Nineteen samples of honey taken from grocery shelves, near zinc mines, adjacent to an industrial area, and near a major highway, and one sample collected in 1899 were subjected to spark source mass spectrometry to determine the concentration of most of 47 elements in the honey. Certain samples of honey produced by bees in the vicinity of the New York State Thruway appeared to contain elevated levels of certain elements known to be emitted by traffic, such as aluminum, barium, calcuim, copper, magnesium, nickel, palladium, and silicon, but the true source of these elements was uncertain. Honey that had come into contact with metal containers in processing contained the greatest amounts of zinc and tin.
Chromium concentration increased and molybdenum and tin concentrations decreased in Lake Cayuga lake trout (Salvelinus namaycush) from age 1 to 12 yr. The concentration of the rare element rhodium ranged from about 100 to 200 ppb. The concentrations of 33 other trace metals in the fish are reported.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
