Air contaminants databases ease healthy homes planning
February 16, 2007Air pollution sources are everywhere in the home, from the bacon and eggs frying in the kitchen, to the woodburning stove in the family room, the newly painted hallway, and even the carpet in the living room. To help estimate the seriousness of these and other indoor pollutant sources as well as to devise ways to reduce possible health impacts, the National Institute of Standards and Technology (NIST) has developed searchable databases of relevant product emission studies.
NIST researchers also have created a software tool called ContamLink that can transfer selected information from the databases into CONTAM, an indoor air quality modeling software program that predicts airflows and contaminant concentrations in multizone building systems. Together—the electronic databases, ContamLink, and the CONTAM program—should significantly accelerate our understanding of indoor air pollution.
The new databases allow investigators to access immediately information that previously was available in scientific literature, but required significant time to locate. The databases include emission rates for consumer products, cooking and combustion appliances (such as gas stoves); and data on contaminant transport mechanisms, including particle deposition, contaminant sorption and different ventilation systems filters. Two of the five databases are from the U.S. Environmental Protection Agency (EPA) and the National Research Council of Canada. Researchers can download the databases, and with ContamLink, selectively obtain relevant information for inclusion in CONTAM or other indoor air quality models. Database entries are not intended to be all-inclusive, but rather representative of the literature. Researchers and other practitioners are encouraged to expand the databases with their own data using the data entry format provided.

NOAA, USFWS study finds potential disease threats to Washington sea otters
Many of Washington State's sea otters are exposed to the same pathogens responsible for causing disease in marine mammal populations in other parts of the country.
Newly described contaminant sources in Katrina-flooded homes pose health risks
Post-Katrina flooded homes may contain harmful levels of contaminants in addition to sediment deposits. Indoor gases, mold films, and aerosols may also have exposed residents, first responders, and demolition crews to dangerous contaminant levels without the need for direct skin contact.
Termite insecticide a potent greenhouse gas
An insecticide used to fumigate termite-infested buildings is a strong greenhouse gas that lives in the atmosphere nearly 10 times longer than previously thought, UC Irvine research has found.

Auto Detailing Contaminants Removing Block Magic Shine Eraser by Candie's eStore The Magic Shine Eraser is the best substitute for traditional hard to use clay bar. It actually works better, easier, and more effectively. This is an eco-friendly product because all it needs to use with is water, no more chemical lubricant. Magic Shine Eraser is safe to be used on painted surfaces, glass, chrome and wheels. Wash car. While the vehicle still wet, hold Magic Shine Eraser rubber side against the surface and glide it back and forth GENTLY. Dont press it hard onto the surface and rub it roughly. Repeat the gliding motion with water until you feel the surface is smooth |

Contaminants of Emerging Environmental Concern by Environmental and Water Resources Instit (Author) A new category of contaminants is capturing the attention of citizens, scientists, and regulators. Anthropogenic chemicals occur in air, soil, water, food, and in human and animal tissues. This report considers specific pollutants such as pharmaceuticals, personal care products, antimicrobials and antibiotics, hormones, plasticizers, surfactants, fire retardants, pesticides, and nanoparticles. It is a must-have for undergraduate and graduate students in environmental engineering and resources; teachers; researchers; and practicing environmental engineers. |
