BLACK CARBON CONTENT AND DISTRIBUTION IN SURFACE SEDIMENTS FROM TEMPERATE-ZONE RESERVOIRS (POLAND)

This paper presents the results of first studies concerning the content of black carbon (BC) (which may be played a significant role in the accumulation of dangerous pollutants) in sediments of three reservoirs located in south-eastern Poland. The BC studies made use of the chemical-thermal oxidation method (CTO-375).

Metrological support of measurement of organic carbon content in mineral waters

The studying and standardization of the mineral waters requires mandatory content control of their chemical indexes. Nearby with the dissolve salts there are always exist the organic substances. The mineral waters with high organic substances (Corg, total organic carbon no less than 5,0 mg/l) are used for treating the hepatobiliary system deceases, urinary tracts deceases, and genital and metabolism disturbances. The researches of safety and quality of the mineral waters relate to the area of the state`s metrological control and supervision.
