Latest Environmental implications of nanotechnology Stories
Sunscreens, lotions, and cosmetics contain tiny metal nanoparticles that wash down the drain at the end of the day, or are discharged after manufacturing.
Engineered nanomaterials, prized for their unique semiconducting properties, are already prevalent in everyday consumer products — from sunscreens, cosmetics and paints to textiles and solar batteries — and economic forecasters are predicting the industry will grow into $1 trillion business in the next few years.
With the curtain about to rise on a much-anticipated new era of "nanoagriculture" — using nanotechnology to boost the productivity of plants for food, fuel, and other uses — scientists are describing huge gaps in knowledge about the effects of nanoparticles on corn, tomatoes, rice and other food crops.
Nanotechnology refers to a broad range of tools, techniques and applications that simply involve particles on the approximate size scale of a few to hundreds of nanometers in diameter.
As researchers around the world hasten to employ nanotechnology to improve production methods for applications that range from manufacturing materials to creating new pharmaceutical drugs, a separate but equally compelling challenge exists.
The same properties of nanoparticles that make them so appealing to manufacturers may also have negative effects on the environment and human health.
