“…While these observations should raise significant questions about chemical hygiene and fugitive emissions at the plants, this was a time when scientists often carried out experiments on themselves or people they knew and some level of exposure to chemicals was tolerated. 5, 6 When combined with prior discoveries, 7 these observations from industry helped propel the case for chlorine-based disinfection and led to widespread implementation of water chlorination processes with significant reductions in mortality rates. 8,9 Additional rapid research and technological discoveries led to new preparation methods for NaOCl, 10 and the commercial production of chlorine containing solutions as disinfectants.…”
