Abstract/Description: | Fish mortality on a large scale occurred in the Chaliyar river near Calicut from 7-3-1979 to 16-3-1979 in the region between Elamaram and Pallikkadavu. Information gathered from the inhabitants on the banks of the river revealed that large quantities of wastewater from the Gwalior Rayons Factory located at Mavoor was seen discharged into the river through the emergency outlet at Elamaram, on the evening of 6-3-1979. Apart from the low pH causing the mortality, the disappearance of these fishes from the heavily polluted areas and the dislocation of the Nereid worms from their habitat would also reveal the possibility of occurrence of some metallic poison in the water. The Biological Oxygen Demand of the effluent determined on several occasions earlier showed no ill effect to the biological organisms in the water. Government of Kerala has now decided to close down the Pulp and Fibre divisions of the Factory till pollution abatement measures are completed. |
