Ecotoxicity assessment of a molybdenum mining

921ensp;0183;ensp;Comparing the values determined in the effluent with the discharge limits of pollutants from mining and mineral processing industry in the Chinese national standard (GB 286612012) (MOEP 2012), the pH (3.95) exceeded the limit range (69); trace metals Zn, Cu, Mn, and Cd were outside their upper limits by 7.15, 18.48, 7.65, and 2.6 fs of the effluent limit, respectively.

Molybdenum Health Professional Fact Sheet

2 ensp;0183;ensp;Acute molybdenum toxicity is rare, but it can occur with industrial mining and metalworking exposure. In healthy people, consumption of a diet high in molybdenum usually does not pose a health risk because the molybdenum is rapidly excreted in urine [ 1 , 14 , 18 ].

Molybdenum uptake, absorption and excretion in

A recommended daily allowance of molybdenum for an adult has been established at 0.2 mg [Dulce, 1968]. In addition daily molybdenum intakes from drinking water and ambient air are almost neglible and should be considered only in molybdenum mining areas.

Molybdenum in Drinkingwater WHO

Levels of molybdenum in drinkingwater do not usually exceed 10 181;g/l (Greathouse amp; Osborne, 1980). However, in areas near molybdenum mining operations, the molybdenum concentration in finished water was reported to be as high as 200 181;g/l. Tapwater concentrations as high as 580 181;g/l have been reported in Colorado (Chappell, 1973).
