"Breathing in any kind of air pollution can have an impact on our health, especially for those living with a lung condition. This study further confirms that air pollution can come from a range of sources, including from paints, adhesives and cleaning products we use indoors. Ensuring we keep our homes well ventilated, using liquid cleaners instead of sprays and checking that our cookers and heaters are in good working order will help protect us and prevent everyday products impacting on our lungs."
