Application of the quartz crystal microbalance method for measuring mercury in the air of working environments involved to artisanal and small-scale gold mining (ASGM)

Artisanal small gold mining (ASGM) is responsible for approximately 40% of the total Hg emissions into the atmosphere worldwide. In developing countries, many people are engaged in ASGM activities. We developed a small, simple Hg measuring device, which detects Hg in the air based on the change of t...
