Cobalt is usually not mined alone, and tends to be produced as a by-product of nickel and copper mining activities. The main ores of cobalt are cobaltite, erythrite, glaucodot, and skutterudite. The world's major producers of cobalt are the Democratic Republic of the Congo, mainland China, Zambia, Russia and Australia.Child miners aged four at Congo cobalt mine | Daily Mail Online Cobalt is such a health hazard that it has a respiratory disease named after it – cobalt lung, a form of pneumonia which causes coughing and leads to permanent incapacity and even death .Democratic Republic of Congo: "This is what we die for . Despite the potentially fatal health effects of prolonged exposure to cobalt, adult and child miners work without even the most basic protective equipment. This report is the first comprehensive account of how cobalt enters the supply chain of many of the world’s leading brands.Mining health and safety: 7 common risks to protect yourself . “Understanding and being aware of your environment is the first step to preventing illness or injury in the workplace,” reveals mining medicine researcher Megan Clark, who outlines the following 7 common health risks to watch out for in the mining industry. 1.

Graphite in China There’s a trace of graphite in many of .Cobalt | Co - PubChem Cobalt is normally associated with copper or nickel; mined ore often contains only 0.1% elemental cobalt. About 44% of world production of cobalt comes from nickel ores. Cobalt is extracted from the metals in the ore by both flotation (sulfide ores) and gravity (arsenide ores); roasting or acid leaching is necessary to concentrate the cobalt.Radiation | Nuclear Radiation | Ionizing Radiation | Health . N.B. Though the intrinsic radioactivity is the same, the radiation dose received by someone handling a kilogram of high-grade uranium ore will be much greater than for the same exposure to a kilogram of separated uranium, since the ore contains a number of short-lived decay products (see section on Radioactive Decay), while the uranium has a very long half-life.The secret on the ocean floor - BBC News Last year Amnesty International said there were children as young as seven working in the DRC’s cobalt mines, “in narrow man-made tunnels, at risk of fatal accidents and serious lung disease”.

A naturally occurring, homogeneous inorganic solid substance having a definite chemical composition and characteristic crystalline structure .Heavy Metals Toxicity and the Environment Introduction. Heavy metals are defined as metallic elements that have a relatively high density compared to water .With the assumption that heaviness and toxicity are inter-related, heavy metals also include metalloids, such as arsenic, that are able to induce toxicity at low level of exposure .Arsenic (As) - Chemical properties, Health and Environmental . World production of arsenic, in the form of its oxide, is around 50.000 tonnes per year, far in excess of that required by industry. China is the chief exporting country, followed by Chile and Mexico. World resources of arsenic in copper and lead ores exceed 10 million tonnes. Health effects of arsenicThe toll of the cobalt mining industry on health and the . Health risks of chronic exposure . According to the CDC, "chronic exposure to cobalt-containing hard metal (dust or fume) can result in a serious lung disease called 'hard metal lung disease .

Sativa Wellness Group Inc said new research suggests cannabinoids may help treat inflammatory lung disease.. The paper follows collaboration with King’s College London and includes the results of an investigation on the potential therapeutic use of cannabinoids for the treatment of respiratory diseases.The dirty secret of electric vehicles | World Economic Forum Amnesty points to serious health risks to child and adult workers in cobalt mines in the Democratic Republic of Congo, documented in a report it issued. More than half the world’s cobalt comes from southern DRC, much of it from artisanal mines that produce 20% of the country’s output.Lung cancer risk | Cancer Research UK Lung cancer risk overall is associated only with PM2.5 (9% higher risk per 10µg/m3); the association with PM10 is not significant (95% CI 1.00-1.17). Lung adenocarcinoma is less closely linked with smoking compared with other lung cancer types. Lung cancer death risk is higher in people living near major roads, a meta-analysis showed.
The health community can take action to reduce adverse health effects from e-waste by building health sector capacity to diagnose, monitor and prevent toxic exposure among children and women, raising awareness of the potential co-benefits of more responsible recycling and advocating for better data and health research on the health risks faced .Child labour, toxic leaks: the price we could pay for a .
