Chemical information study of wastewater
(review)

Summary

The research discipline «Chemical information study of wastewater» has originated and made rapid strides since the beginning of 2000-ies in response to the demand of developing the channels of acquiring the information on the use of broad spectrum of banned narcotics and pharmaceuticals, on the effect of toxic substances, on some health indicators of the population and its size inside the territory under the study. Compared to the traditional methods of questioning and social-epidemiologic studies that imply the compilation of statistics, study of medical reports, acquisition of the information on the production and sale of the relevant medications the considered approach has certain advantages and provides for establishing continuous monitoring almost on a real-time basis. The method includes measuring the concentrations of active substances and/or metabolites of the medications studied that enter the sewer as a result of the excretion from the human organism and using the method of this data processing to determine the level of consumption of medications or narcotics by the population living on the territory served by the sewer network. Similarly the level of the population exposure to the impact of pollutants can be determined. The data obtained in some countries with the use of the considered approach corresponds to the results of the traditional studies, and, in some cases is a successful supplement. It is supposed that the significance and efficiency of the method will grow as well as under the conditions of the sewer network upgrade.
