POLLUTION CAN INCREASE RISK OF PREGNANCY COMPLICATIONS

Exposure to PM2.5 pollution can lead to higher inflammation levels potentially resulting in adverse birth outcomes

Exposure to PM2.5 pollution could lead to higher inflammation levels among pregnant women potentially resulting in adverse birth outcomes, such as low birth weight and preterm birth, according to a study examining how pollution alters human DNA.

The findings, published in the journal Science Advances, provided a new understanding of the biological routes through which air pollution affects pregnancy and birth outcomes, researchers said.

Particulate matter (PM) 2.5 pollution is caused by particles sized 2.5 micrometres or less. Common sources are vehicular and industrial emissions, while natural ones can include carbon from wildfires and dust.
