Temperature effect on seawater leaching of Pb, Zn, and F from waste rock at Ivittuut cryolite mine in South GreenlandNARA Subscribed
Pollution from mining waste poses environmental risks and can adversely impact nearby communities. Understanding the weathering processes of mining waste and pollutant release is crucial for effective environmental remediation. At Ivittuut, South Greenland, cryolite was mined for 130 years. Waste rock (WR) from the mine was disposed of along the coastline of Arsuk Fjord. The WR contains sulfides such as pyrite (FeS 2 ), galena...
Immobilization of Pb and Zn leached from waste rock (WR) using shrimp shells, waste concrete, and sea water was investigated in continuous flow column leaching tests. To evaluate dynamic long-term leaching behaviors, leachate was collected at different liquid/solid (L/S) ratios up to 10 L/kg (≈ 12 weeks). The results showed that the leached content of Pb, Zn, Ni, Cu, Cd, and As from the WR control treatments generally decrease...
Public concerns over presumed metal and radionuclide pollution: testing a possible link to ovine hepatic melanosis in South GreenlandNARA Subscribed
In South Greenland, public concerns have linked “black livers” in sheep to presumed environmental pollution from the Kvanefjeld mining exploration project. Elevated concentrations of metals and radionuclides in the area reflect natural geochemistry and weathering processes, not pollution from exploration activities. However, in response, we conducted a preliminary case–control study to diagnose the condition, investigate links...
Seventy five percent of the world's food crops benefit from insect pollination. Hence, there has been increased interest in how global change drivers impact this critical ecosystem service. Because standardized data on crop pollination are rarely available, we are limited in our capacity to understand the variation in pollination benefits to crop yield, as well as to anticipate changes in this service, develop predictions, and...
