[Harmonization of hygienic standards with the foreign requirements for the quality of drinking water]

The concept of and criteria for harmonization of hygienic standards with the foreign requirements for the quality of drinking water were developed. On their basis, more than 100 sanitary standards for water substances were harmonized with the WHO and EC recommendations and the USA and Canadian standards for drinking water quality. Thirty sanitary standards were corrected and 12 ones were newly established without making experimental studies, among them 18 for carcinogenic substances. The paper provides evidence for the reliability and effectiveness of the Russian sanitary standardization system as to most standardized water substances. It also presents the harmonized standard normal values included into the documents of the water sanitary legislation of Russia.
