Source receptor modeling of airborne particles collected over the Great Lakes
High-volume air samplers were used to collect aerosol samples on Whatman 41 air filters at the Canadian air sampling stations Burnt Island, Egbert and Point Petre. Once collected, the samples were analyzed for trace elements by neutron activation analysis. Air concentrations of over thirty trace …

Incident-response monitoring technologies for aircraft-cabin air quality
Poor air quality in commercial aircraft cabins can be caused by volatile organophosphorus (OP) compounds emitted from the jet engine bleed air system during smoke/fume incidents. Tri-cresyl phosphate (TCP), a common anti-wear additive in turbine engine oils, is an important component in today’s …

High-precision isotope ratio measurements of uranium and plutonium in the environment
… have been carried out on stratospheric air filters from Sweden and ground-level air filters from Germany.<br/>Application IIA: Plutonium isotopes have been measured in a sediment core from the Wyre saltmarsh. Radionuclide contamination in this area is much higher than in many other UK …

Compact, Self-Cleaning Wet Electrostatic Precipitators
Clean air is essential for public health, but current air filters often come with trade-offs— they remove harmful particles effectively but cause high pressure drops and need frequent replacements. In this project, we developed a new kind of air-cleaning system. Our design allows air to flow freely …

Assessing the relationships between household mold exposure and asthma status in children nationwide sampled by the 2003 national asthma survey
… household mold exposure (OR=1.37, p=.021), air cleaners/purifiers (OR=1.85, p=.001), and gas used for cooking (OR=1.91, p=.006) to be statistically significant positive indicators of current asthma. For lifetime asthma, the same environmental exposures were found to be statistically …

Advancing Direct-Spun Carbon Nanotube Textiles, From Field Alignment to Innovative Applications
… involved the design and production of active air filters using ultra-thin carbon nanotube electrically conductive membranes, mechanically supported by a porous polyester backing. Filtration efficiencies were measured up to 99.999%, while ultra-thin materials with low areal density (0.1 g m-2) …

Assessing the Impacts of Silver Nanoparticles on the Growth, Diversity, and Function of Wastewater Bacteria
… into a wide range of consumer products, such as air filters, washing machines, and textiles, due to their antimicrobial properties [1]. However, despite the beneficial applications of AgNPs into consumer products, it is likely that their use will facilitate the release of AgNPs into wastewater …
