Abstract
Studies have documented that passive smoking has strong impact on human health in developed countries. In addition to workplace, people were usually exposed to passive smoking in their residence. The problem of active and passive smoking has potentially worsened in Taiwan since the government allowed tobacco import in 1987. This study examines smoker's impact on his indoor air quality and his relative's exposure to respirable suspended particulates ( RSP) and nicotine. The daily indoor/outdoor RSP and nicotine concentrations of six smoker's homes were concurrently measured over a week in a rural area of Taiwan in 1991. Personal exposure to RSP and nicotine of fourteen members from these six families were also measured. RSP was collected on PVC filters by personal pumps with cyclone ( flow rate= 1.91min-1). Nicotine was actively collected on tefloncoated glass fiber filters impregnated with sodium bisulfate, extracted by ammoniated heptane, and analyzed by GC/NPD. Indoor RSP concentrations (48.6±42.1 ug m-3) were higher than outdoor (26.4±15.2 ug m-3) in the summer. Indoor RSP concentrations (109.1±42.8 ug m-3) werehigher than outdoor (91.5±41.8 ug m-3) in the winter. Indoor nicotine concentrations of six homes were averaged at 0.7±0 .6 ug m-3 and personal exposure were about 0.5±0.5 ug m-3 in summer. Indoor nicotine concentrations of six homes were averaged at 0.7±1.1 ug m-3 and personal exposure were about 0.4±0.5 ug m-3 in winter. The RSP concentration difference between indoor and outdoor was positively correlated with the ratio of number of cigarettes smoked at homes divided by home volumes (r=0.55). The indoor nicotine concentrations were also positively correlated with the number of cigarettes smoked at homes in summer (r=0.49). The correlation coefficients between personal RSP measurements and indoor RSP measurements were 0.55 in the summer and 0.71 in the winter. The correlation coefficients between personal nicotine measurements and indoor nicotine measurements were 0.59 in the summer. The time-activity data of 8 non-smokers indicate that about 87% of their time were spent indoors. Relatives of smokers were most frequently exposed to passive smoking between 7 to 11 pm during the study period.#b0394013
