Heavy Metal Contamination in Global Farmland: A Shocking Revelation

A groundbreaking study published in Science reveals alarming levels of heavy metal contamination in global farmland. Researchers analyzed nearly 800,000 soil samples, finding that up to 17% of cropland contains excessive amounts of arsenic, cadmium, chromium, cobalt, copper, nickel, and lead. The contamination, stemming from both natural processes and human activities like fertilizer use and industrial emissions, affects an estimated 900 million to 1.4 billion people. A ‘metal-rich corridor’ spanning densely populated regions from Europe to India highlights the long-term impact of human activities, dating back to ancient civilizations. The study emphasizes the urgent need for stricter soil standards to safeguard ecosystems and public health.
