Key points from article :
Telomeres are short stretches of DNA are the ends of chromosomes and are essential for fidelity of genetic information during cell division.
Telomere length (TL) has been associated with cellular longevity and is thought to play an important role in cellular aging and senescence.
Many exposures, including pollution, may have an effect on TL.
The current study found that prenatal environmental pollution exposure was linked to decreased telomere length measured in cord blood and placental cells.
The study was published in the JAMA Pediatrics journal.
