Elevated levels of chloramines and chlorine detected near an indoor sports complex Open
Chlorinated cleaning products containing hypochlorous acid (HOCl) and hypochlorite ion (OCl − ) act as sources of toxic chloramines (NH 2 Cl, NHCl 2 , NCl 3 ) and atmospheric oxidant precursors ( i.e. Cl 2 ) which impact air quality.
