Removing toxic mercury from contaminated water

Water contaminated with mercury and other toxic heavy metals is a major cause of environmental damage and health problems worldwide. Now, researchers from Chalmers University of Technology, Sweden, present a totally new way ...

Genetically engineered yeast soak up heavy metal pollution

Environmental contamination with heavy metals is often the result of various types of industrial processes. Because heavy metals can be dangerous to humans and other wildlife, contaminated sites need to be cleaned up. This ...

Herbal defluoridation of drinking water

Researchers in India have developed a filter system based on a medicinal herb, which they say can quickly and easily remove "fluoride" from drinking water. The technology described in the March issue of the International ...

Onion soaks up heavy metal, researchers find

Onion and garlic waste from the food industry could be used to mop up hazardous heavy metals, including arsenic, cadmium, iron, lead, mercury and tin in contaminated materials, according to a research paper published in the ...

Researchers develop blue-fluorescent molecular nanocapsules

Michito Yoshizawa, Zhiou Li, and collaborators at Tokyo Institute of Technology synthesized ~1 nanometer-sized molecular capsules with an isolated cavity using green and inexpensive zinc and copper ions. In sharp contrast ...

New material shows promise for trapping pollutants

(PhysOrg.com) -- Water softening techniques are very effective for removing minerals such as calcium and magnesium, which occur as positively-charged ions in "hard" water. But many heavy metals and other inorganic pollutants ...

How microbes take out the trash

(PhysOrg.com) -- The molecular machinery bacteria use to rid themselves of toxic substances including antimicrobial drugs has been studied in detail by a UA-led team of researchers. A better understanding of these mechanisms ...
