The Caspian Sea Transgression (Environmental Medical Aspect)by L. I. Elpiner,
Abstract: From 1978 until 1994 the level of the Caspian Sea has risen by 220 cm, in 1994 by 30 cm. The study of environmental medical situa tion in the Russian zone of the sea transgression impact showed the connection of increased infectious, parasitic, and some other noninfectious diseases with the impact of variable hydrologic situation. The forecasting of further hydrological changes has been elaborated in case no protective measures have been taken from flooding, underf loading, and other water-caused disasters. Environmental medical assessment of the limited use of coastal protective works erected only in places of location of major economic objects and populated areas has been given. Its insignif icant environmental medical efficiency has been disclosed due to direct and indirect negative impact of water factor in semi-island and island settings and due to further deterioration of sanitary-epidemiologic situation and socio-economic conditions forecasted. As it is economically non-beneficial to use a dense extensive coastal protective system, a complex of preventive measures is proposed to improve present environmental medical status and to avert deterioration of the coastal area (limited coastal protection including) under new hydrological conditions. The results of the study testify to the importance of environmental medical forecasting when making projects of coastal protective works in zones with increased sea level impact.
