Lead Pollution Detected in Tibetan Glacier Highlights Global Human Impact

Researchers, led by Dr. Franco Marcantonio from Texas A&M, have found evidence of lead pollution in a Tibetan glacier, highlighting the global impact of human activity. According to Nature.com, lead contamination began affecting the Guliya Ice Cap in 1974, with peak pollution levels from 2000 to 2007. The main source was emissions from leaded gasoline in China. This study reveals how pollution can spread even to remote areas like the Tibetan Plateau, posing potential risks to both ecosystems and human health. The research also sheds light on global atmospheric circulation patterns.
