What’s That On the Side of Jakolof Bay Road?
by Ian McGaughey

The unusual looking devices are high-volume air samplers, which stand next to gray cases on tripods housing DustTrak II aerosol monitors. Both units collect information about levels of road dust in the air, otherwise known as PM10, which is particulate matter with a diameter of 10 micrometers or less. SVT has installed two of these systems along Jakolof bay Road.

SVT’s environmental staff will be monitoring the road dust levels from June through the end of September. The high volume samplers are on loan to SVT from the Alaska Department of Environmental Conservation and the aerosol monitors are from the Alaska Native Tribal Health Consortium. For more information, please contact Environmental Coordinator Michael Opheim at (907) 435-3247 or mopheim@svt.org or Tracie Merrill (907) 435-3261 or tmerrill@svt.org.
