The study has been conducted in 9 sites mainly main road throughout Kota Kinabalu. The sites are Cross junction at Damai Road, Jalan Lama junction with road to Luyang, Sembulan Roundabout, Wisma Perkasa Roundabout, Tamu KPD, Perindustrian Roundabout, Masjid Bandaraya Roundabout, Anjung Selera and Kingfisher Roundabout. Each site consists of 3 replicate samples. The sampling was conducted in between the month of January and February. The dust extract was analyzed by means of flame atomic absorption spectrophotometry (AAS) using 2-5000 Polarized Zeeman Atomic Absorption Spectrophotometer at a wavelength of 228.8 nanometer for cadmium and 357.9 nanometer for chromium. Cadmium concentration for 9 site ranging between 0.01-0.1 µg/g and chromium concentration is varied between 0.4-3.8µg/g. From the result obtained, it is clear that there are significant correlations between cadmium against chromium with Pearson correlation value of 0.692, cadmium against traffic volume with value of 0.662 and chromium against traffic volume with value of 0.584.
