Pb and Sr Isotopic Compositions of Soils in Urbanized Industrial Settings, East Los Angeles, California, U.S.A: From Geogenic to Anthropogenic Sources

Autor: Robert Ayuso, Nora Foley, Jill Johnston, Rani Indela, John Jackson, Damon Bickerstaff

Preliminary lead and strontium isotopic compositions of soil profiles collected from highly urbanized and industrialized sites were measured to develop a survey of possible sources of lead. Potential lead and strontium sources range from geologic (e.

Products of oxidative dissolution on waste rock dumps at the Pb-Zn Rudnik mine in Serbia and their possible effects on the environment

Autor: Zdravković Alena, Cvetković Vladica, Pačevski Aleksandar, Rosić Aleksandra, Šarić Kristina, Matović Vesna, Erić, Suzana

Publikováno v: Journal of Geochemical Exploration

Waste material from two active and two abandoned waste rock dumps from the Pb-Zn Rudnik Mine (central Serbia) was studied by optical, scaning microscopy, and X-ray powder diffraction methods. The weathering minerals in the active dumps are represente
