Item Metadata only Kepekatan partikel ternafas (PM10) dan plumbum ternafas dalam udara ambien di kawasan bandar dan luar bandar(Penerbit UKM) Shamsul Bahari ShamsudinItem Embargo School indoor air pollutants: In relation to allergy and respiratory symptoms among school children in urban areas(University of Tehran, 2022) Zailina Hashim; Nur Shahira Mohamad Fadzil; Siti Raihan Mohd Fuad; Shamsul Bahari Shamsudin; Khairul Nizam Mohd Isa; Tan Tek Song; Jony Sieman; Saliza Mohd Elias; Jamal Hisham HashimIndoor air pollutants affect children's health and previous research mostly focuses on respiratory and allergic diseases. However, little is known about the risks among school children in East Malaysia. Therefore, we studied associations between school children's respiratory and allergic symptoms and indoor air pollutants in schools in Sabah, Malaysia. We randomly enrolled 332 school children (14 years old) from 24 classrooms in 6 secondary schools in Kota Kinabalu, Sabah. Information on personal characteristics, respiratory and allergic symptoms were gathered by using a standard questionnaire. The skin prick test was used to characterize the atopy. In each classroom, the indoor concentrations of particulate matter (PM10 and PM2.5), nitrogen dioxide (NO2), formaldehyde, total volatile organic compounds (TVOC), carbon dioxide (CO2) temperature and relative humidity were monitored.
