Air Pollution Tied to Increased Risk of Miscarriages

A study has linked exposure to three air pollutants—fine particulate matter, sulfur dioxide, and nitrogen dioxide—to an increased risk of miscarriage during the first trimester of pregnancy. Conducted in Baoji, China, the research analyzed data from 770 pregnant women and found higher miscarriage rates during seasons with poorer air quality. The pollutants, primarily from fossil fuel combustion, are prevalent in urban areas and may disrupt pregnancy hormones or cause inflammation. While the study highlights a significant correlation, it does not establish causation, and further research is needed.
