Pollution Characteristics of Heavy Metals in PM₁ and Source-Specific Health Risks in the Tianjin Airport Community, China.

ABSTRACT: The airport and its surrounding areas are home to a variety of pollution sources, and air pollution is a recognized health concern for local populated regions. Submicron particulate matter (PM₁ with an aerodynamic diameter of <1 mm) is a typical pollutant at airports, and the enrichment of heavy metals (HMs) in PM₁ poses a great threat to human health. To comprehensively assess the source-specific health effects of PM₁-bound HMs in an airport community, PM₁ filter samples were collected around the Tianjin Binhai International Airport for 12 h during the daytime and nighttime, both in the spring and summer, and 10 selected HMs (V, Cr, Mn, Co, Ni, Cu, Zn, As, Cd, and Pb) were analyzed. The indicatory elements of aircraft emissions were certified as
