Enhancement of arsenic mobility by indigenous bacteria from mine tailings as response to organic supply
JU Lee, SW Lee, HT Chon, KW Kim, JS Lee - Environment International, 2009 - Elsevier
Arsenic leaching by indigenous bacteria in abandoned Au–Ag mine tailings which
contained approximately 3200 mg/kg of As was investigated after supply of various organic
substrates. Sequential extraction analysis designed to determine the mode of As occurrence
in the tailings revealed that most As (90%) was closely associated with the Fe fraction. When
glucose was supplied as a C source, indigenous bacteria significantly enhanced the extent
of As release from the tailings into solution under both aerobic and anaerobic conditions …
