‘Fracking’ Linked to Low Birth Weight Babies
High-volume hydraulic fracturing – also known as “fracking” – allows access to large amounts of natural gas trapped in shale deposits. Natural gas wells using this method are increasingly common in the United States. For example, the number of these types of wells in Pennsylvania’s Marcellus Shale rose from 44 in 2007 to more than 2,800 in 2010, the researchers pointed out.
In this study, University of Pittsburgh researchers analyzed the birth records of more than 15,400 babies born in Pennsylvania’s Washington, Westmoreland and Butler counties between 2007 and 2010.
Women who lived close to a high number of natural gas fracking sites were 34% more likely to have babies who were “small for gestational age” than mothers who did not live close to a large number of such wells, the study found.
The findings held true even after the researchers accounted for numerous factors that could affect a newborn’s weight, including whether a mother smoked, her race, age, education, prenatal care and whether she’d had previous children, as well as the baby’s gender.
The study, published online June 3 in the journal PLOS One, does not prove that living close to a high concentration of natural gas fracking sites caused lower birth weights, but does show the need for further investigation, the researchers said.
“These findings cannot be ignored. There is a clear need for studies in larger populations with better estimates of exposure and more in-depth medical records,” study co-author Bruce Pitt, chair of the University of Pittsburgh Graduate School of Public health’s Department of Environmental and Occupational Health, said in a university news release.
“Developing fetuses are particularly sensitive to the effects of environmental pollutants. We know that fine particulate air pollution, exposure to heavy metals and benzene, and maternal stress all are associated with lower birth weight,” Pitt said.
Fracking involves pumping water and up to 50 different toxic chemicals into the ground to force the natural gas out of shale in a hydraulic process. The process extends laterally rather than straight down like a conventional well. This results in widespread contamination of the water supply for miles around these fracking sites.
The need for energy independence for the US is obvious to all but at what cost? Do we jeopardize the health of the next generation in the process? North Dakota is being decimated by fracking. The decision in that state was purely financial as they were hit particularly hard by the economic hardships over the past several years.
The Bottom Line:
We have to find a safer way to produce energy and soon. I really believe the whole planet is in jeopardy. In the end, the planet will survive, we won’t.
