Tennessee Forestfire, Gatlinburg

The great Smoky Mountains Wildfire of 2016 burned through Gatlinburg Tennessee on the evening of November 28. In assessing the smoke exposure of buildings not directly impacted by the fire there were a number of interfering effects. That included the common practice of burning leaves and branch debris in the Fall and the use of wood burning fireplaces and wood stoves during the Fall and into the Spring. Significant vehicular traffic in the local valleys added combustion particles and tire wear to the mix. These sources became more significant with the passage of time. The images here document the combustion particles found in buildings in the latter half of 2018. Debris from the Smoky Mountains Wildfire were still present but so too were the combustion particles of two years of open burning and emissions from fireplaces and woodburning stoves.
