Sargasso Sea lead levels drop



Concentrations of lead in the Sargasso Sea have decreased since at least 1979, following the phase-out of leaded gasoline in the United States that began in the early 1970s, according to a group of three scientists at the Massachusetts Institute of Technology (MIT). The Sargasso Sea is an area of the western North Atlantic Ocean centered near Bermuda, extending from about 20° to 40°N (from about the latitude of Cuba to about the latitude of North Carolina). This work will be presented on Friday morning, December 12, at the 1986 AGU Fall Meeting/ASLO Winter Meeting in San Francisco (Eos, November 4, 1986, p. 1066).
