A portable particle detector can determine aerosol concentrations in public spaces — ScienceDaily

Because of the role they play in coronavirus transmission, understanding aerosol concentrations and persistence in public spaces can help determine infection risks. However, measuring these concentrations is difficult, requiring specialized personnel and equipment. That is, until now. Researchers from the Cardiology Centers of the Netherlands and the University of Amsterdam demonstrate that a commercial hand-held […]

New research reveals widespread contamination, with two neurotoxic pesticides found in concentrations that far exceed accepted safe limits — ScienceDaily

Researchers at the University of Sussex have found widespread contamination of English rivers with two neurotoxic pesticides commonly used in veterinary flea products: fipronil and the neonicotinoid imidacloprid. The concentrations found often far exceeded accepted safe limits. These chemicals are banned for agricultural use due to the adverse environmental effects, but there is minimal environmental […]
