Toxic mercury haunts TN long after thermometer unit was shut
A new study has found high levels of toxic mercury in vegetation and sediment collected from the vicinity of a thermometer factory which was shut 14 years ago in the hill station of Kodaikanal in Tamil Nadu, an NGO claimed today.
“Lichen samples contained 53 mg/kg of mercury, a moss sample had 8.68 mg/kg,” Advisor, Community Environmental Monitoring, Nityanand Jayaraman said here.
The NGO had the samples analysed at the Department of Atomic Energy’s National Centre for Compositional Characterisation of Materials in Hyderabad, he said.
