Plastic that grows on trees

...benefit: It is reusable, thus produces none of the wastewater in other methods that convert fructose to HMF. Metal chlorides belong to a class of ionic-liquid-soluble materials called halides, which “in general work well for converting fructose to HMF,” Zhang said — but not so well when glucose is the initia...

Leeches ferry infection among newts

... The Penn State researchers say fertilizer-laden wastewater from farms and other sources often causes increased growth of aquatic vegetation in ponds, providing leeches with a firmer footing. "It could lead to more leeches and create potential hotspots of disease," Raffel noted....

Earth Rx: A microbial biotechnology prescription for global environmental health

..., first adapted widely in the 1910s and 1920s when wastewater was cleaned up by a bacterial-laden sludge that speeds up the breakdown of the organic material in sewage. With recent advances in biology, materials, computing, and engineering, environmental biotechnologists now are able to use microbial communit...

UCR environmental scientists propose chemical solution to cleaning California's Salton Sea

GROWing the next generation of water recycling plants

...e used twice before being placed into the national wastewater management system. "We had to carefully choose which semi-aquatic plants to use. One of the most successful is water mint, whose roots have disinfectant qualities," says Professor David Butler, who oversees the project at Imperial College. The other...

Toxic flood lifts lid on common urban pollution problem

...s "greater than those found in untreated municipal wastewater from the same service area," according to the study. The findings were based on periodic analysis of runoff that drains off Interstate 10 into Baton Rouge's City Park Lake just below the highway. Based on data first gathered in 1999, they revealed h...

Transgenic plants remove more selenium from polluted soil than wild plants, new tests show

...ed canal originally intended to channel irrigation wastewater from Central Valley farms to the Sacramento River Delta near Antioch. Selenium is considered an essential trace mineral for both humans and animals, but it becomes toxic at high doses. The dangers of selenium toxicity came to light in the 1980s when ...
