A new study by researchers at the Bengaluru-based Indian Institute of Science (IISc) has found microplastics in fish, causing growth defects, including skeletal deformities, in River Cauvery in south India. The study was conducted at the Krishnaraja Sagar dam, located below the confluence of river Cauvery with its tributaries Hemavati and Lakshmana Tirtha, in the Mandya district of Karnataka. The researchers collected water samples from three different locations with varying water flow speeds – fast-flowing, slow-flowing and stagnant – since water speed is known to affect the concentration of pollutants.
