Summary
The levels of personal exposures to nitrogen dioxide, and NO2 concentrations indoors and outdoors were compared among the USA, Japan, Korea, Taiwan, Thailand, and the Philippines. The measurements were carried out mainly in winter and in some cases in summer. The personal exposures as well as environmental NO2 concentrations were higher and their variations were wider in winter than in summer in northern countries where space heating was required. The distribution pattern of the personal exposures in winter in southern countries were similar to that found in the summer in northern countries. NO2 emission from space heaters and air exchange rates were found to be determinant factors of indoor concentrations. The personal exposures ranged between outdoor and indoor NO2 concentrations. The unvented space heater, particularly unvented kerosine heater elevated indoor NO2 concentrations and, in consequence, personal exposures.
