Why is it important?
The available data can be used as a baseline to track the effectiveness of policies for the conservation of the Ashtamudi wetland.
Perspectives
Monitoring heavy metals (HM) and persistent organic pollutants (POP) has become more important recently, as they pose serious threats to tropical aquatic ecosystems. Ashtamudi wetland must be protected and monitored due to the intense urbanisation and other anthropogenic activities that occur in the nearby areas of this wetland. This study aims to identify potential sources of POPs (OCPs, PCBs, and PAHs) and heavy metals in surface sediments collected from Ashtamudi wetland, as well as to assess their ecological risk
