Leaded aviation fuel a threat to public health, children

KUOW’s John Ryan used federal data and a few key sources to delve deep into issues surrounding one of the few remaining sources of airborne lead in the United States, a leaded aviation fuel known as “avgas.” In the process, he reveals damage that even low levels of lead exposure could be doing to children.

Avgas accounts for less than 1 percent of the nation’s liquid fuel use. Yet enough piston–engine planes fly enough miles on avgas to belch out half of all the lead going into the nation’s air.

Lead paint in old buildings remains a bigger threat, but even low levels of childhood exposure, one source tells Ryan, can manifest itself in “Decreases in IQ, changes in test scores, changes in attention, hearing threshold, all sorts of things like that.”

Earlier this month (January), an expert panel advising the Centers for Disease Control and Prevention cut in half the levels of lead in children that should alarm parents or doctors. Researchers have yet to find any level of lead exposure that doesn’t cause harm.

Michael Kosnett, a medical toxicologist at the University of Colorado, told Ryan, “In any one child, it’s not something that’s going to necessarily cause them to display any kind of signs and symptoms. But if you can lower the lead exposure of a population of children, you’re going to give that population more of an opportunity to have gifted children and to have children who have higher IQs, and that’s certainly a desirable public health goal.”

Marie Lynn Miranda, an environmental health scientist and a dean at the University of Michigan, points out that “Living close to an airport can increase your blood lead level anywhere from 2 to 4 percent,” acknowledging that is a small amount but that evidence indicates even small amounts of lead are bad. She also notes that “lead is especially a problem for the low–income families that are most likely to live near airports.”

Pilots who still use avgas say their businesses would be dead in the water if they couldn’t get the leaded fuel, an argument Ryan contrasts with quotes from a Europe-based lead-free avgas producer, who sells it for 40 cents less a gallon, but hasn’t been able to break into the U.S. market “Because no one thinks that there will be demand for an unleaded–grade aviation gasoline.”

The federal database Ryan used, The National Emissions Inventory, is posted online by the EPA.

Investigation delves into Wash.’s prescription drug problem

Everything time we think prescription drug abuse stories have peaked, something comes along to push the story further. This time, InvestigateWest’s Carol Smith sets herself apart by starting from square one and clearly explaining the origins and dimensions of Washington’s particularly nasty drug issues, tracing back each facet of the problem to its source and spotlighting what makes the Evergreen State unique.prescription-drugs

Washington has been one of the hardest hit states in the country, in part because of aggressive prescribing practices. That, coupled with lack of oversight of doctors who over-prescribe, has led to the spectacular run-up in the number of deaths from prescription overdoses.

The backdrop for her work is an epidemic that shows no signs of abating, despite a recently implemented state law Smith calls “a bold attempt to reduce overdose deaths by launching the first-ever dosing limits for doctors and others who prescribe these medicines.”

Prescription drug abuse is at epidemic levels throughout the state, and elsewhere in the country, despite lawmakers’ attempts to get a grip on it. Washington now has one of the highest death rates in the nation. Deaths from prescription drug overdoses in this state have skyrocketed nearly twenty-fold since the mid-1990s, and now outstrip those from traffic accidents.

Why caused it to leap so quickly? Smith tracks down several key tipping points. “There’s plenty of blame to go around for what caused the epidemic,” she writes. “Aggressive marketing of opiates by drug companies, nonexistent tracking of overprescribing, lack of insurance coverage for alternative treatments for pain, and demand by patients for quick fixes, to name a few.”

She drills down into many of those causes, with my personal favorites being two key origin stories:

  • How marketing by OxyContin maker Purdue Pharma led to relaxed guidelines for chronic pain treatment and a “1999 law specified ‘No disciplinary action will be taken against a practitioner based solely on the quantity and/or frequency of opiates prescribed,'” both of which helped cause a jump in prescriptions.
  • How “the rise in the death rates of Medicaid patients tracks along with the state’s cost-saving decision to move many of its poorest residents to the cheapest, most potent pain reliever available: Methadone.”

