The degree of exposure to carbon monoxide is most often assessed by measuring the blood carboxyhaemoglobin saturation. This measurement is relevant to investigations of acute accidental or deliberate poisoning and of chronic exposure in a domestic or work place environment. Simple spectrophotometric methods based on differential protein precipitation or dithionite reduction are prone to interference from other haemoglobin pigments and are imprecise for low-level estimations. Automated spectrophotometric devices (CO-oximeters) that estimate simultaneously total haemoglobin, percentage oxyhaemoglobin and percentage carboxyhaemoglobin have acceptable accuracy for carboxyhaemoglobin saturation levels of > 5% and are recommended for most clinical purposes. For the investigation of low-level exposure and the detection of increased haemolysis in neonates, more sensitive methods involving the release of carbon monoxide and its measurement by gas chromatography are required. Gas chromatographic methods are also appropriate when examining post-mortem blood samples where putrefaction or heat stress has resulted in a significant change in haemoglobin composition.

The purpose of this article is to highlight and analysis of trends in total emissions of polluting substances in atmospheric air of Mogilev region. The main material. A brief overview of Belarusian scientistsʹ research in the fi eld of geoecological conditions of atmospheric air is given in the article. The article deals with pollutants accumulation in the air of Mogilev region from various sources. Mobile sources (64.1% in 2015) are mainly responsible for air pollution in the region. In 2015 in comparison with 2010 there was a decrease in pollutant emissions as a result of transport functioning. Sources of pollutants accumulating in the air are exhaust gases from internal combustion engines, crankcase gases and fuel evaporation from fuel systems. Automobiles dominate in the structure of vehicles (85.3% in 2015). The article considers dynamics of pollutant emissions from stationary sources. The majority of pollutants are found in the air because of technological processes. Hydrocarbons and sulfur dioxide prevail in the structure of emissions of these sources. Chemical industry enterprises (Mogilev chemical fiber, Mogilev artificial fiber plant, etc.) are the sources of air pollution. Substances of the 4th and 3d danger classes predominate in the structure of pollutants in Mogilev region. Substances of the 1st and 2nd danger classes are insignificant. Conclusions. As a result of the conducted research uneven territorial distribution of emission density of the main pollutants in the air of Mogilev region has been established. Kostiukovich and Krichevsk districts are characterized by high level of emission density of suspended substances, carbon monoxide, sulfur dioxide in the air from stationary sources. Cherikov district is characterized by a low level of carbon monoxide, sulfur dioxide, nitrogen oxide emissions per unit area. 71.4% of the administrative districts of Mogilev region are characterized by an average density level of carbon monoxide emissions from stationary sources in relation to the average regional level, 14.3% of districts by lower level, 4.8% by low level and 9.5% by high level. It is advisable to improve the production technology, to equip enterprises with new gas cleaning facilities in order to reduce the anthropogenic load on the environment.
