Rising mercury pollution in soil could be related to climate change, study says
A study published in ACS’ Environmental Science & Technology estimates that soil stores substantially more mercury than previously thought, and it predicts that increases in plant growth due to climate change may add even more.
Metal Contamination Causes Metabolic Stress in Environmental Bacteria
Most studies on the effects of heavy metals on bacteria living in these environments have only focused on one metal at a time. In this study, researchers found that exposing bacteria to a mixture of metals caused their metabolism to change and led them to act as if they were starved for iron.
Adsorbent material filters toxic chromium, arsenic from water supplies
Researchers at the Department of Energy’s Oak Ridge National Laboratory are tackling a global water challenge with a unique material designed to target not one, but two toxic, heavy metal pollutants for simultaneous removal.
