Anthropogenic heavy metal pollution in surface waters – Field trip to Tamil Nadu, South India

Tank Chidambaram (Groß).pngDr. Linda Taft (Department of Geographie, University of Bonn) and her colleague PD Dr. Sven Sindern (Institute of Mineralogy and Economic, RWTH Aachen) travelled to the Indian state of Tamil Nadu from Feb 21 to Mar 06, 2020, to conduct fieldwork for their current DFG-Project. The project „Shells of aquatic freshwater gastropods as archives for heavy metal contamination history of a river-coast transition zone“ is a proof-of-concept study in order to assess the suitability of the shells of aquatic gastropods (snails) as environmental pollution archives. Dr. Taft and PD Dr. Sindern sampled gastropod shells from different water bodies such as urban water tanks and brackish to freshwater river zones, where anthropogenic heavy metal input to the environment is assumed. In further work steps they will investigate the systematics of heavy metal incorporation in the shells and then deal with the suitability of the shells as a contamination archive.

The two researchers were able to use the laboratory of Dr. M. Arumugam of Annamalai University in Chidambaram (Centre of Advanced Study in Marine Biology in Parangipettai). PD. Dr. Sven Sindern has signed a MoU with Annamalai University and another one is being prepared by Dr. Linda Taft. The 2-week trip was very successful, not only with regard to the sampling situation, but also with regard to the expansion of Indo-German research cooperation.
