Unformatted text preview: dmium on M ammalian Cells ect of cadmium toxicity on mammalian cells by using the bacter ia pseudomonas. There are many toxins in the environment that have an effect on mammalian cells. The National Toxicology Program of the Department of Health and Human Services has developed a long list of known carcinogens and many of them are present in the environment (Department of Health and Human Services). The consumption of cadmium over time is a major concern. 85% of the energy that is used on earth comes from the combustion of fossil fuels (Bartok and Sarofim). Although necessary, the burning of these fossil fuels is causing the release of deadly cadmium into the environment. The cadmium that comes from the burning of fossil and fuels simply contributes to the cadmium given off by many other aspects of daily life. It is important for scientists to perform research involving cadmium because this carcinogen has many different mechanisms to attack healthy cellular systems. Research labs have devoted time and money to attempt to figure out the mechanisms involved in toxins such as cadmium to help figure out a way to combat their negative effects in the environment. Cadmium and Cadmium-containing compounds are known carcinogens that are highly toxic and can cause major damage to mammalian cells. Cadmium reacts in many different mechanisms with bacteria and has been known to have an effect of the growth of many different types of bacteria. Tests on how cadmium affects the bacteria pseudomonas was done in the toxicology lab at Florida Agricultural and Mechanical University in the fall of 2008. This research showed that certain concentrations of cadmium have an affect on the bacteria. Knowing how different concentrations of cadmium effect bacteria is beneficial because it can allow us to control the amount of cadmium in the environment. 2 Cadmium has an atomic number of 48 and an atomic weight of 112.41 grams/mol. It is a transition metal and is very similar to the element Zinc in this and many more aspects. Cadmium and zinc have the same oxidation state and are almost the same size when ionized (U.S. Environmental Protection Agency). Cadmium can actually replace zinc in some biological systems. It binds up to ten times more strongly than zinc and reacts to form more complex compounds, which is why it is more of a hazard than zinc. Cadmium mimics zinc and rarely calcium and iron. There are multiple ways to be exposed to cadmium. It has a significant presence in the environment as well as in areas that affect daily comfortable living....
