Arsenic does not just kill people in murder mysteries. The metalloid is poisonous, and long-term exposure at low levels leads to health problems such as skin, bladder, lung and prostate cancer. Arsenic exposure has been linked to a host of other ailments and developmental problems. A team from Texas Tech University in Lubbock and the US Geological Survey National Water Quality Laboratory in Denver has developed a detection tool that can help people avoid arsenic. It did so by exploiting a chemiluminescence reaction involving ozone and arsine (AsH3), an arsenic-containing gas, to detect...Read full article
