The seasonal variation of atmospheric mercury was significant, with concentrations rising five to seven times higher during autumn compared to winter, and its isotopic composition also demonstrated seasonal fluctuations. From the distinctive isotopic fingerprints of potential mercury sources and the trajectory of air masses, we conclude that underground coal fires are still releasing considerable amounts of mercury into the atmosphere that is subsequently carrie
