Organic and black carbon in PM2.5 and PM10: 1 year of data from an urban site in Helsinki, Finland

A wintertime study of polycyclic aromatic hydrocarbons in PM2.5 and PM2.5–10 in Beijing: Assessment of energy structure conversion

“…Carbonaceous species of particulate matter is often recognized as important contributors to aerosol-related consequences, including visibility, climate and human health [1]. It was reported that about one-third of total PM 2.5 mass in Beijing was constituted by organic carbon [2].…”

“…We focused on sources and spatial distribution of PAHs. The objectives of this study are: (1) to give the PAHs levels of PM in Beijing, (2) to identify the most polluted area and the health risk of PAHs in these city area, (3) to assess the effects of new energy strategy and (4) to give an advice on PAHs controlling.…”

Elemental Composition of Atmospheric Particles during Periods with and without Traffic Restriction in Beijing: The Effectiveness of Traffic Restriction Measure

“…All of these have caused the already-polluted air to become even more polluted. For example, the PM 10 mass concentrations in Beijing were much higher than those in Helsinki and Los Angeles, the two previous Olympic-host cities (Viidanoja et al 2002;Wang et al 2000;Li et al 2006). It was once reported that the hourly average PM 10 mass levels were as high as 400 µg m −3 in urban areas of Beijing (Shi et al 2003).…”

Levoglucosano e íons solúveis em água no material particulado atmosférico MP10 e MP2,5. caracterização de sítios Sul-Americanos

“…Ao passo que o carbono orgânico (CO) pode ser de origem primária ou secundária, dependendo da proximidade da fonte, das atividades fotoquímicas e do tempo de permanência do aerossol (Viidanoja et al, 2002;Favez et al, 2009). …”

“…O CO tem origem primária e secundária. No particulado grosso sua presença é atribuída a fontes primárias, como a emissão de matéria orgânica do solo, de pneus e pólen de plantas (Viidanoja et al, 2002; Rastogi e Sarin, 2009).…”
