Chemical components of respirable particulate matter associated with emergency hospital admissions for type 2 diabetes mellitus in Hong Kong

摘要

Background: Epidemiological studies have shown that short-termexposure to particulate matter (PM) mass is associated with diabetes morbidity and mortality, although inconsistencies still exist. Variation of chemical components in PM may have contributed to these inconsistencies. We hypothesize that certain components of respirable particulate matter (PM10), not simply PM10 mass, can exacerbate symptoms or cause acute complications for type 2 diabetes mellitus (T2DM).
