Wastewater from coal-fired power plants is linked to a wide range of environmental and human health concerns. Measuring low levels of toxic trace metals in these wastewaters is complicated, however, by high levels of interfering matrix elements. A new EPA method using ICP-MS addresses this analytical challenge.
