Researchers at the University of Alberta in Canada have developed a new analytical technique to detect a harshly toxic arsenic compound that was once difficult to measure (Environ. Sci. Technol., DOI: 10.1021/es100273b). With this new method, scientists may find that the chemical contaminates more groundwater sources than previously thought, the researchers say.

The toxicities of arsenic compounds vary by . . .
