Gold mining in Idaho and other western states has left a legacy of heavy metal contamination. These metals enter the food chain via plants and water, and are toxic to living organisms. There is a need to identify and map the heavy metal contamination, and to track the fate and transport of heavy metals from one mine site to another via surface waters. Our hypothesis is that the severe contamination in the area of the Missouri Mine is not all from that site, but includes heavy metals transported in surface water from another mine to the northeast, in the Summit …

Water-borne pollutants such as volatile organic compounds are a serious environmental concern, which has increased the demand for chemical sensing elements. Solidstate sensors based on catalytic gate devices are a subject of current research, however they are restricted in practical applications because of their inability to operate at room temperature. Conducting polymer FETs, which employ a conducting gate polymer, have received much attention due to their unique electronic and optical properties. Polythiophene is chosen as the semi-conductive gate polymer in this work. A functional group attached to the polythiophene is used to detect analytes (i.e., mercury in this work) of …
