Use of benthic foraminifera as a proxy for monitoring heavy metal pollution in the Swarnamukhi estuary, southeast coast of India

Benthic foraminiferal assemblages were surveyed as potential indicators of heavy metal pollution of sediments from Swarnamukhi estuary, southeast India. Grain size analysis indicated that the sediments were deposited under low energy conditions. Results of assessment by factor analysis and hierarchi...
