Sensitive instruments to track methane, VOCs and other airborne toxins from New Mexico to North Dakota

FRISCO — A recent study of satellite data showing a hotspot of potent heat-trapping methane pollution over the Four Corners region makes it clear that we’re digging an ever-deeper global warming hole by fracking every last corner of the country.
As NOAA put it, “Vast regions west of the Mississippi River are under development for oil and gas extraction … but while one focus is on what comes out of the ground, NOAA and Cooperative Institute for Research in Environmental Sciences researchers and their colleagues are studying what escapes to the air—and how it is transformed in the atmosphere and affects air quality and climate.
Scientists hope to learn much more about the massive quantities of pollution escaping from fossil fuel development areas in the next few months as they launch this year’s Shale Oil and Natural Gas Nexus (SONGNEX 2015) field campaign, using airborne instruments to measure greenhouse gases and other toxic emissions.

If you use scented laundry products, your dryer may be a source of carcinogenic compounds.
SUMMIT COUNTY — Unregulated chemicals in laundry products emit more than 20 volatile organic compounds when they’re used in household dryers. The compounds include seven hazardous air pollutants and two known carcinogens — acetaldehyde and benzene — for which the EPA has not established safe exposure levels.
The University of Washington research suggests that, based on the amount of laundry products used in the region, household clothes dryers could account for the equivalent of 6 percent of the amount of acetaldehyde emissions coming from automobiles.
The study was done by Anne Steinemann, a UW professor of civil and environmental engineering and of public affairs. Steineman previously used chemical sleuthing to deduce what chemicals are being used in fragranced consumer products.
Steinemann says she was spurred to do the study by people reporting adverse reactions to fragranced air coming from laundry vents. The project’s website includes letters from the public reporting health effects from scented consumer products.
“This is an interesting source of pollution because emissions from dryer vents are essentially unregulated and unmonitored,” Steinemann said. “If they’re coming out of a smokestack or tail pipe, they’re regulated, but if they’re coming out of a dryer vent, they’re not.” Continue reading
