The absorption coefficient (α) was measured on the collected filters, as a surrogate for EC concentration levels. Ambient PM levels were very high at both central sites and significant at SR (mean 24-hr PM10: 87.4, 50.3 and 87.3 μg m-3 and PM2.5: 50.7, 20.2 and 42.8 μg m-3 at CR, SR and CO). The measured absorption coefficient values were very high at CR and CO for both size fractions. Indoor PM concentration and absorption coefficient values were lower than the respective outdoor ones, but still significant at the two central sites. Very good correlations were observed between indoor and outdoor data (especially for absorption coefficient values), indicating a large contribution of the ambient atmosphere to the indoor levels, more pronounced in finer particles.</p></abstract><publication_date><month>04</month><day>30</day><year>2013</year></publication_date><pages><first_page>12</first_page><last_page>19</last_page></pages><publisher_item><identifier id_type="pii">693</identifier></publisher_item><doi_data><doi>10.30955/gnj.000693</doi><timestamp>1713555244</timestamp><resource>https://journal.gnest.org/publication/693</resource></doi_data></journal_article></journal></body></doi_batch> </div>
