The Centre for Science and Environment's Pollution Monitoring Laboratory tested 57 soft drink samples of 11 soft drinks brands. Journalists and researchers travelling for stories collected samples from different states and cities of India -- bought bottles from Burnihat in Meghalaya, Bharuch in Gujarat, Palakkad in Kerala to Jalandhar in Punjab. Unlike the 2003 pesticide in soft drink study, when 36 samples from Delhi were procured, these samples are from 25 different soft drink manufacturing plants spread over 12 states
