Greenpeace called on the Labour Party to ban rubbish incinerators and abandon plans for up to 100 new plants, after medical research published in The Lancet showed that toxic fumes from incinerators could be having alarming effects on the sexual development of children. The study found that teenagers living near incinerators had smaller sexual organs than those in rural areas. The teenagers' bodies contained high levels of toxic chemicals, which are thought to interfere with sexual development and are already linked to cancer, heart disease, allergies and breathing illnesses.
