Abstract

âº PM chemical composition may better predict health effects than PM mass or size. âº We reviewed 29 studies that attempted this by using apportionment methods. âº Were specific sources or factors consistently linked to specific health effects? âº Apportionment methods have identified links, but we found little if any consistency.
