All-purpose detergents remove lead-contaminated dust from household surfaces just as effectively as high phosphate detergents and lead-specific cleaning products, according to new research scheduled for publication in the Jan. 15 issue of the American Chemical Societys Environmental Science & Technology journal.
The researchers, led by Roger D. Lewis, Ph.D., CIH, of the Saint Louis University School of Public Health, tested how well various detergents removed lead from three common household surfaces: vinyl flooring, wood and wallpaper. They determined that all-purpose floor detergents containing no phosphate did just as well as a more expensive lead-specific product and trisodium phosphate (TSP), a less environmentally friendly substance. Lead-specific cleaners or TSP have long been recommended for lead removal.
Of the approximately 100 million housing units in the United States, about 24 million have significant levels of lead in dust, soil and paint, according to the U.S. Department of Housing and Urban Development (HUD). New HUD guidelines, to be released in 2006, will incorporate the findings from this research, according to Lewis. The study was funded by HUDs Office of Healthy Homes and Lead Control.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
