In environment cadmium transfers from one trophic level to another and finally accumulated in human with toxic effects. There is an emergent need to remove the cadmium from environment. Microbes are very helpful in this area to remediate the cadmium from environment. Microorganisms used biotransformation and adsorption mechanisms for regulation of translocation ofRead MoreThe Food Of Organic Foods1413 Words   |  6 Pagespollution. To start, organic foods have a more nutritional value that leads to a healthier lifestyle. For instance, many of the organic foods have been found to be higher in vitamin C, antioxidants, and natural minerals like calcium, iron, chromium and magnesium. Most of these nutrients are the main components of a human’s nutrition. Non-organic foods could be causing certain foods to become less nutritional for a person eating. The less nutrition a person has, the more they are at risk toRead MorePlant Pudina4642 Words   |  19 PagesNAME:-PUDINA This plant is related to the menthe genus and its aromatic herbs.
