Ofis Ortamında Çalışanların İç Hava Kalitesine Maruziyeti ve Sağlıkla İlişkisi

Öz

İnsanlar zamanlarının yaklaşık yüzde 80-90'ını kapalı alanlarda geçirdiklerinden, iç hava kalitesi (IAQ) büyüyen bir endişe kaynağıdır. Ofis binalarındaki IAQ insanların sağlığını etkilediği bilinmektedir. İş bulma kurumları, her gün 1000'den fazla kişinin ziyaret ettiği ve görüşme yaptığı en önemli kurumlardan biridir. Personel ve binaya gelen ziyaretçilerin maruz kaldığı iç hava kalitesi değerini değerlendirmek için ölçümler yapılmış ve bulgular WHO and ARSHAE standartlarla karşılaştırılmıştır. Personel maruziyetlerini anlamak ve sağlık üzerindeki etkilerini belirlemek için iki anket uygulandı. Değerler ortalama PM10 67,73 μg/mᶾ; PM2.5 35.95 μg/mᶾ ve gürültü 67 dBA bulundu, bu değerler sağlık açısından risk oluşturabilir. İlk anket katılımcıları iç hava kirleticilerinin maruziyetini ölçmek içindi; havalandırmanın sıklıkla yetersiz (% 42) ve ofis ortamının her zaman gürültülü (% 57) olduğunu bildirdiler. İkinci ankette katılımcılar boğaz kuruluğu (% 42), gözde sık sık yaşarma ve kızarıklıktan (% 60) şikayet ettiler. Bina, havalandırması ve kliması olmayan eski bir bina olup, elde edilen sonuçlardan sorumlu olduğu düşünülen yalıtım sistemi olmadan açık ofis sistemi kullanılmaktadır.

Exposure of Indoor Air Quality in Office Environment to Workers and its Relationship to Health

Öz

Indoor air quality (IAQ) is a growing concern, as people spend about 80–90 percent of their time indoors.It is known that IAQ in office buildings influences people’s health. Employment agencies are one of the most important institutions,where more than 1000 people visit and hold interviews everyday. Measurements were made in order to assess the IAQ that staff and visitors to the building are exposed to,and the findings were compared to WHO and ARSHAE standards.Two questionnaires were applied to the staff to have an insight into their exposure and determine its effects on health.The mean PM10 was found to be 67.73 μg/mᶾ; PM2.5 was 35.95 μg/mᶾ and sound was 67 dBA, which may pose risks for health. The first questionnaire was to measure the exposure of indoor air pollutants to individuals, who reported that ventilation is frequently inadequate (42%) and the office environment is always noisy (57%). In the second questionnaire, the participants complained of dry and sore throat (42%), frequent tearing and redness in eyes (60%). The building is an old one with a lack of ventilation and air conditioning,and an open office system is used without insulation system,which are all considered to be responsible for the obtained results.
