- Abstract:
- ... Wetlands are highly sensitive to pollution effects as they are usually low lands in comparison to the surroundings. Consequently, pollution with heavy metals in the wetlands ecosystems may have changed the ecosystem's biogeochemistry. Gomishan and Zarivar wetlands are regarded as two of the most important wetland regions in south eastern corner of Caspian Sea and in Western Iran respectively. We r ...
