The coal-mining town of Fushun in China's Northeast is home to a monstrous open pit. First excavated in the early twentieth century, this pit grew like a widening maw over the ensuing decades, as various Chinese and Japanese states endeavored to unearth Fushun's purportedly "inexhaustible" carbon resources.
During coal mining activities, a lot of coal gangue is produced, which usually contains high mercury (Hg) concentrations as well as the acid mine drainage (AMD) generator of pyrite. In the present study, the total mercury (THg) and methylmercury (MeHg) in gangue, water, sediment, paddy soil, and rice samples, collected from abandoned coal …
