BGU researchers develop sensor to detect nanoplastics in the air using carbon dots

Green Car Congress

Large pieces of plastic can break down into nanosized particles that often find their way into the soil and water. It’s unclear how nanoplastics impact human health, but animal studies suggest they’re potentially harmful. Animal studies suggest that ingesting and inhaling these nanoparticles may have damaging effects.

Graphene Flagship team develops powerful graphene-titania photocatalyst to reduce NOx

Green Car Congress

By performing liquid-phase exfoliation of graphite—a process that creates graphene—in the presence of titania nanoparticles, using only water and atmospheric pressure, they created a new graphene-titania nanocomposite that can be coated on the surface of materials to passively remove pollutants from the air.

Nielsen global survey finds concerns about climate change slipping behind concerns over other environmental issues; air and water pollution top worries, pesticide use #3

Green Car Congress

Three out of four global consumers rated air pollution (77%) and water pollution (75%) as top concerns, both increasing six percentage points compared to 2009. The study found that there are a number of consumers who are either indifferent or not concerned about this issue.
