The objective of the study was to identify risk factors and describe outcomes for children newly identified with blood lead levels (BLLs) ≥45 µg/dL in New York City (NYC) during 2004-2010 to promote timely identification as well as inform clinical practice and public health policy.

Anthropogenic emissions completely overwhelmed natural marine lead (Pb) sources during the past century, predominantly due to leaded petrol usage. Here, based on Pb isotope measurements, we reassess the importance of natural and anthropogenic Pb sources to the tropical North Atlantic following the nearly complete global cessation of leaded petrol use. Significant proportions of up to 30–50% of natural Pb, derived from mineral dust, are observed in Atlantic surface waters, reflecting the success of the global effort to reduce anthropogenic Pb emissions.
