Examples of more dangerous pathogens and chemicals that might contaminate or become attached to more-ordinary house dust particles (such as fabric fibers, soil particles, even skin cells in house dust) include the following: Arsenic, e.g. from old wallpaper, wear & tear Heavy metals, other co...
(PPE). This might be as simple as a lab coat, goggles, and rubber gloves, or as thorough as a full-body chemical-resistant suit with a special face mask to filter air. Based on the hazard, different PPE have different levels of sophistication, and each situation where exposure is ...
The eventual discovery of promethium is described all too briefly in my essay and is covered in much more detail elsewhere, including the sources I mention near the start of this post. To summarize, it was isolated from the fission products of uranium during the Second World War at Oak Ridg...
final molecular model. MM calculations give an insight into molecular geometries and energies. In practice, a variety of programs offer MM calculations, for example, HYPERCHEM or Sybyl (Tripos). A variety of examples for the application of molecular modeling and MM calculations in chemistry are di...
As a result of the investigation, the cause was identified as waste water discharged from the kitchen, and (1) a request was made to the kitchen supplier to take through measures to prevent contamination with oil etc., and (2) measures were taken to clean the pipes in the kitchen system...

Incineration under the right conditions can effectively eliminate this hazard. Disposed products containing fluorocarbons (Teflon-coated ware, some personal-care, waterproofing and anti-stick materials) break down into perfluorooctane sulfonate which has been shown to damage aquatic animals. Hazards of ...
[114,115]. When piezoelectric materials participate in photo-electro-chemical reactions, the piezoelectric polarization acts as an adjustment for the barrier height of the semiconductor at the interface, where electronic energy states can be influenced strongly. Two examples of electric charge transfer ...
