Research Update on Health Impacts of Dust from 9/11 Aftermath


Originally published by Erin Billups at NY1 on April 8, 2014

Last month, NY1 told viewers about another link discovered between the toxic dust many were exposed to in the aftermath of the September 11th attacks and a higher risk of heart disease, and now, the doctor heading up the research is going into more detail. NY1’s Erin Billups filed the following report.

We’ve known for years that the toxic dust inhaled by first responders to the September 11th attacks could lead to lung, heart and kidney problems, but new research out from Mount Sinai Hospital’s World Trade Center Health Program finds that those with the highest exposures are more likely to suffer from sleep apnea.

“The airway narrows during sleep, and patients snore. They hold their breath, and importantly, they don’t get enough oxygen when they’re sleeping,” says Dr. MaryAnn McLaughlin, director of the Mt. Sinai Medical Center Cardiac Health Program. “So this can cause an inflammation in the body and lead to high blood pressure, increased risks of heart attack and sudden death.”

Post-traumatic stress disorder is also a risk factor for heart disease. McLaughlin and her team found that those with high dust cloud exposure were also 20 percent more likely to have the disorder.

“It’s also associated with depression, as well,” McLaughlin says.

The findings are the result of a two-year study, surveying 800 participants.

McLaughlin says they’re trying to uncover what causes heart disease not only for those September 11th responders, but also for others placed in hazardous work conditions.

“We hope to see whether inhaling these particulates have an additive effect to worsen the risk for heart attack,” she says.

If so, McLaughlin says they may be able to find better treatments for reducing the inflammation caused by inhaling particulates.

“So if we can figure out exactly what those chemicals and hormones are that were involved, and then target therapies, those types of therapies could be generalized to other diseases as well,” she says.

The Mount Sinai researchers are still surveying a few hundred more participants toward that end.

“What’s important is that we don’t forget about the tragedy of 9/11,” McLaughlin says. “The risks can happen after years.”

She urges those that may have been exposed to continue to seek help and to consider enrolling in the Mount Sinai- or City Hospital-run World Trade Center health programs.

Since 2004, 911Truth.Org has educated the public about the suppressed realities of the September 11 attacks.

We worked with the 9/11 Families to pressure the Bush administration to convene an investigation into the deadliest attacks on US soil since Pearl Harbor. We attended many of the commission hearings and questioned commissioners and bird-dogged elected officials to get answers to the Unanswered Questions that remain so to this day.

We reported the contradictions, lies and omissions on the public record. 911Truth.Org staff have given hundreds of interviews on radio and mainstream network TV.

We cover a wide range of 9/11-related issues in publishing academic papers, original research, and opinion pieces.
