A new research finding warns that Ghana cannot afford to delay the urgent need for stricter regulation of artisanal mining, improved environmental intelligence, and direct community health interventions, as the citizenry remains exposed to a cocktail of toxic metals.<\/p>\n

The year-long scientific study has uncovered alarming levels of mercury, arsenic, and other toxic metals in Ghana\u2019s small-scale gold mining (ASGM) areas, raising major public health and environmental concerns.<\/p>\n

The Mercury and Other Heavy Metals Impact Assessment (August 2024 \u2013 September 2025)<\/strong>, jointly conducted by Pure Earth<\/strong> and the Environmental Protection Agency (EPA)<\/strong>, examined soil, water, air, crops, and fish in mining communities across six regions: Ashanti, Western, Western North, Eastern, Central, and Savannah.<\/p>\n

Using the Toxic Sites Identification Programme (TSIP) methodology, researchers sampled more than a dozen sites, including Konongo Zongo, Prestea, Asiakwa, Osino, Bibiani, Dakrupe, and Wassa Kayianko.<\/p>\n

Laboratory testing revealed widespread contamination, with several hotspots far exceeding both Ghanaian and international safety thresholds.<\/p>\n

Mercury Contamination<\/strong><\/h3>\n

The Ashanti Region\u2019s Konongo Zongo recorded the highest soil mercury levels, with a mean concentration of 56.4 parts per million (ppm)<\/strong> \u2014 more than 560% above the safe guideline for playground soil (10 ppm)<\/strong> \u2014 and a maximum reading of 1,342 ppm.<\/p>\n

In the Western Region, air mercury levels at Wassa Kayianko averaged 1.84 \u00b5g\/m\u00b3<\/strong>, exceeding Ghana\u2019s permissible standard of 1 \u00b5g\/m\u00b3, with peak measurements reaching an extreme 150 \u00b5g\/m\u00b3<\/strong>, linked to gold smelting.<\/p>\n

While mercury in fish samples remained below World Health Organization (WHO) limits, experts warned that the limited sample size prevented conclusive safety assessments.<\/p>\n

Lead and Arsenic Risks<\/strong><\/h3>\n

The study also highlighted severe arsenic contamination<\/strong>. Konongo Zongo again stood out, with mean soil arsenic levels of 1,066 ppm<\/strong> and peaks as high as 10,060 ppm<\/strong> \u2014 about 4,200% above international safety thresholds<\/strong>.<\/p>\n

Arsenic levels in water at Konongo Odumase and Nyamebekyere were also dangerously elevated, with one sample recording 3.3 mg\/L<\/strong>, more than 300 times Ghana\u2019s drinking water limit of 0.01 mg\/L<\/strong>.<\/p>\n

Lead was found at worrying concentrations in both fish and crops. In Konongo Zongo, lead in fish reached 1.7 mg\/kg<\/strong>, surpassing the WHO\u2019s food safety guideline of 0.3 mg\/kg. At Akwaboso in the Central Region, fish samples contained even higher levels, up to 2.8 mg\/kg<\/strong>.<\/p>\n

Pumpkin leaves tested in the Western North Region also recorded lead concentrations of 3.1 mg\/kg<\/strong>, well above the accepted 0.1 mg\/kg threshold.<\/p>\n

Public Health Concerns<\/strong><\/h3>\n

The researchers concluded that communities in mining zones face serious health risks<\/strong> from multiple exposure pathways \u2014 contaminated soil, unsafe water, polluted air, and toxic food chains. Children, farmers, and miners are particularly vulnerable.<\/p>\n

The report warns that long-term exposure could increase risks of cancer, neurological disorders, kidney damage, and developmental problems in children.<\/p>\n
