“…The Hg concentrations in the sampled groundwater were in the range of 0-0.04 µg/L. The area closest to gold-mining activities typically showed Hg contamination [35]. The samples obtained in the Irrawaddy River, which was downstream from the ASGM area, showed a Hg concentration of 0.005 µg/L Hg, and samples taken from the upper stream of the river contained 0.004 µg/L of Hg.…”

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. Hg has been widely used in ASGM industries throughout Southeast Asia countries, including Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, and Thailand. Here, 16 relevant studies were systematically searched by performing the PRISMA flow, combining the keywords of “Hg”, “ASGM”, and relevant study areas. Mercury concentrations exceeding the WHO and United States Environmental Protection Agency guideline values were reported in environmental (i.e., air, water, and soil) and biomonitoring samples (i.e., plants, fish, and human hair). ASGM-related health risks to miners and nonminers, specifically in Indonesia, the Philippines, and Myanmar, were also assessed. The findings indicated severe Hg contamination around the ASGM process, specifically the gold-amalgamation stage, was significantly high. To one point, Hg atmospheric concentrations from all observed studies was shown to be extremely high in the vicinity of gold operating areas. Attentions should be given regarding the public health concern, specifically for the vulnerable groups such as adults, pregnant women, and children who live near the ASGM activity. This review summarizes the effects of Hg in Myanmar and other Southeast Asian countries. In the future, more research and assessment will be required to investigate the current and evolving situation in ASGM communities.

“…While no parts were removed from the vegetable samples, the husks were excluded from the rice samples. Removing the husks could result in a lower Hg concentration since the grains generally have lower Hg levels compared to the roots and husks (Enamorado-Montes et al, 2021).…”

“…The ASGM sector accounts for about 69.7% of the total national Hg released into the environment (about 244 tonnes) in Indonesia (BaliFokus, 2018). Hg concentrations in air, river water, soil and fish around ASGM sites have been investigated in several areas; including Central Kalimantan (Elvince et al, 2008), Gorontalo (Mallongi et al, 2014), North Sulawesi (Limbong et al, 2003), Java (Iqbal and Inoue, 2011) and West Java (Yustiawati et al, 2006;Harianja et al, 2020) in Indonesia. Hg pollution has been investigated in detail in West Java and high Hg concentrations in river water, soil and air near ASGM sites have been reported (Yustiawati et al, 2006;Yasuda et al, 2011;Kono et al, 2012;Kono and Tomiyasu, 2013;Tomiyasu et al, 2013Tomiyasu et al, , 2019.…”

Artisanal small-scale gold mining (ASGM) is the largest single source of mercury (Hg) emissions globally. In this study, Hg contamination was investigated in rice, vegetables, soil, drinking water and groundwater near ASGM sites in Mandailing Natal District, North Sumatra, Indonesia to assess the human health risk of Hg to the residents. The mean Hg concentrations in the rice and vegetables were 50 ± 33 μg/ kg dw (n = 20) and 2,100 ± 2,500 μg/ kg dw (n = 12), respectively, and that in the paddy soil and farm soil were 5,600 ± 12,000 μg/ kg dw (n = 20) and 19,000 ± 33,000 μg/ kg dw (n = 12), respectively. Hg concentrations in the food, soil and drinking water samples decreased significantly with increasing distance from the amalgam burning facility to the sampling site, suggesting that the burning facility is a major source of Hg in this area. All drinking water samples were below the WHO safe value of Hg, whereas 96% of the vegetable and 82% of rice samples exceeded the safe value from the Indonesian National Standard or the FAO/WHO. The non-cancer risk calculated from the hazard quotients for the rice and vegetables exceeded 1 for children and adults. This paper provides information on Hg contamination in food and the environment in an understudied area, employing health risk assessment to evaluate long-term impacts on human health and offering insights for government decision-making regarding food quality.
