1 Cadmium is a soft, malleable metal that is found in the earth's crust. Cadmium emissions can originate from several anthropogenic sources from the burning of fossil fuels or trash, smoking cigarettes, pesticides, or manufacturing activities. As it is naturally found in the earth, it obviously can be found naturally. Natural sources of cadmium include the weathering of rocks to volcanoes and forest fires to certain foods (Lenntech, 2011).
Health effects of cadmium are wide-ranged. Acute effects can result in bronchial and pulmonary irritation, which can be long-term. Chronic effects include frequent formation of kidney stones, emphysema, and damage to vital organs and nervous systems ...view middle of the document...
I had no idea that cadmium could be produced from the burning of cigarettes. It seems to always come down the way to improve our air quality is to reduce the burning of fossil fuels. I would assume cadmium emissions to be higher during the summer months compared to other times of the year, or least hot days than coller days. The air during that time seems to be stagnant.
3 There have been reports of Cadmium found in McDonalds shrek glasses, kids jewelry, and items used to create protein drinks. The health affects on the kidneys will cause them to work harder. This target organ of the kidney is a vital organ that processes the heavy metal. Belive it or not, in some area, earth worms are an invasive species. The species are not native, but have been in area for many years. The cadmium in the soil and then absorbed in earthworms will still change the food web. Contaminated soil has to be disposed of properly. The metal is used in batteries as well. The cadmium found in batteries can ignite when not used properly. Using the wrong charger, or exposing them to heat will release the toxic metal in the atmosphere. One exposed, the material, cadmium will cause a health issue.
4 Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. ("Volatile Organic Compounds (vocs)", 2012). Volatile organic compounds are released from burning fuel, such as gasoline, wood, coal, or natural gas. They are also released from solvents, paints, glues, and other products that are used and stored at home and at work.
Many volatile organic compounds are also hazardous air pollutants. Volatile organic compounds, when combined with nitrogen oxides, react to form ground-level ozone, or smog, which contributes to climate change. ("Volatile Organic Compounds (vocs) ", 2012). VOC’s are usually classified as having a high vapor pressure that vaporizes entering the atmosphere. The organic compounds are classified according to their functional group. There are four major types of compounds found in all living organisms - carbohydrates, lipids, proteins and nucleic acids. These molecules form long chains of similar subunits or polymers. They are very large molecules and therefore called macromolecules. The subunits of polymers are called monomers.
5 Volatile organic compounds are extremely flammable. VOC's are found in a lot of household products as well. These chemicals should be stored in a properly cabinet to help reduce the risk of vapors being emitted in to the air, or catching on fire. VOC's can be found in ground water, but not usually in surface water because it evaporates so quickly. Volatile organic compounds in the drinking water higher that the EPA standard can lead to problems with the central nervous system, the kidneys or the liver. The target organ of the liver and kidneys are expected because they are filters for the body....
