Britain's Toxic Air Scandal

One in three children in the UK are growing up inhaling unsafe levels of air pollution. Dispatches runs a world-first experiment to recude hundreds of primary school children's exposure to toxic air. Reporter, Morland Sanders reveals it's not just exhausts that produce dangerous emissions - for the first time we're shown previously unidentified toxins that are coming off every vehicle, even electric ones. Dispatches asks: is the Goverment doing enough to protect our children's health? Is the motor industry to blame? And what can we do to prevent dangerous exposure to children now?
