Researchers at the University of Colorado studied pregnant women who are among the 17 million Americans living within a mile from an active oil or gas well
Proximity to oil and gas sites makes pregnant mothers up to 70 percent more likely to give birth to a baby with congenital heart defects, according to a new study.
Led by Dr. Lisa McKenzie at the University of Colorado, researchers found that the chemicals released from oil and gas wells can have serious and potentially fatal effects on babies born to mothers who live within a mile of an active well site—as about 17 million Americans do.
The researchers studied more than 3,000 newborns who were born in Colorado between 2005 and 2011. The state is home to about 60,000 fracking sites, according to the grassroots group Colorado Rising. In areas with the highest intensity of oil and gas extraction activity, mothers were 40 to 70 percent more likely to give birth to babies with congenital heart defects (CHDs).
“We observed more children were being born with a congenital heart defect in areas with the highest intensity of oil and gas well activity,” said McKenzie in a statement.
The study was more precise than previous reports about the link between oil and gas extraction and CHDs. The researchers studied families in which the pregnant mother lived near an active oil or gas well up to the second month of pregnancy, when fetal cardiac development takes place.
They also estimated the level of intensity of the oil and gas activity, determined exactly how close the pregnant mothers lived to the well sites, and ensured there were no other significant air pollution sources which could skew their results.
One science journalist, on social media, called the study “extremely convincing.”
This study that found a 40-70% increased risk of congenital heart defects in children born close to oil and gas infrastructure is extremely convincing. They adjusted for all the things I wondered about when I first saw the headlines.https://t.co/Unccpzi9MD

Biologist Sandra Steingraber was among the experts on the dangers of fossil fuel extraction who pointed to the study as the latest evidence that allowing oil and gas wells to operate, especially near communities, is a public health hazard.
“It’s a strong study,” Steingraber wrote on Twitter after reading the paper, noting that the researchers built on knowledge scientists already have about chemicals that are known to be harmful to prenatal health and that are released during fracking.
2/ First of all, the link makes sense. We know that these specific birth defects, which affect the valves and great arteries of the heart, are associated w prenatal exposure to benzene/diesel exhaust, and we know that benzene/diesel exhaust are found in air near fracking sites.

Previous studies about the effects of oil and gas drilling on cardiac health of newborns “did not take into account stage of pregnancy or what was happening at the wellpad during that window of time,” wrote Steingraber. “This matters because the cardiac structures form very early in development—during the first two months. If fracking is literally wrecking the hearts of unborn babies it has to do so in early pregnancy.”
“Looking at where mothers lived immediately before pregnancy and during the first critical weeks after conception and what was going on at nearby fracking wells, researchers found startling patterns,” she added.
CHDs are the leading cause of death in infants who have birth defects. Babies born with CHDs are more likely to show a “failure to thrive,” experience brain injury, and exhibit developmental challenges.
The study comes as President Donald Trump plans to open up 725,000 acres of public land in California to oil and gas companies. The president has offered a total of 378 million acres of public land and water for oil and gas drilling activities since taking office.
Steingraber called on opponents of fossil fuel extraction to speak out about their opposition by appealing to lawmakers and in letters to the editor, noting that McKenzie has been targeted by oil and gas giants for years as they fight research revealing the public health dangers they pose.
8/ Lead author Lisa McKenzie at the CU School of Public Health is a longtime target of the oil and gas industry, which has been trying to discredit her for years, so this is surely a let-the-games-begin moment for her. Letters to editors across the land would be welcome. FIN

Historians demolish John Yoo for claim Founding Fathers wouldn’t want Trump impeached in an election year
Comments made by attorney and law professor John Yoo on Fox News on the Founding Father's intentions about impeachment received a brutal debunking by two historians -- including one of his colleagues at UC Berkeley.
Appearing with Fox News personality Laura Ingraham, lawyer Yoo -- who is infamous for providing President George W. Bush's administration with legal justifications for the torture of prisoners of war -- claimed that the Founding Fathers would object to the president being impeached in an election year.
According to Yoo, Democrats are getting it all wrong when they say the Constitution compels them to hold impeachment proceedings against Trump just one year before the election.
McConnell drops a surprise on Trump — calls for an even stronger resolution to rebuke him
Senate Majority Leader Mitch McConnell (R-KY) indicated he opposes the bill out of the House to denounce President Donald Trump's military withdrawal in Syria because it isn't tough enough, reported Bloomberg's Steven Dennis.
"My first preference is for something stronger than the House resolution," McConnell said according to Bloomberg's Laura Litvan.
She went on to say that McConnel wants a bill that outlines what action should take place in Syria.
McConnell said the House version was "curiously silent on the issue of whether to actually to sustain a U.S. military presence in Syria."
Pelosi asks America to pray for Trump’s health after president suffers a ‘very serious meltdown’
President Donald Trump's Twitter attack on House Speaker Nancy Pelosi following an acrimonious White House meeting appears to have backfired spectacularly.
Trump tweeted a picture of the encounter Wednesday showing a standing Pelosi pointing at the president while he and everyone else in the room was seated, with the caption "Nervous Nancy's unhinged meltdown!"
However, far from being upset at the picture, Pelosi posted it as her Twitter banner, and her supporters said it showed her literally standing up to Trump.
"Can a woman beat Donald Trump? Yes. Speaker Pelosi does it every day," Democratic Senator Amy Klobuchar said as she retweeted the picture.
