The Ministry of Health in both the Solomon Islands and Fiji and the Pacific Regional Office of the World Health Organization acknowledges that air pollution and health is a concern.  There is a knowledge gap in this space hence my study will contribute to bridging this gap.  My research aims to achieve the following.  (1) to measure size fractions of airborne particulates over time and seasons noting unique trends; (2) measure the organics and metals in PM2.5 to determine sources risk assessment; and (3) measure school children’s exposure and understanding household behavior.  My findings will inform governments and interested parties.
