Air pollution impacts every community. Research shows prenatal exposure to polluted air can alter DNA methylation, creating long-term health risks across generations
Studies have revealed significant public health implications of prenatal exposure to air pollution. Research indicates that such exposure can alter DNA methylation in newborns (Baccarelli et al., 2020). This crucial finding underscores the enduring impacts of environmental factors on epigenetic processes, with the potential to affect health outcomes across generations.
Dr. Andrea Baccarelli, an Epigeneticist and clinical Endocrinologist at Columbia University, elaborated on the long-term effects, stating, “We are finding that environmental exposures can leave an imprint on our DNA that may persist for generations.”
The National Institutes of Health (NIH) reported in 2022 that exposure to fine particulate matter is associated with altered gene expression related to inflammation. This discovery highlights how environmental pollutants, such as those from vehicle exhaust and industrial emissions, can trigger biological responses that lead to inflammation, contributing to various health issues.

Thick smoke rises from coal plant stacks, a stark reminder of how industrial emissions contribute to polluted air. Studies link this exposure to DNA changes in newborns, influencing health outcomes far beyond the present.

Furthermore, research has shown that epigenetic changes linked to pollution can persist across multiple generations, suggesting that exposure to environmental toxins not only affects individuals in the present but can also have lasting consequences for their offspring (Braun et al., 2021). Dr. Joseph Braun, Professor of Epidemiology at Brown University, emphasized this point by saying, “Pollution doesn’t just make people sick now, it can alter the biology of their children and grandchildren.”

These findings underscore the urgency of addressing air pollution as a critical public health issue, with long-term epigenetic impacts influencing future generations. The studies emphasize the importance of implementing effective policies and measures to reduce exposure to air pollution and protect public health.
In summary, prenatal exposure to air pollution can lead to DNA methylation changes in newborns, while fine particulate matter exposure is associated with altered gene expression and inflammation. These epigenetic changes can have lasting effects across generations, highlighting the critical need for proactive measures to mitigate pollution levels and safeguard public health.
