The Global Impact: Over 23 Million People Affected by Metal-Mining Pollution

A recent study conducted by UK scientists has found that over 23 million people worldwide are living in areas contaminated by toxic waste from metal-mining activities. The scientists mapped both active and abandoned metal mines and calculated the extent of pollution caused by these mines. Chemicals from mining operations can seep into the soil and waterways, posing a significant threat to human health and the environment. The researchers emphasize the need for careful planning of future mines, especially considering the increasing demand for metals used in battery technology and electrification. The study also highlights the alarming impact of pollution from abandoned mines, which continues to affect millions of people. The scientists compiled data on mining activity from various sources and used this information to create a computer model, which estimates the extent of river channels and flood-plains contaminated by mining waste. The study reveals that contaminated soil and water can affect agriculture, irrigation, and livestock grazing in these areas. Crops grown on polluted soil and animals grazing on flood-plains may contain high concentrations of metals, posing risks to human health. Furthermore, the researchers predict that climate change and more frequent floods will exacerbate the issue of pollution from mining. The study underscores the importance of understanding how contaminants are transported in the environment and where they are stored, in order to assess and mitigate hazards. The findings shed light on the long history of environmental contamination caused by metal mining, which dates back thousands of years.
