RESUMEN
The main goal of this study is to compare the concentrations of anionic synthetic surfactants (ASS) in drinking and surface waters in Armenia and to explore possible relationship with diseases of the skin and digestive system. Surfactants are widely employed in numerous field of the economy, are in contact with the entire population throughout life and can be harmful to human health.The samples of drinking and surface waters (n = 144) were collected in Kotayk province to analyze ASS concentrations, physicochemical parameters and phytotoxic activity. The prevalence of diseases was analyzed for different population groups. ASS concentrations in surface waters were significantly higher in summer compared to spring (p = 0.006). In drinking water, concentrations were also higher in summer, but not significantly. In surface waters, ASS levels were 2.4-3 times higher compared to drinking (p = 0.03) and exceeded the permissible limit by 1.4-2.9 times in summer and fall. No phytotoxic activity and differences in both classes of diseases and age groups were revealed. The determination of ASS in both surface and drinking waters with the same trend showed their interrelation to a certain extent. This study provides important information for future research and action which will contribute to the sustainable development of local communities.
