Abstract

Ultrafine partilces (UFP) has become important concerns of people due their identified impacts on human health. The contribution of UFP on indoor air quality (IAQ) is another thing that attracts an attention for investigation. This study performs the measurements of outdoor indoor UFP concentrations in lecture rooms. The aims were to measure the UFP concentrations in the lecture rooms, and also to estimate the relationships between outdoor UFP concentrations and indoor UFP concentrations. The results showed that the UFP concentration in the lecture rooms varied between 1.0 x 103 particles/cm3 and 4.1 x 103 particles/cm3. The indoor UFP concentrations were found proportional to the outdoor UFP concentrations. And I/O UFP concentration ratio was obtained more than 80 %.

Abstract

ABSTRAK Penelitian ini bertujuan untuk identifikasi komponen PAH dan   partikulat   dari   emisi   kendaraan   bermotor. Penangkapan komponen PAH dan partikulat dari emisi kendaraan bermotor menggunakan Whatman Filter Paper PM10 selama 60 menit. Selanjutnya Whatman Filter Paper PM10 diisolasi menggunakan soxhlet selama 10 jam dengan menggunakan pelarut diklorometana. Ekstrak yang diperoleh dipekatkan dengan gas nitrogen, Kemudian dipisahkan dengan kromatografi kolom dan  dikarakterisasi menggunakan kromatografi lapis tipis. Sampel dianalisis menggunakan Kromatografi Gas Spektroskopi Massa (KG-SM). Hasil dari emisi kendaraan bermotor  menunjukkan adanya beberapa komponen PAH yang sebagian besar terdiri dari C-(3-Vinyl-benzo[ghi]fluoranthen-4-yl)-methylamine, 3-Methyl-1,2,3,4-tetrahydro-anthracen-2-ylamine, and C-(3-Vinyl- naphthalen-2-yl)-methylamine. Kata kunci: PAH, Partikulat, Soxhlet, KG-SM. ABStract This study was aimed to identify PAHs componds in PM10 emitted by motor cycles. The PM10 particulates were trapped by a whatman filter paper PM10 for 60 minutes. The filter was isolated using soxhlet extraction for 10 hours with dichloromethane solvent, the solution was extracted by a nitrogen gases. Then the solution was separated using a column chromatography and characterized using thin layer chromatography. Finally the samples was analyzed using a GC-MS. The results showed that the PM10 emission from motor cycles contained of a several PAHs with the relativity large amount of C-(3-Vinyl-benzo[ghi]fluoranthen-4-yl)-methylamine, 3-Methyl-1,2,3,4-tetrahydro-anthracen-2-ylamine, and C-(3-Vinyl-naphthalen-2-yl)-methylamine. Keywords: PAH, Particulate Matter, Soxhlet, GC-MS
