Koror and Airai have the highest populations in Palau with more development (roads, residential development and
industry). By comparison, Kayangel and Ngarchelong have small populations and very limited pollution. Loss of fish
catch from terrestrial pollution for Hatohobei and Sonsorol, two states with minimal population and negligible development, is assumed to be zero, and they are not included in the estimates.
