Mercury from Antarctic ice endangers marine life
A recent study reveals that the melting of Antarctic ice releases accumulated quantities of toxic mercury stored within it for decades, thereby increasing the risk of indirect pollution of marine environments. The research shows that the rate of mercury buildup in the area has become twice the global average, with a 160% increase since the late 19th century, due to industrial activity and rising temperatures. As the ice melts more rapidly, the ancient mercury trapped inside is released into the ocean, threatening marine food chains because it converts into a toxic compound known as "methylmercury," which accumulates in marine life and poses risks to human health and animals. The findings confirm that global warming could turn Antarctica into a new source of mercury pollution, which could enter a long cycle of contamination across both marine and terrestrial environments.
