Environment tobacco smoke (ETS) is an important source of anthropogenic pollution in indoor environment. This paper reports an environmental chamber study of pollutants released from ETS generated by smoking cigarettes in the chamber. Six cigarettes samples sold in Hong Kong and the Mainland of China were characterized. Gaseous pollutants: carbon monoxide (CO), sulphur dioxide (SO 2 ), nitric oxide (NO), nitrogen dioxide (NO 2 ), methane (CH 4 ), non-methane hydrocarbon (NMHC), carbonyls and

Acetaldehyde, acetone and formaldehyde were the three most abundant carbonyls. A total of 18 aromatic and chlorinated VOCs were quantified. Among them, benzene and toluene were the two most abundant VOCs. OC was more dominant (> 93% of TC) than EC. The amounts of tar and nicotine in the cigarettes could have a direct correlation to the PM emitted. Menthol, an additive in cigarettes could also contribute to the ETS pollutants. The indoor ETS could be removed by a higher air exchange rate that would also minimise secondary VOCs formation.
