According to WHO estimates, exposure to fine particles causes 7 million deaths each year worldwide. The American Lung Society reports that one in three people in the United States lives in an area where pollution is harmful to their health.
“Particulate matter contains microscopic liquid and solid droplets that are so small that they can be inhaled to the deepest part of the lungs, enter the bloodstream and reach organs like the ovaries or other reproductive organs” says Robert Hood, a postdoctoral fellow at Emory University’s Rollins School of Public Health.
According to a study published in the journal Environmental Health Perspectives, exposure to pollution might impact the age at which girls reach puberty. “We believe that particulate matter can affect the arrival of puberty by disrupting the endocrine system or more specifically the hypothalamic-pituitary-ovarian axis which is the key regulator of hormones and reproductive development,” Robert Hood emphasized. .
Childhood obesity is also increased by exposure to fine particles and is one of the factors that can cause premature puberty in girls, the study explains. Experts warn that premature puberty is linked to hormone-driven cancers, cardiovascular disease, hypertension and metabolic syndrome, says Newsweek. It is also associated with a wide range of disruptions to the reproductive system, including premature menopause.
