Scanning probe microscopy of environmental interfaces
Article Abstract:
Scanning probe microscopy (SPM) is one of the effective surface analytical techniques developed to be used in various environmental applications. SPM, which has a capacity to image surface shapes and structures to atomic levels, belongs to a line of technique that results to digital images based on interactions between a sharp tip and a surface. The procedure can be employed in applications such as situ imagery, quantification of surface reaction rates, energies and other physical and chemical properties. SPM also allows measurement of key energetic parameters for reactive sites found on mineral surfaces.

Mercury test method could lower discharge limits
Article Abstract:
The EPA's step to analyze minute levels of mercury in water, with the Method 1631, probably will caution violators of the Clean Water Act. Mercury, a toxic element regulated at 12 parts per trillion (ppt), sometimes get discharged due to a lack of an approved detection test. Method 1631 detects mercury about 200 times more sensitively than the current method and can measure levels of 0.5 ppt. The agency feels that the proposal would force companies and waste treatment plants to reduce mercury discharges.

Promoting your environmental web site
Article Abstract:
There are a number of issues that science and technology organizations should consider before establishing a web site. Organizations should first consider whether it is cost-effective to establish a site at all. Other steps include using a professional search engine listing firm, creating pages that can catch the interests of web users, and listing a site at search engines for free.
