Drinking water quality standards - Wikipedia
In the USA, the federal legislation controlling drinking water quality is the Safe Drinking Water Act (SDWA) which is implemented by the EPA, mainly through state or territorial primacy agencies. States and territories must implement rules that are at least as stringent as EPA's to retain primary enforcement authority (primacy) over drinking water.

There’s Plenty of Room at the Bottom. —Richard Feynman With the recent demise of Milly’s electron emitter, I attempted to make a new one.Much to my surprise, it worked. Turns out making small things is harder than it might seem.
Carbon - Element information, properties and uses ...
150 years ago the natural concentration of carbon dioxide in the Earth’s atmosphere was 280 ppm. In 2013, as a result of combusting fossil fuels with oxygen, there was 390 ppm.
Chlorine - Wikipedia
Chlorine is the second halogen, being a nonmetal in group 17 of the periodic table. Its properties are thus similar to fluorine, bromine, and iodine, and are largely intermediate between those of the first two.Chlorine has the electron configuration [Ne]3s 2 3p 5, with the seven electrons in the third and outermost shell acting as its valence electrons.
Silver - Element information, properties and uses ...
Silver bromide and iodide were important in the history of photography, because of their sensitivity to light. Even with the rise of digital photography, silver salts are still important in producing high-quality images and protecting against illegal copying.

International Journal of Spectroscopy - Hindawi
This stone is a review of optical methods for online nondestructive stone quality monitoring. The key spectral areas are the visual and near-infrared wavelengths. We have collected the information of over 260 papers published mainly during the last 20 years. Many of them use an analysis method called chemometrics which is shortly described in the paper.

Molecular weights can be found in the NIOSH Pocket Guide to stone Hazards, stone supplier lists, the NIST Chemistry WebBook or other online databases.. The numeric value of 24.45 in both formulae is the molar volume of air in litres at normal temperature and pressure (NTP), which is considered to be 25ºC and 1 atmosphere (101.325 kPa or 760 mm Hg or 760 torr).

ABSTRACT. Nanocomposites, a high performance material exhibit unusual property combinations and unique design possibilities. With an estimated annual growth rate of about 25% and fastest demand to be in engineering plastics and elastomers, their potential is so striking that they are useful in several areas ranging from packaging to biomedical applications.

The hatchery culture of bivalves: a practical manual
A recovery of from 30% to 85% perfectly formed D-larvae from the initial number of embryos stocked is normal in large-scale rearing. Imperfectly formed D-larvae - those with incomplete or misshapen shells - rarely develop further.
