Telomeres of chromosomes Particles Length of lifespan
The telomeres of chromosomes are called the "life clock" and the faster they shorten, the shorter the lifespan!
Telomere length is the most reliable biological marker for measuring aging and predicting life expectancy.
Harm of particles to telomeres
Accelerate telomere depletion by causing oxidative stress and inflammatory responses
For every 5μg/m3 increase in the annual average PM2.5 concentration, there is a relative decrease in telomere length of 16.8%.
The reduction in initial telomere length in newborns predicts an increased risk of various chronic diseases later in life.
