High levels of environmental pollution may increase the rate of twin births, suggests a new study.
Industrial pollution from a toxic waste incinerator more than doubled the proportion of twins born to mothers living nearby, compared with those living in away from pollution in the Hesse region of Germany.
"The mothers of children in very polluted areas have had more twin births," says Nadia Obi-Osius, one of the team at the Ministry of Environment and Health and the Institute for Medical Biometry and Epidemiology in Hamburg, Germany.
