Children who are exposed to polychlorinated biphenyls (PCBs), which were commonly used in a range of industrial products, could be at risk of an increase in asthma symptoms, according to new research. The study will be presented in a poster discussion September 2, 2012 at the European Respiratory Society's Annual Congress in Vienna. PCBs were regularly used between 1930s and 1970s in a range of electrical equipment, lubricants and paint additives. They were eventually phased out due to the harm they were causing to the environment and animals.
