Many people do not know about the everyday objects that give off radiation that is effecting the health of people. Things that people come in contact with containing radiation every day include soil, which contain radioactive particles, drinking water, natural gas, and consumer products. The consumer products include glass, computers, ceramics, clocks, phones, lamps, television, and watches. All of the products allow for the possibility of radiation…

Sami, 1991). Figure 3.5 Isomers of asphlathenes (Retrieved from Chemistry of Petrochemical Processes, 2nd Edition, 2001) 2.4 Bioremediation Bioremediation means to use biological organisms to solve an environmental problem such as contaminated soil or contaminated water. In other words it is a biological technology method for removing pollutants from the environment thus restoring the original natural…

Hanford sits on a site in Southwestern Washington that is approximately 586- square miles of desert. Hanford began in 1943 building nuclear reactor plants to produce plutonium for the bomb that would end World War II.

It is an obligate anaerobic, spore-forming, gram-positive, rod shaped bacteria. Botulism was discovered by Émile van Ermengem in 1897 after a contaminated piece of ham poisoned thirty people. He was the first to isolate the bacteria, and determined that C. botulinum was capable of producing heat-resistant endospores. He is also credited with discovering the deadly toxin C.…

Climate change is known to be the changes that happen to the normal climate pattern affecting the surface temperature, humidity rate, average density and rainfall rate, etc. climate change started to appear in the mid 20th century and onward. According to Noaa, (2016), data showed that the global temperature increased by almost two degrees. It seems to be not much but as scientists expected, it affected the global climate in a very negative way. Pollution, global warming, human activities and…

The more obvious and likely was the contamination by over-dilution of the known solution. Despite proper laboratory methods, the possibility of excess DI water or remnants of the previous concentration of the solution being retained in the vessels as they were mixed and transferred from pipette…
