Adios and Vaya con Dios Molybdenum
Molybdenum is the 42nd element on the periodic table, at room temperature it is a solid and is a silvery white color. It has 42 electrons, 42 protons, and 56 neutrons. Molybdenum has many uses from the field of battle in tanks to X-ray machines. I will discuss a brief history of Molybdenum, how Molybdenum is extracted, how much is left on earth, the political, environmental, and societal effect also the plans for a sustainable future (or lack thereof).
Molybdenum is an old element. There are traces of it through history all the way back to the ancient Greeks. the name comes from Ancient Greek Μόλυβδος molybdos, meaning lead ("Molybdenum"). Molybdenum is a silver metal that has properties much like that of lead and was frequently used in pencils. In WW1 molybdenum was found when smelted with Iron it strengthened the metal greatly. It was put on tanks as armor and allowed them to be a lot lighter and a better protected with less weight from the armor. After WWⅠ the demand for molybdenum decreased greatly. When WWⅡ came to Europe molybdenum was again used to protect tanks and also build ships and ammunition for …show more content…
Molybdenum is found in about 1 to 1.5 ppm. It is about as common as tungsten and many of the rare earth elements.about two-thirds of molybdenum comes from Canada, Chile, and the United States. In the United States, molybdenum ores are primarily found in Alaska, Colorado, Idaho, Nevada, New Mexico and Utah (Encyclopedia.com). Molybdenum makes up 0.00011% of the earth's crust (Periodic Table). Mines in the United States mined 65,500 metric tons of molybdenum in 2014 (Molybdenum mining) Earth crust: 2.8x 1022 Kg of which 70% is water… Therefore we can only use 30% of this for mining This is: 8.4 x10 21 Kg 0.0000011 of 8.4 x10 21 Kg= 9.24e+15 . 1.410687e+27•1016/65.500=20.31255 years left of minable molybdenum if it's mined as vigorously as it is right

pathogens that may be present in the biosolids can be deposited on plants, either directly from application operations or indirectly by vectors. Virus transport from soil to plants has been suggested as a possible route of exposure, but no definitive research has shown this to occur (Straub et al.1993). Planting restrictions are applied on biosolids-amended fields to ensure that contamination of plants is minimized until die-off of any residual pathogens have occurred and risks are reduced. Potential…
