Variations in plant and soil lead and mercury content in a major Honolulu Park, 1972 to 1987, a period of significant source reduction

The Ala Moana beach and park area in SE Honolulu is exposed to (1) local automotive exhaust emissions from the heavily travelled boulevard and high density shopping mail located immediately to the north; (2) a frequently congested access road located between the park proper and the beach; and (3) a...

Description
Summary:The Ala Moana beach and park area in SE Honolulu is exposed to (1) local automotive exhaust emissions from the heavily travelled boulevard and high density shopping mail located immediately to the north; (2) a frequently congested access road located between the park proper and the beach; and (3) a remote source of geothermal and volcanic emissions 400 km to the SE on the Island of Hawaii. Between 1972 and 1987 both local Pb emissions and the more remote Hg emission fell by more than 80%. reductions in Pb reflected declining use of "leaded" gasoline; reductions in Hg reflected a declining output Hg super(0) vapor from volcanic and fumarolic sources.
