A compact and affordable, microchip-based system for the automated, in situ analysis of inorganic ions in atmospheric aerosols will be develop and verified against traditional, filter-based methods. Our approach combines tow new technologies: (1) a growth tube impactor for particle collection and (2) lab-on-a-chip (LOC) analysis of sulfates and nitrates. The growth tube impactor enlarges indivi ...

Concern for the potential health effects of inhaled particulates led to a federal standard governing coarse particles, or PM10, for particles below 10 ¿m and subsequently to a fine particle (PM2.5) standard in 1997, for particles below 2.5 ¿m. The U.S. Environmental Protection Agency (EPA) retained the PM10 standard because all particles below 10 ¿m can penetrate into the pulmonary region. Be ...

The goal of this Phase I research project is to establish the feasibility of a regenerable chemical sensor for in situ detection of halogenated hydrocarbons (HHCs) in water. The technology is expected to generate a device for rapid field tests related to spills and accidents. HHCs, such as trichloroethylene (TCE), have been widely used for degreasing operations and as dry cleaning agents. They ...

The leading treatments for perchlorate removal are ion exchange with catalytic destruction and bioreactors. These treatments require significant labor and material inputs. The associated operating costs prohibit scaling to small systems (fewer than 25 people or 15 service connections). Even in large systems, the leading treatments are expensive, costing $100-$200/acre-ft, or 20-40 percent of wh ...

Nanomix, Inc., proposes to develop and commercialize nanoelectronic chemical sensors for the detection and measurement of air pollution. The end product of the work, a tiny, low-cost nanosensor chip, will measure concentrations of three different analytes down to the single molecule level. The proposed work is an extension of the gas sensing technology developed at Nanomix, Inc., using carbon na ...

The U.S. Environmental Protection Agency has identified the need for continuous monitors that can operate unattended and provide real-time data on the concentration of the major chemical components of PM2.5, defined as particles with diameters of less than 2.5 µm. The chemical composition of fine airborne particles is needed to identify sources, understand formation mechani ...
