PCB Found in Sediment Samples of Deep-Sea Trench
Researchers have found polychlorinated biphenyls (PCB) in samples of sediment sourced about 8,000 meters deep in the Atacama Trench, a deep-sea trench in the Pacific Ocean about 100 miles (160 kilometers) off the coasts of Peru and Chile. Despite bans spanning back to the 1970s, PCB remains are still threatening the environment. New research, published […]
