Northern hemispheric organic lead emissions in fresh Greenland snow
International audience Ionic alkyllead species have been determined in fresh or slightly aged surface snow from Greenland relying on ultraclean sampling, high-resolution separation of individual species, and ultrasensitive determination procedures. The samples were collected from January to August 1...

International audience Ionic alkyllead species have been determined in fresh or slightly aged surface snow from Greenland relying on ultraclean sampling, high-resolution separation of individual species, and ultrasensitive determination procedures.
