title: Air quality status during Diwali festival of India: a case study.
abstract: The PM(2.5) and PM(10) samples were collected during Diwali celebration from study area and characterized for ionic concentration of four anions (NO(3) (-), NO(2) (-), Cl(-), SO(4) (2-)) and five cations (K(+), Mg(2+), NH(4) (+), Ca(2+), Na(+)). The results showed that the ionic concentrations were three times compared to those on pre and post Diwali days. Predominant ions for PM(2.5) were K(+) 33.7 μg/m(3), Mg(+) 31.6 μg/m(3), SO(4) (2-) 22.1 μg/m(3), NH(4) (+) 17.5 μg/m(3) and NO(3) (-) 18 μg/m(3) and for PM(10) the ionic concentrations were Mg(+) 29.6 μg/m(3), K(+) 26 μg/m(3), SO(4) (2-) 19.9 μg/m(3), NH(4) (+) 16.8 μg/m(3) and NO(3) (-) 16 μg/m(3). While concentration of SO(2) and NO(2) were 17.23, 70.33 μg/m(3) respectively.
