Pollution may increase risk of miscarriage

Diesel exhaust fumes can cause harm to embryo

Toxic traffic fumes can increase the risk that women will miscarry, researchers have warned.
The dirty air created by the vehicle output stunts the growth of embryos and can result in early pregnancy loss, new research suggests. They said that women should avoid getting pregnant when there were high levels of pollution in the air.
While this did not stop the embryo implanting in the womb it did cause development problems, increasing the risk that the women would go on to miscarry by up to two and a half times.

Dr Paulo Marcelo Perin, from the University of Sao Paulo, in Brazil, part of the team which carried out the study, said: ‘Our recommendation would be to not get pregnant when you have high levels of pollution.’

Around one in 10 pregnancies in Britain ends in miscarriage.

A second study estimates that being exposed to high levels of air pollution can cut a woman’s chance of successful IVF by the same rate as being a year older. Researchers at Penn State College of Medicine in Pennsylvania found that high levels of traffic pollution, specifically nitrogen dioxide, reduced the chance that IVF would work by around 9 per cent.
