Misinformation about the presence of valuable “red mercury” in landmines has encouraged people to tamper with dangerous explosive ordnances. While not present in landmines, mercury, if not used correctly, can be harmful to people and has environmental impacts.
“Exposure to mercury could cause adverse health effects,” said Professor Nhachi. “It is toxic to plants and the soil as well. When it is in its organic form, it easily penetrates membranes in the body.”
He said that renal lesions are one of the symptoms of exposure to mercury, which injures the urinary system and can lead to death in the most extreme cases.
Small-scale miners continue to use mercury – not the mythical red mercury – to extract gold, a situation Masiya described as unfortunate given the health and environmental consequences that come with improper use. There are more than 400,000 people involved in artisanal small scale mining countrywide.
“Small scale miners use mercury because they believe it is the most effective way to mine gold. It is cheap and readily available; it costs about $150-$200 per kilogram; and there are no permits for purchasing the product,” Masiya said.
He said most small scale miners use their bare hands to separate mercury from the gold and when smelting gold over an open fire, resulting in them inhaling the toxic vapours.
