Ambient metals, elemental carbon, and wheeze and cough in New York City children through 24 months of age.

ABSTRACT:

Rationale

The effects of exposure to specific components of ambient fine particulate matter (PM(2.5)), including metals and elemental carbon (EC), have not been fully characterized in young children.

Objectives

To compare temporal associations among PM(2.5); individual metal constituents of ambient PM(2.5), including nickel (Ni), vanadium (V), and zinc (Zn); and EC and longitudinal reports of respiratory symptoms through 24 months of age.
