Exposure to air pollution is linked to babies' growth during pregnancy, according to a landmark new study.

Scientists at the University of Aberdeen have reviewed over a decade's worth of research evidence from around the world to establish the extent to which mothers' exposures to air pollution, diet, alcohol and chemicals affects fetal growth.

Evidence - Alcohol - Chemicals - Factors - Study

While there was insufficient evidence that poor diet, alcohol or chemicals were factors, the study found evidence that exposure to nitrogen dioxide resulted in smaller fetal head size, particularly in the last three months of pregnancy.

Nitrogen dioxide is primarily generated by vehicle traffic, but can be present in the home from cigarette smoke, or butane and kerosene heaters and stoves.

Professor Steve Turner, who led the study, said: "In our research we looked at all the studies that measured the effects of mothers' exposures to everyday substances including air pollutants, alcohol, and diet on the size of the unborn baby, measured through ultrasound from half way through the pregnancy onwards.

"What was unique about our review of the literature is that...
