Abstract: | Indoor and outdoor particulate matter (PM0.3-10) number concentrations were established in two medieval churches in Cyprus. In both churches incense was burnt occasionally during Mass. The highest indoor PM0.5-1 concentrations compared with outdoors (10.7 times higher) were observed in the church that burning of candles indoors was allowed. Peak indoor black carbon concentration was 6.8 μg m−3 in the instances that incense was burning and 13.4 μg m−3 in the instances that the candles were burning (outdoor levels ranged between 0.6 and 1.3 μg m−3). From the water soluble inorganic components determined in PM10, calcium prevailed in all samples indoors or outdoors, whilst high potassium concentration indoors were a clear marker of combustion. Indoor sources of PM were clearly identified and their emission strengths were estimated via modeling of the results. Indoor estimated PM0.3-10 mass concentrations exceeded air quality standards for human health protection and for the preservation of works of art. |
