Airborne Contaminants

SEAN's long-term Airborne contaminants monitoring program is still under development. It is intended to fulfill these objectives:

  • Determine concentrations and decadal trends of airborne contaminants as manifested in concentrations in lichen tissue, and determine how contaminant concentrations in lichen tissue relate to ambient air concentrations and rates of deposition.
  • Determine whether lichen communities are changing over time in response to changes in air quality.
  • Determine Hg wet deposition amounts and temporal patterns and compare these rates with other sites in Alaska to assess temporal and spatial variation in Hg deposition rates across Alaska sites.
  • Develop a protocol (following Oakley et al 2003) for long-term monitoring of air quality trends with lichens as 1) air quality sensors for elemental analysis in conjunction with passive chemical sensors and deposition samplers and 2) bioindicators as expressed through community monitoring plots for the SEAN I&M program.

No airborne contaminants monitoring data are currently available.
