Safety Project on the Environmental Effects of Dust Suppressant Chemicals on Unpaved Roads
Research Idea Scope
TERI Administrator Note (Feb 2009) – Related Research: Investigation of Water Runoff and Leaching Impacts from Dust Suppressants, Fred Hall, US Environmental Protection Agency, 2008
The majority of research on dust suppressants has been by industry and has focused on the effectiveness (or performance) of dust suppressants to abate dust, however, little information is available on the potential environmental and health impacts of these compounds.
The project will consist of two parts – laboratory testing and field assessment.
The laboratory project will evaluate the toxicity of two chemical classes of dust suppressants 1) in laboratory tests with aquatic and terrestrial organisms as well as aquatic and terrestrial plants and 2) in field studies to determine effects of these chemicals on biological communities in natural areas following chemical application. The results will be compared among chemical classes and the potential environmental effects will be identified and ranked using a risk assessment framework.
Urgency and Payoff
The purpose of the project is to assure that dust suppressants are used and applied in a manner that will protect the animal, plant and aquatic systems while providing significant reductions in dust particulate matter for cleaner air and safer driving conditions on unpaved, public gravel roads.
