Agricultural drainwaters

Elevated levels of molybdenum in nonbiological materials have been reported near certain mines, power plants, and oil shale deposits, as well as in various sewage sludges, fertilizers, and agricultural drainwaters (Table 30.1). Molybdenum is concentrated in coal and petroleum, and the burning of these fuels contributes heavily to atmospheric molybdenum (King et al. 1973). Combustion of fossil fuels contributes about 5000 metric tons of molybdenum annually to the atmosphere atmospheric particulates contain about 0.001 pg Mo/m3 air (Goyer 1986).

Boron occurred at high concentrations in plants, insects, and fishes at KNWR in California - the recipient of contaminated agricultural drainwater - when compared to a nearby control area. Both boric acid and borax produced mortality and teratogenic development when injected into eggs. The effects of boron on waterfowl growth, physiology, and reproduction are discussed later.
