Caspian Sea, Leading Threats in terms of Pollution and Hydrological Crises
Journal Title: International Journal of Farming and Allied Sciences - Year 2017, Vol 6, Issue 4
Abstract
Caspian Sea, largest enclosed inland body of water in the world, has been constantly affected by different pollution sources due to its special ecological properties, geographic limitations and different onshore/offshore human activities. The most important pollution source of Caspian Sea is daily extraction and transportation of crude oil and gas. In addition to different natural and man-caused contaminations threating this water body, numerous hydrological threats are influencing this strategic sea. Depth change of this lake is one these threats. In last century the lake has experienced three periods of rapid decrease, slow decrease and slow increase in depth while recent observation shows the reduction of water depth again. These water depth changes had several effects on this enclosed sea that caused pollution enhancement in many ways. The purpose of this paper is to provide a clear description of quality and severity of threats against this valuable lake that could be an important step in identifying threats and potential opportunities in this field.
