The American Lung Society reports that
one in three people in the U.S. lives in counties
with unhealthy air pollution levels.
Particulate matter contains microscopic
solid and liquid droplets that are so small
that they can be inhaled into the deepest
part of the lungs, enter the bloodstream
and reach many downstream target
organs, including the ovaries
and other reproductive organs, Robert Hood, postdoctoral trainee fellow at Emory
University's Rollins School of Public Health, via 'Newsweek'.

According to a study published in the journal 'Environmental
Health Perspectives,' exposure to air pollution
may impact the age at which girls enter puberty.
We think that particulate matter may
primarily affect puberty onset 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, postdoctoral trainee fellow at Emory
University's Rollins School of Public Health, via 'Newsweek'.
Another related pathway is through
increasing the risk for childhood obesity,
which is one of the best-characterized
risk factors for earlier puberty onset in girls, Robert Hood, postdoctoral trainee fellow at Emory
University's Rollins School of Public Health, via 'Newsweek'.
Experts warn that early-onset puberty has been linked with hormone-related cancers, cardiovascular disease, hypertension
and metabolic syndrome, 'Newsweek' reports.

Early-onset puberty has also been associated
with wide-ranging impacts on the reproductive
system, including earlier menopause
