Increasing artisanal and small-scale gold mining (ASGM) in developing countries has raised health concerns in mining communities. A preliminary health survey was conducted in Thabeikkyin Township, Mandalay Region, Myanmar, in February 2020 to assess the health conditions of an ASGM community. Respiratory function and other Mercury (Hg) is one of the most harmful metals and has been a public health concern according to the World Health Organization (WHO). Artisanal and small-scale gold mining (ASGM) is the world’s fastest-growing source of Hg and can release Hg into the atmosphere, hydrosphere, and geosphere.

1. Introduction. Artisanal small-scale gold mining (ASGM), the source of approximately 20% of the world's gold, is the largest source of mercury (Hg) pollution on earth; contributing approximately 20–30% (Veiga et al., 2006; UNEP, 2005).Roughly10 to 19 million people use mercury to extract gold in more than 70 countries, making mercury medium-scale applications.

1. Introduction. In recent decades, gold mining expanded from its historical core (South Africa, the United States, Canada, Australia, and Russia) into a wide range of new gold mining regions, many of them located in the global South (Verbrugge and Geenen, 2020).In addition to the expansion of large-scale industrial mining, many of these regions Diamond and gold mining has been practiced by artisanal miners in the Central African Republic (CAR) for decades. The recent introduction of riverine dredges indicates a transition from artisanal/manual digging and sorting techniques to small-scale mining methods.
