Abstract |
The attention of many researchers has been attracted to the method of adsorbing small amounts of organic contaminants in activated charcoal with their subsequent extraction with chloroform (CCE). After selection of the brand of charcoal and testing the method under laboratory conditions, in 1967-1970 field studies were conducted on the Kama River in 7 control ranges operated by the city of Perm as well as in Perm tap water. The studies verified the possibility of using the charcoal-chloroform extract method in sanitary practice for comparative evaluation of the levels of contamination in river water by organic components of industrial discharges. Nevertheless, we must note that international standards lack recommendations concerning detailed quantitative and qualitative testing of individual organic materials in this complex. This is demanded by the principles and methodological basis of Soviet water law which, founded on hygienic standardization, requires not only the quantitative characteristics of the total content of contaminants, but also quantitative and qualitative evaluation of individual components in this complex. |
