Measuring Precipitation, One Drop at Time

Rain is never appreciated during a picnic and fog is aggravating to motorists, but those small droplets of water may actually hold the key on a small scale what is happening, or could happen, on a much larger scale. While oceans, lakes, rivers or rain are overt examples of how water supports all [...]

Hsu-Kim Receives DOE Award

Heileen Hsu-Kim believes that before scientists can solve the big-picture issue of protecting people and the environment from the harmful effects of mercury, they need to see the small picture. The very small picture. She would like to like know exactly what happens when naturally-occurring or man [...]

CEINT Adds New International Nano-Safety Initiative

The cleanliness of our water faces pressures from many directions. More factories mean more discharges, a growing population leads to more wastewater, and more runoff from lawns and farms carries pollutants into waterways. While there are many elements in water that may be harmful to people and the [...]

Why Mercury is More Dangerous in Oceans

DURHAM, N.C. -- Even though freshwater concentrations of mercury are far greater than those found in seawater, it's the saltwater fish like tuna, mackerel and shark that end up posing a more serious health threat to humans who eat them. The answer, according to Duke University researchers, is in [...]

When Nano May Not Be Nano

DURHAM, N.C. -- The same properties of nanoparticles that make them so appealing to manufacturers may also have negative effects on the environment and human health. However, little is known which particles may be harmful. Part of the problem is determining exactly what a nanoparticle is. A new [...]

How Mercury Becomes Toxic in the Environment

DURHAM, N.C. – Naturally occurring organic matter in water and sediment appears to play a key role in helping microbes convert tiny particles of mercury in the environment into a form that is dangerous to most living creatures. This finding is important, say Duke University environmental engineers [...]
