Examination Of Exhaust Gas Emissions Of Transit Ships In The Istanbul Strait

Abstract

Scientific studies have showed that sulfur oxide, nitrous oxide, and particulate matter emissions emitted from ships have a direct harmful effect on human and environmental health. Approximately 30% (approximately 4/5 million) of the population of Istanbul city live about 3/4 km from the Istanbul Strait and are constantly exposed to air pollution (NOX, SOX, and PM emissions) occurring in the Istanbul Strait. In this study, transit ship traffic (43.541 ships) crossing the Istanbul Strait in 2015 was examined and the flue gas emissions generated by these ships were calculated as 18.324 tons of NOX, 2.138 tons of CO, 5.294 tons of SOX, 937.017 tons of CO2, 692 tons of PM and 693 tons of VOC. Emission results have been found at a high level and not at a negligible rate. With this study, the inventory of transit ship traffic emissions has been created. In addition to this marine emission inventory, it is very important to add and calculate the emissions caused by local ship traffic, motor vehicles, industry, and domestic warming in the Strait. The emission inventory will inform us about the air pollution that will occur in Istanbul for the coming years and the measures that can be taken in this area.

İstanbul Boğazı’nda Transit Geçiş Yapan Gemilerin Egzoz Gazı Emisyonlarının İncelenmesi

Abstract

Gemilerden salınan sülfür oksit, azot oksit ve partiküler madde emisyonlarının, insan ve çevre sağlığı üzerinde doğrudan zararlı etkisi yapılan bilimsel çalışmalarla ortaya konulmuştur. İstanbul ilinin nüfusunun yaklaşık %30’u (yaklaşık 4/5 milyon) İstanbul Boğazı’na yaklaşık 3/4 km mesafede yaşamaktadır ve Boğaz’da meydana gelen hava kirliliğine (NOX, SOX ve PM emisyonları) sürekli maruz kalmaktadır. Bu çalışmada, 2015 yılında İstanbul Boğazı’ndan geçiş yapan transit gemi trafiği (43.541 gemi) incelenmiş ve bu gemilerin ortaya çıkardığı baca gazı emisyonları 18.324 ton NOX, 2.138 ton CO, 5.294 ton SOX, 937.017 ton CO2, 692 ton PM ve 693 ton VOC olarak hesaplanmıştır. Emisyon sonuçları yüksek seviyede bulunmuş olup, ihmal edilebilecek bir oranda değildir. Bu çalışma ile transit gemi trafiği emisyonlarının envanteri çıkarılmıştır. Bu deniz emisyonu envanterinin yanında Boğaz’daki yerel gemi trafiğinin, motorlu taşıtların, sanayiin ve evsel ısınmanın da ortaya çıkardığı emisyonların hesaplanarak eklenmesi çok önemlidir. Emisyon envanteri, gelecek yıllar için İstanbul ilinde oluşacak hava kirliliği ve bu alanda alınabilecek tedbirler hakkında bize bilgi verecektir.
