 · The environmental cycling of mercury (Hg) can be affected by natural and anthropogenic perturbations. Of particular concern is how these disruptions increase mobilization of Hg from sites and alter the formation of monomethylmercury (MeHg), a bioaccumulative form of Hg for humans and wildlife. The scientific community has made significant advances in recent .

 · Negative air ions (NAIs) have been discovered for more than 100 years and are widely used for air cleaning. Here, we have carried out a comprehensive reviewing on the effects of NAIs on humans/animals, and microorganisms, and plant development. The presence ...

Leaded Dust Removal and Control A. Introduction More children become lead poisoned from leaded dust than any other form of exposure. Removing leaded dust can protect children, but because leaded dust is so small, it cannot be seen by the naked eye so special cleaning methods are needed to make sure you get rid of all the harmful dust.

 · A critical issue that must not be overlooked is that weld preparations or beveling must be monitored for the unhealthy fumes that are produced during the operation. When certain metals are heated, fumes are released by the combination of the heat and the metal. Always know what specific metals are being used when working with a heat source.