Seattle hospitals love building costly ERs

The Puget Sound emergency room construction boom is in full swing, and Seattle Times reporter Carol Ostrom has taken a pointed look at the cost-related consequences of local hospital expansion.

She examines why hospitals are opting for more and glitzier ERs over lower-cost alternatives such as clinics and urgent care facilities. She also considers why state efforts to guide hospitals toward more efficient spending have failed, and explains how hospitals justify their actions. If you don’t have time for the full story, here’s a relatively tame excerpt:

The ER building boom has prompted a backlash from some lawmakers and advocates of affordable health care, who complain that nearly all Washington hospitals get substantial tax breaks and construction financing through tax-exempt bonds.

Free-standing ERs, these critics charge, are cash cows for hospitals, strategically built in affluent areas to lure busy, well-insured patients and collect fat reimbursements.

Blame trucks, not just factories, for industrial pollution in Seattle

Spurred by a few recent studies, InvestigateWest’s Robert McClure and KCTS-Seattle’s Jenny Cunningham launched an investigation to figure out just what has made Puget Sound’s air some of the most toxic in the nation. Their work centered on the heavily polluted, industrial Seattle neighborhoods of Georgetown and South Park, where residents “face an onslaught of toxic airborne pollutants that according to a recent study exceed regulatory caution levels by up to 30 times.”

Where is this toxic air coming from? The answer may surprise you. The majority of the pollution, government regulators and scientists say, comes not from the large concentration of industrial facilities in South Park and Georgetown. Rather, it’s from the cars, trucks and buses whizzing by these neighborhoods – especially those with diesel engines. Fumes from ships in Elliott Bay and the Duwamish, as well as diesel-powered equipment at the Port of Seattle and elsewhere, add to the toxic mix. In the fall and winter, wood smoke from fireplaces becomes a significant contributor.

The problems here have implications in other neighborhoods, too: Anywhere people are living close to major roadways, they’re likely breathing unhealthy air, studies show. Anyone living within about 200 yards of a major roadway is thought to be at increased risk, with the first 100 yards being the hottest pollution zone.

Reporters looking to localize the story will probably want to scroll first to the “The Effects” section, which gets into the practical science of how this sort of pollution takes its toll. You’ll probably also enjoy Cunningham’s sidebar on what she learned in reporting the piece (it’s at the bottom of the page). If you’re also looking to understand the regional and national regulatory structure which governs diesel and related emissions, the “Solutions” subheading is also worth a pit stop.

Should Seattle Superfund site address health as well as pollution?

InvestigateWest’s Carol Smith writes in the Seattle Post-Intelligencer and InvestigateWest.org that the focus on the environmental disaster of Seattle’s industrial Duwamish River obscures another, equally potent, long-simmering health crisis. For the folks who live near the Superfund site, pollutants from the river are just one of many health risks. Access to groceries and health care is limited, and obesity and poverty rates are higher than surrounding neighborhoods while expected lifespans are years shorter. As Superfund recommendations begin to take shape, the health side of the cleanup is bubbling to the forefront.

While there’s been exhaustive analysis of the environmental impact of historical polluters on the river and the health of creatures that live in it, as well as theoretical risk assessments of individual pollutants on human health, relatively little attention has been paid to the actual health status of residents living within the 32-square-mile Superfund site. Nor has there been consideration of the cumulative impact of the many health hazards they face.

The big question, Smith writes, is “Should the area be held to a higher cleanup threshold because the people living in its midst are already more vulnerable to the health risks posed by the toxic chemicals in their environment? ”

The answer might lie in the area’s status as an “environmental justice neighborhood,” which means it is “subject to the 1994 executive order by President Clinton that directed federal agencies to address inequities in communities where low-income or minority communities were experiencing health disparities caused by their environment.”
