... once commonly used by industry. The compounds are mixtures of 70-90 different molecular forms that vary in the number and positions of chlorine atoms, making them difficult to degrade. To date, the most commonly used method to remove PCBs from the environment is to dredge and then deposit the sediments in a ...Yale biologists 'trick' viruses into extinction
