Premature, Underweight Infant Birth is the Result of Pollution Around You


NEW DELHI: As per a recent study done, air pollution can become the reason for premature and underweight birth of an infant.

The team of researchers have noticed that if the pregnant lady get exposed to pollution, this action could lead to high risk for vision as well as hearing problems, learning problems, even it can result into death. Coming in contact to air pollution in the first or second trimester in humans is associated with more negative outcomes of birth than exposure later in pregnancy.

The team of researchers studied the effects of fine particulate air pollution that basically comes from coal-fired power plants, car exhaust, and other industrial processes. They have also observed obstetric consequences associated to the exposures during different stages of pregnancy.

Lead author and investigator Jason Blum, PhD, MS, assistant professor in the Department of Environmental Medicine at NYU School of Medicine said, “This is the first study of this problem in mice adds to the growing body of signs that inhalation of particulate matter from implantation through the second trimester of pregnancy is potentially dangerous,”.

In this study, pregnant mice were casually assigned to one of two groups—one was exposed to the filtered air and the second one to the concentrated PM2.5. The mice that were exposed to particles were also assigned randomly for exposure in one of four gestational periods designed to mirror the stages of human pregnancy: period 1that is 0.5-5.5 days); period 2 that is 6.5-14.5 days; period 3 that is14.5-16.5 days; or period 4 that is 0.5-16.5 days.

The team of researchers measured both the time of pregnancy and weight during birth of the offspring for identifying the effects of concentrated PM2.5 over the time. The results they have got show that exposure to air pollution in the period one caused in preterm birth for about 83 percent of exposed mouse litters. Likewise, exposure to PM2.5 from the outset to the end of the second trimester–periods one, two and three resulted an 11.4 percent decrease in birth weight for 50 percent of the litters.

Blum said exposure to air pollution during the first and second trimester also resulted with decreased placental weight, decreased body length, and decreased anogenital distance, that can reflect abnormal hormone levels.

Senior study author Judith Zelikoff, PhD, a professor in the Department of Environmental Medicine at NYU School of Medicine stated, “These findings could lead physicians to advise women to avoid high pollution areas or use air filtration systems during the early stages of pregnancy.”

The results of this research is really shocking as there is no such place where we are free from Air Pollution.  It is important to make society pollution free no only for us, but for the upcoming generation too.
