Abstract
Water extract of respirable particulate matter (RPM) was analyzed by Ion chromatography technique to investigate the
presence of nitrite (NO2) as secondary aerosol in ambient environment. The nitrite particulates undergo photo hydroxyl radical
reaction in environment produce nitrous acid, which reacts with metal and absorbs on RPM as water-soluble metal salt. The
mean concentration of nitrite was 20.86 .g m-3 in ambient environment. Regression analysis showed that the relationship for
respirable particulate matter and nitrite (RPM-NO2, R2=0.742) was positively significant. We are reporting the presence of nitrite
as an aerosol in ambient environment.
