Influence of ship emissions on ozone concentrations around coastal areas during summer season

Emissions of Ozone Precursors from a Biogenic Source and Port-related Sources in the Largest Port City of Busan, Korea

“…The contribution of biogenic isoprene emission to ozone concentration was up to 37 ppb in Seoul region. Ozone concentration in inland area and coastal area of Busan is known to be sensitive to VOCs and NOx levels, respectively (Song et al, 2010). Meanwhile, the lifetime of ozone in troposphere is about 3 weeks varying with altitude and that in the boundary layer is about 1-2 days (Stevenson et al, 2006).…”

“…In addition, local ship emissions in coastal areas including ports have contributed to the increase in O 3 concentrations around these areas (e.g. up to 29 ppb in the South Coast of California (Vutukuru and Dabdub, 2008) and 15 ppb in a coastal port city of Korea (Song et al, 2010)). As a target city, Busan has the world's fifth busiest container port according to the cargo tonnage (known as "Cargo Gateway of Asia") and the best transshipment port in Northeast Asia.…”

Characteristics of Ozone Precursor Emissions and POCP in the Biggest Port City in Korea

“…Thus, ozone formation in inland areas of Busan was likely to be sensitive to VOCs due to high NO x emissions. It was found that ozone formation in coastal region of Busan was sensitive to NO x , whereas that in downtown area was sensitive to VOCs (Song and Shon, 2010). In order to assess the effects of annual emission rates of ozone precursors NO x and VOCs and emission ratio of VOCs to NO x , multiparametric relationship (multiple regression analysis) were carried out.…”

“…Changes in the emissions of ozone precursors from on-road mobile sources in various atmospheric environments are highly sensitive to ozone formation (Song et al, 2012). Ozone formation in urban areas such as New York, Los Angeles, and Seoul is typically sensitive to VOC concentration, but that in rural (and suburban) and coastal areas is sensitive to NO x concentration (Song et al, 2012(Song et al, , 2010Kim, 2011;Steiner et al, 2006;Kleinman et al, 2000). In contrast, ozone production was reported to be sensitive to NO x concentration in Atlanta, Gerogia .…”

“…(Song et al, 2010;Song and Shon, 2008). 이러한 O 3 생성 및 민감도 분석 연구는 대류권 O 3 의 광화학을 이해하는 데 크게 도움을 줄뿐만 아니라 (Cantrell et al, 2003a;Kleinman et al, 1997;Jacob et al, 1996), 대 도시 오염지역에서 O 3 생성과정 이해 및 고농도 O 3 저감정책 수립을 위한 중요한 정보를 제공해준 다 (Daum et al, 2003;Kleinman et al, 2002;Thornton et al, 2002).…”
