Transformation of logwood combustion emissions in a smog chamber: formation of secondary organic aerosol and changes in the primary organic aerosol upon daytime and nighttime aging

Publikováno v: Atmospheric Chemistry and Physics, Vol 16, Pp 13251-13269 (2016)

Organic aerosols (OA) derived from small-scale wood combustion emissions are not well represented by current emissions inventories and models, although they contribute substantially to the atmospheric particulate matter (PM) levels. In this work,

Experimental Assessment of the Short- and Long-Term Effects of 222Rn from Domestic Shower Water on the Dose Burden Incurred in Normally Occupied Homes

Autor: T. M. Raunemaa, B. Fitzgerald, V. K. Datye, P.K. Hopke, K. Kuuspalo

Publikováno v: Environmental Science & Technology. 31:1822-1829

Previous studies of the effects of 222 Rn in drinking water have centered on the long-term or chronic exposure to 222 Rn and its decay products. In this study, the possible effects that the transient increase caused by the release of 222 Rn from show

Age estimation of atmospheric black carbon over Finland from combined aerosol size distribution and radon progeny measurements

Autor: Taisto Raunemaa, Eduard Tamm, T. Ålander, K. Kuuspalo, Aadu Mirme

Publikováno v: Journal of Aerosol Science. 27:455-465

Data on aerosol particle size distributions between 0.01 and 10 um were combined with 222Rn and 210Pb particle activities to analyze black carbon characteristics. The activity ratio 210Pb/222Rn was applied to estimate the aerosol and black carbon age
