For the particle test, the government plans to release titanium dioxide, which it describes as a “white odorless powder that is chemically insoluble in water, nonreactive, nonflammable and nonhazardous.”
For the biological test, the government plans to release genetic, barcoded spores of an insecticide sold under the trade name of Dipel. Dipel is not considered hazardous by the Environmental Protection Agency when handled appropriately, according to an assessment.
The assessment said the test will have no adverse impact on human health or the environment.
