摘 要:Black Carbon(BC) were measured continuously in rural area of Guanzhong Plain during winter and *** concentrations of BC varied acutely over a range of 3.9-25.6 μg m-3 for outdoor and 4.8-24.7 μg m-3 for indoor in daily mean concentration,with the overall average values of 14.6 μg m-3 and 14.4 μg m-3 for outdoor and indoor in winter,*** mean BC concentrations varied over a range of 2.9-9.9μg m-3 for outdoor and 4.7-10.2μg m-3 for indoor,with the overall average value of 6.0 μg m-3 and 7.2 μg m-3 for outdoor and indoor,respectively in *** results shows the concentrations of black carbon is high in the rural area,especially in winter,which is probably due to the local biomass burning for warming and *** rural area of Guanzhong Plain,Obviously diurnal variation of BC was observed,with the hourly average concentrations ascending to its peaks twice a day in the morning and at the *** frequency distributions of BC concentrations in both indoor and outdoor environments showed a similar *** indoor environment,it was found that the BC concentrations were distributed over the high spectrum of concentrations than that for outdoor *** relationships between indoor and outdoor concentrations(separately for LT,WN and HX sites) of BC were discussed,which showed a good correlation between indoor and outdoor air of the three *** results suggest that indoor black carbon was derived at least in part from outdoor air.
