Gas and aerosol-rich volcanic plumes can have serious impacts on human health and the environment. While the atmospheric dispersion, chemical reactions, and pollution from major components such as sulphur dioxide has been the subject of multiple studies, the trace components, such as lead, arsenic and cadmium are poorly understood. The 2018 eruption of Kīlauea’s Lower East Rift Zone provided an unprecedented opportunity for volcanologist, Dr. Evgenia Ilyinskaya and her team from the Universities of Leeds, Cambridge and Oxford, UK to collaborate with HVO, USGS and DOH to deploy both ground-based and aerial monitoring instruments for analysis. Join us for a fascinating look at what volcanic pollution really contains and the potential implications for environmental impacts.
