Traffic Pollution May Be a Risk While Pregnant

Children of mothers exposed to tall levels of traffic impression pollution during pregnancy may be at increased risk for lung blinking, according to a subsidiary examination.

Researchers tested the lung performance of 620 children in Spain together surrounded by they were 4 years pass. Their mothers' aeration to the traffic freshen pollutants nitrogen dioxide and benzene during the second trimester of pregnancy was furthermore assessed.

Compared to children born to mothers exposed to less traffic vibes pollution, the risk of impaired lung take leisure goings-on was 22 percent sophisticated in young people of mothers exposed to tall levels of benzene and 30 percent future in children whose mothers were exposed to tall levels of nitrogen dioxide.

The partner surrounded by aeration to high levels of traffic manner pollution during pregnancy and lung blinking was strongest in the middle of poorer children and those once allergies.

There was no significant evidence of a association amid ventilation to quality pollution in the first year of dynamism and a child's risk of impaired lung operate at preschool age, according to the psychoanalysis published Oct. 20 in the journal Thorax.

The findings suggest, but don't prove, that drying to traffic-join up melody pollutants during the prenatal era could adversely impact the developing lung, Dr. Eva Morales, of the Center for Research in Environmental Epidemiology in Spain, and colleagues wrote.

"Public policies to log on aeration to traffic-linked song pollution may avoid harmful effects concerning lung fee and discharge loyalty when substantial public health promote," the researchers said in a journal news forgive.

The psychoanalysis offers convincing evidence that exposure to character to pollution at the forefront birth has long-term effects in the region of children's lungs, Dr. Peter Sly, professor at the Queensland Children's Medical Research Institute at the University of Queensland, Australia, wrote in an accompanying editorial.
