The study, which was led by a team from The Stockholm Environment Institute (SEI) at the University of York, found that in 2010, about 2.7 million preterm births globally -- or 18 per cent of all preterm births -- were associated with outdoor exposure to fine particulate matter (PM2.5). In 2010, an estimated 14.9 million births were preterm -- about 4-5 per cent of the total in some European countries, but up to 15-18 per cent in some African and South Asian countries. A new study published in the journal Environment International for the first time quantifies the global impact by combining data about air pollution in different countries with knowledge about how exposure to different levels of air pollution is associated with preterm birth rates. The largest contribution to global PM2.5-associated preterm births was from South Asia and East Asia, which together contributed about 75 per cent of the global total. "There is uncertainty in these estimates because the concentration-response function we used is based mainly on studies in the United States and Europe," Malley said.
We need to be aware now a days that the actions that we are doing have consequences. One example is the air we breathe in and the pollutants that we are putting into our air. We need to be aware of the chemicals that we are putting into the air. Some of the chemicals that we are putting into our air can cause cancer and birth defects like stated above. In order to stop the pollution of air, we need to take action fast and start thinking about what we are putting into our, so we can save the future of future generations.
