Cadmium: ''Avoid over exposure''

Cadmium is a chemical element that is distinctive for its bluish white appearance and is similar to zinc and mercury. Compared to other metals it has a feature that other ones do not possess it. It is resistant to corrosion thus it is applied as a protective layer in other metals. However, cadmium if inhaled by humans through fine dust and fumes, can be potentially harmful. Tobacco smoking is the most common exposure of cadmium for the population. This leads to appearance of serious medical conditions such as hypertension and atherosclerosis.
Across the world there are some studies that investigate the consequences from cadmium exposure. A Chinese study carried in 2004 was an epidemiological one and it compared individuals that had high exposure of cadmium and other that did not have. It involved a total of 790 people, some of them had a residence in areas that were close to lead, cadmium and zinc smelter and other were in an area free from any exposure. Measurements of this study suggested that people were subjected to exposure to the various metals, including cadmium, experienced loss in mineral density associated with osteoporosis and increased risk of fractures. There was a study also carried in United States also at 2007. In this study bone measurements were collected from people. These showed significant damage and it was proved that apoptosis is induced by cadmium which leads to disruption of normal life that is further related to the imbalance of bone formation.
Therefore it is recommended that exposure of cadmium should be in few amounts otherwise there are several risk factors that can pose a severe risk for the health. It is resistant to corrosion and it is highly toxic when inhaled.
