An open-source nanotechnology recipe for magnetite nanocrystals requires only such simple ingredients as olive oil, lye, olive oil soap, vinegar, oleic acid, crystal drain opener, and rust.

is this called nanoremediation?

you know how i "killed" the stench fromdead insects, molds forming in stagnant water that my branch of Zamio Zamiifolia was in (a coconut aluminum can)? by using Glade btterfly garden spray-fragrant flowers;

question: what is in it?

couldn't they use compressed air instead of butane or propane in spray cans like canola oil spray or glade mists or scented sprays...

If in the Midwest, please urge your state legislators to attend

The Environment, Health and the Future - 2009 Policy Summit
January 29-31 – Blackstone Hotel in Chicago

Superfund Basic Research Program
National Conference of State Legislatures

The overarching goal of the workshop is to translate research into knowledge that is important to legislators in the center of the country. The University of Iowa and the National Conference of State Legislatures (NCSL) are co-sponsoring this workshop, primarily through the Iowa Superfund Basic Research Program (isbrp). The goal is to bring science to the process of creating state environmental policy on the following issues: 1. Polychlorinated biphenyl (PCB) in the Great Lakes region and new chemicals; 2. Healthy Homes and Buildings-lead, radon, energy efficiency and regulations. 3. Adaptation to climate change through flood preparation and renewable energy production.

National Environmental Health Association(NEHA)

The National Environmental Health Association (NEHA) is
sponsoring a 2½ day (all expenses paid) training in Washington,
DC. The training is designed to enhance your efforts to implement
radon-resistant new construction (RRNC). You will work with
EPA staff, NEHA field partners who have successfully implemented
RRNC in their communities, local code officials and builders, other
national affiliate partners, and nationally recognized instructors.
You will see specific examples of how to develop an effective, results oriented
program. And, you will develop your own comprehensive
strategy to guide you in your efforts in promoting RRNC as part
of your radon risk reduction strategy. The training will include an
extensive overview of RRNC techniques and presentations on radon
health effects, including recent research.

Applications must be received by the close of business on
Monday, January 19.

Subject: Top Government Officials Will Explain Nanotechnology Regulatory Plans at FDLI Conference Feb. 18-19 in D.C.

The Food and Drug Law Institute, in partnership with Burdock Group and Arizona State University, has assembled the top officials at the agencies responsible for the regulation of nanotechnology products—including the Food and Drug Administration and the Environmental Protection Agency--to discuss their plans for managing and monitoring these products at the 2nd Annual Conference on Nanotechnology, Law and Regulation.

FDA speakers include: Norris Alderson, FDA Nanotechnology Task Force; John Weimer, Office of Chief Counsel; Subhas Malghan, Center for Devices and Radiological Health; Linda Katz, Center for Food Safety and Applied Nutrition; Mitchell Cheeseman, Center for Food Safety and Applied Nutrition; and Douglas Throckmorton, Center for Drug Evaluation and Research. Jessica Barkas, Program Attorney in the Chemical Control Division of the Environmental Protection Agency, also will be speaking at the meeting.

Other featured speakers and moderators include: Scott Livingston, Capital Management/The Livingston Group; Andrew Maynard, Woodrow Wilson International Center for Scholars; Sean Murdock, NanoBusiness Alliance; Jay Ansell, Personal Care Products Council; John Howard, Public Health Law Program, Centers for Disease Control;Erli Chen, Nanotechnology Commercialization Group, NTI; and Steffi Friedrichs, Nanotechnology Industries Association.

Stochastic aspects of primary cellular consequences of radon inhalation.

Stochastic aspects of primary cellular consequences of radon inhalation.
Radiat Res. 2009 Jan;171(1):96-106.

The present calculations with our composite microdosimetric model confirm the assumption that the strong inhomogeneity of radon progeny deposition within the central respiratory passages results in non-uniform local distributions of radiation dose along the epithelium of the bronchi. The “hot spots” of nuclide deposition close to the carinal ridges are transformed into more widely dispersed high radiation dose areas around the bifurcation units of the airways, but dose is still distributed inhomogeneously among the cell nuclei of the epithelium. On a log-log scale, the number of hit cell nuclei decreases linearly as a function of the number of hits per cell nucleus. In the case of the exposure lengths analyzed in this study, the cell nuclei receiving multiple hits are located mainly in the neighborhoods of the carinas. In spite of the fact that maximum cell nucleus doses were found among these nuclei, the cells possessing high transformation probabilities were not restricted to the cells whose nuclei were hit more than once. This phenomenon can be explained with the help of our results obtained for cell inactivation probabilities, according to which a considerable number of the hit cells have high inactivation probabilities, independent of the number of hits. Only a very small percentage of the cell nuclei of our tracheobronchial geometry model were actually hit by α particles. As a consequence, orders of magnitude increases were observed in the mean nuclear dose and cell transformation probabilities if only the exposed cell nuclei were considered instead of all the cell nuclei. The maximum doses and transformation probabilities were close to the mean values if only the exposed cells were considered. On a log-log scale, the maximum dose increases as a function of the number of inhalations. The maximum transformation probability asymptotically approaches its maximum of 10−3. This phenomenon can be elucidated by the fact that high doses yield high inactivation probabilities that prevent cell transformation by killing the cell. The sum of the nuclear doses, the number of the killed cells and the number of the cell transformations vary in linear fashion as a function of the number of inhalations. Thus, based on the model applied in this work, an LNT relationship exists between the number of cell transformations and the length of exposure in case of radon inhalation.
