Wildlife management our century problem, the problem which has become social.
