Human Rights Impacts of Mercury Pollution

This report by the Center for International Environmental Law examines the intersection of mercury pollution and human rights, detailing the neurotoxic effects of various forms of mercury and how these impacts violate the rights to life, health, food, and information, particularly for children and workers in artisanal mining.

• Mercury is a potent neurotoxin with no known safe exposure level, affecting all humans globally in trace amounts due to its environmental persistence. Exposure can occur via inhalation of metallic mercury vapor, which is 80 percent absorbed by the respiratory tract or sinuses, or through acute exposure to inorganic mercury salts that cause kidney and gastrointestinal damage.
• Fetuses and children are the most susceptible to mercury's developmental effects. Methylmercury consumption by mothers can lead to impaired neurological development in fetuses, affecting memory, attention, and motor skills. In the US, industrial mercury emissions are estimated to have reduced the IQ of between 300,000 and 600,000 children.
• Mercury pollution has caused catastrophic losses of life and permanent disability, notably in Minamata Bay, Japan, where wastewater from Chisso Corp. led to 'Minamata disease' characterized by brain atrophy and convulsions. A similar disaster occurred in 1970s Iraq, where the distribution of mercury-coated grain from the US and Mexico resulted in an estimated 10,000 deaths and 100,000 cases of permanent brain damage.
• Artisanal and small-scale gold mining (ASGM) creates severe health hazards for workers and communities. In Venezuela, airborne mercury concentrations in some areas reached a mean of 183 µg/m3, with 20 percent of measurements exceeding the NIOSH limit of 50 µg/m3. In Indonesia, studies found that 55 percent of amalgam smelters in Sulawesi and 62 percent in Kalimantan were diagnosed with chronic mercury intoxication.
• Mercury pollution threatens the right to food by contaminating fish and shellfish, which are primary protein sources for over 2.9 billion people. A US Geological Survey found mercury in all sampled predatory fish across 291 locations, with 27 percent exceeding the US EPA human health criterion of 0.3 micrograms of methylmercury per gram of wet weight.
• Lack of information and improper waste management lead to continued environmental release of mercury. In the Philippines, 88 percent of households dispose of mercury-containing lamps with domestic waste. Globally, the burning of mercury-added products in waste adds 200 tons of mercury to the atmosphere annually.
• Child labor in mining is a significant human rights violation, with up to 1 million children involved in mining globally. In Indonesia and Zimbabwe, children working in ASGM, some as young as 7, exhibited high levels of mercury in biomonitors and symptoms such as ataxia.
• The case of Thor Chemicals in South Africa illustrates the dangers of the global toxic trade. The firm used unskilled Zulu-speaking labor to manage imported mercury waste in Kwazulu-Natal, resulting in river pollution, worker deaths, and permanent disabilities, including one worker who could no longer talk or walk.
