On the other hand, consuming fishes killed with thiodan can have severe impacts on humans as well. Thiodan is one of the Persistent Organic Pollutants (POPs). The molecules of POPs remain in human fat and have severe long-term health as well as genetic impacts on humans.... Read Full Article Akanshya Shah
