Molybdenum in the environment

Baseline risk assessment of ground water contamination at the uranium mill tailings site near Salt Lake City, Utah. Revision 1

“…For the South Vitro Ditch, a relatively high concentration of molybdenum is assumed t o be available t o plants because higher availability of this element has been documented for waterlogged soils. This availability occurs as inundation produces reducing conditions that release molybdenum from iron molybdate (Jarrell et al, 1980). The concentrations of molybdenum in plants growing in and along the South Vitro Ditch were not measured.…”

“…According t o Jarrell et al (1980), molybdenum has never been shown t o reach toxic concentrations for field-grown crops. However, it is known t o be phytotoxic t o some agricultural plants at concentrations of 2 t o 10 mg/kg (Kabata-Pendias and Pendias, 1992).…”

“…Birds and mammals are comparatively tolerant t o a high dietary intake of molybdenum (Eisler, 1989). For example, mule deer tolerate 10 times more molybdenum in their diet than cattle (Jarrell et al, 1980 …”

Chemical models of inorganic pollutants in soils

“…Many computer-based algorithms have been developed in response to this Volume 15, Issue 1 need for a numerical representation of the ion-association model. 5 ' Four of the best known of these algorithms are summarized in Table 3. Each one represents different subjective choices in respect to parameter selection and numerical method, but each is subject to the same set of quality criteria: accuracy of the data base and verifiability of the predicted species concentrations by comparison with measured values whenever possible.…”

PHOSPHORUS-MOLYBDENUM RELATIONSHIP IN SOIL AND RED CLOVER (Trifolium pratense L.) ON AN ACID ANDISOL

“…Moreover, López et al (2007) found a positive correlation between both, red clover yield and shoot Mo concentrations with soil Mo availability in Chilean Andisols. Jarrel et al (1980) reported that Mo toxicity in animal diet is dependent, between other parameters, of cupper (Cu) concentration in the same one. Thus, soil Cu supply has been shown reduced Mo toxicity.…”
