This study relates to the pulmonary function of school age children and the air quality of public transport in Hong Kong. It focuses on selected primary five or six students from schools in Hong Kong. A log book and a questionnaire were distributed through the schools to and completed by these students. Each sampled student had to fill in the daily travelling activities and also required to answer questions related to their indoor living conditions. The sampled students were required to conduct a pulmonary function test. The air pollutants such as PM10, PM2.5, CO2, CO and Volatile Organic Compounds (VOCs) were measured following the routes to school and return home of sampled students. A statistical analysis, ANCOVA, was performed on the modes of transportation and the lung function test results. It was found that different modes of transportation have significant difference on the student’s lung function. It was also found that students who go to school by Mass Transit Railway (MTR) had significant better pulmonary function values than any others. Statistical regression was further applied to quantify the effect of different parameter to pulmonary function.

İlköğretim Öğrencilerinin Günlük Ulaşım Aktivitesindeki Hava Kirliliğine Maruz Kalması ile Sağlığa Etki Göstergesi Arasındaki İlişkinin Araştırılması

Öz

Bu çalışma, okul çağındaki çocukların solunum fonksiyonları ve Hong Kong'daki toplu taşıma araçlarının hava kalitesi ile ilgilidir. Hong Kong'daki okullarda eğitim gören rassal beş - altı öğrenci seçilmiştir. Verilerin toplanması, ilgili öğrencilere okullar aracılığıyla kayıt defteri ve anket dağıtılarak tamamlanmıştır. Katılımcı öğrencilerin her birinden günlük seyir aktivitelerini doldurmaları ve iç mekânda geçen yaşam koşullarıyla ilgili soruları cevaplamaları istenmiştir. Öğrencilere ayrıca Solunum Fonksiyon Testi uygulanmıştır. Öğrencilerin okula gidiş ve okuldan eve dönüş güzergâhlarındaki PM10, PM2.5, CO2, CO ve Uçucu Organik Bileşikler (VOCs) gibi hava kirleticilerinin seviyesi ölçülmüştür. Taşıma türleri ve akciğer fonksiyon test sonuçlarının istatistiksel analizi için ANCOVA’ya başvurulmuştur. Raylı Toplu Taşıma Sistemi (MTR) ile okula giden öğrencilerin Solunum Fonksiyon Testi sonuçlarının diğerlerinden daha iyi olduğu sonucuna ulaşılmıştır. Ek olarak, farklı parametrelerin solunum fonksiyonu üzerindeki etkisini ölçmek için regresyon uygulanmıştır.
