leached from below detection limits to 0.175 mg/L. Arsenic, cadmium,
mercury, selenium, and silver were not detected. Identical
products (e-cigarette B) leached 20.5, 1.10, and 7.34 mg lead/L.
Replicates of e-cigarette D leached 0.22 and 0.97 mg lead/L as well
as 4.99 and 5.20 mg nickel/L. Eleven of the 23 e-cigarettes leached
undetectable amounts of lead. The pH of the extracts was mildly
acidic (pH 5.00–5.65), similar to the initial pH of the TCLP solution
(4.93 ± 0.05).
