air quality
kkrisberg | July 1, 2016Dr. Jodi Sherman wants to expand the medical profession’s understanding of patient safety far beyond the exam room and hospital bed. For Sherman, the oft-heard medical mantra of “first do no harm” should also push the health care system to do more to reduce its harmful air emissions and their impact on people’s health.
“Traditionally, our duty has been to the patient in front of us,” Sherman told me. “But we have a duty to protect society as well.”
Sherman, an assistant professor of anesthesiology at Yale School of Medicine, recently co-authored a new study on harmful air pollutants coming…
kkrisberg | April 4, 2016In debates over air pollution control, it’s always a tug-of-war between the cost to business and the cost to public health. Late last month, a study emerged with new data for the public health column: the cost of the nation’s nearly 16,000 annual preterm births linked to air pollution is more than a whopping $5 billion.
Published in Environmental Health Perspectives, the study estimated the burden of U.S. preterm births and related costs associated with fine particulate matter (PM2.5) — a pollutant from motor vehicles and the burning of fuels such as wood and coal. While preterm birth is a…
kkrisberg | January 28, 2016Each year, the U.S. spends $26.2 billion on costs associated with preterm birth — that’s birth before 37 weeks of pregnancy. Beyond the costs, babies born too early experience immediate and long-term problems, from developmental disabilities to asthma to hearing loss. For years, scientists have been studying possible environmental contributors, with many finding an association between preterm birth and air pollution. Earlier this week, a new study brought even more depth and clarity to this connection.
Published in the journal Environmental Health, the study found that exposure to high levels…
kkrisberg | December 17, 2014When compared with gasoline-powered cars, vehicles fueled with electricity from renewable sources could cut air pollution-related deaths by 70 percent, according to a new study, which noted that air pollution is the country’s greatest environmental health threat.
Published this week in the Proceedings of the National Academy of Sciences, the study’s researchers examined the impact of various vehicle energy sources on the concentrations of two types of air pollutants known to affect human health: particulate matter and ground-level ozone. Previous research has found that air pollution causes…
kkrisberg | October 31, 2014A recent study of air quality around unconventional oil and gas extraction sites — more commonly referred to as fracking — found high levels of benzene, hydrogen sulfide and formaldehyde, all of which pose risks to human health. But what makes this study particularly interesting is that the air samples were collected by the very people who live near the extraction sites, and the collection times were specifically triggered by the onset of health symptoms.
Published yesterday in the journal Environmental Health, the study involved residents living near 11 unconventional extraction sites in…
kkrisberg | August 6, 2014Next time you pass a tree, you might want to give it a second thought. Maybe even a hug. One day, that tree might just help save your life.
Let me explain. In a new study published in the Environmental Pollution journal, researchers found that the positive impact that trees have on air quality translates to the prevention of more than 850 deaths each year as well as 670,000 incidences of acute respiratory symptoms. In 2010 alone, the study found that trees and forests in the contiguous United States removed 17.4 million metric tons of air pollution, which had an effect on human health valued…
kkrisberg | July 3, 2014Crystalline silica, hydrofluoric acid and formaldehyde. Those are just three of the dozens of air toxic chemicals that oil companies have used thousands of times in southern California in just the past year.
The data has come to light thanks to new reporting rules adopted in 2013 by the South Coast Air Quality Management District, which now requires oil and gas well operators to disclose the chemicals they use in oil and gas operations. According to a recently released analysis of the first year’s worth of reported data, oil companies used 44 different air toxic chemicals more than 5,000…
lborkowski | September 12, 2011As Jori Lewis notes in the case study about World Trade Center recovery workers' health and safety, those who showed up at Ground Zero on the days and weeks after 9/11 got some misleading information about the risks they faced. Most notably, the EPA issued reassuring statements about the air quality - when, according to a 2003 EPA Inspector General report, the agency had insufficient data and analyses to support calling the air there safe. More accurate information might have increased the use of respirators and delayed people's return to homes and offices in the vicinity of Ground Zero. Now…
sastyk | July 21, 2011As most of the country slowly roasts in one of the worst heat waves so far, I thought it was worth reminding people that one can stay safe in the heat, even without air conditioning. This is important now for the millions of people who don't own air conditioners, who don't want the environmental impact of an air conditioner, or who find themselves for various reasons, without power in the hot weather. As we all know, this is peak season for brown and blackouts.
There are a lot of parallels between dealing with extreme heat and extreme cold in a difficult situation. The first and most…
sastyk | July 5, 2010The northeast is having its first heatwave of the year, and I thought it was a good time to re-run a piece I wrote about what to do in extreme heat if you don't have air conditioning. Because we all know what heatwaves mean - not just physical stress, health crises and unnecessary deaths from heat, but also blackouts and brownouts as everyone charges up their a/c. So what do you do when the power is out and the heat is on? These suggestions include, I think, the most important strategy - be aware of other people.
There are a lot of parallels between dealing with extreme heat and extreme…
