- Industrial activity, particularly coal fly ash pollution emanating from ash conveyance, storage and impounding structures have drastically altered the hydrology, ecology and topography of the Ennore creek says an expert study commissioned by the National Green Tribunal.
- The expert committee reviewed the environmental impacts of coal ash pollution on Ennore creek and areas surrounding North Chennai Thermal Power Station (NCTPS) at Ennore
- A total of 20 samples of fish, including fin fish, crab, prawn and oyster/mussels were taken. All samples contained detectable levels of copper which could cause deformity of gills and harm their ability to navigate and hunt for food.
- The levels of cadmium and lead found in the fish taken from the creek were in excess of maximum concentration limits prescribed by European Union regulations.
- Five samples of home-grown vegetables also had detectable and significant levels of chromium and lead.
