Clinical signs ascribable to Zn deficiency were noted in Friesian cows industrially poisoned with Mo. Zn, Cu and Mo were determined in blood serum and black hair, and in the contaminated alfalfa pasture the group grazed on. Hematological parameters, and serum Ca and alkaline phosphatase activity, were also determined. Pooled samples of alfalfa from 2 uncontaminated pastures, and of blood, serum and black hair of clinically normal Friesian cattle grazing on these were used as controls. A mixed contamination of the polluted pasture with Mo and Cu was found, both metals being inversely correlated with the distance to the polluting chimney. Zn concentrations were normal and not significantly correlated with the distance to the chimney. Very high Mo was found in serum and hair of the poisoned animals; Cu was normal in serum and hair. Low Ca and alkaline phosphatase activity were found in serum, both variables significantly correlated with serum Zn. Reduced red blood cell number, packed cell volumes and Hb concentrations, but no significant correlation of these parameters with any of the trace metals in serum or hair, were found. Signs ascribed to Zn deficiency were consistent with the reduction of Zn in serum and hair and decreased alkaline phosphatase activity in serum. A Zn deficiency conditioned by a simultaneous increased intake of Mo and Cu is proposed.

Seasonal changes in the concentrations of Cu, Mo and S in subterranean clover (Trifolium subterraneum), silver grass (Vulpia sp.), Wimmera ryegrass (Lolium rigidum) and capeweed (Arctotheca calendula) growing on lateritic podzolic soils were measured in glasshouse and field studies. The effects of varying soil temperature and water content on the concentrations of Cu, Mo and S in subterranean clover on a lateritic podzolic soil and a calcareous sand were also investigated. similar seasonal patterns in plant composition were observed in the glasshouse and the field. The concentration of Mo remained constant throughout the season but that of Cu and S declined from autumn to spring; the decline was more rapid in the grasses than in subterranean clover and capeweed. Subterranean clover had higher concentrations of Cu and S but lower Mo than silver grass or Wimmera ryegrass. Capeweed contained more Cu and Mo but less S than subterranean clover. The concentrations of Mo and S were similar in capeweed and the grasses. Increasing soil temperature from 12 to 22? C increased the dry matter production and the concentrations of Cu and Mo (but not S) in subterranean clover on both soils. Increasing soil water content slightly increased dry matter production and the concentration of Mo but had no effect on the concentration of Cu and S in subterranean clover. Results were discussed in relation to the health of grazing animals.

Experiments were conducted to study the nature of the relationship between Met, Cu and Fe. Day-old broiler chicks were adapted to an isolated soyprotein-cornstarch diet containing 20% protein, 3300 kcal metabolizable energy (ME)/kg, normal levels of minerals and 0.59% Met (methionine). They were then fed the basal diet, alone or supplemented with 1.5% DL-Met, 2000 ppm Mo, 4000 ppm Mo, or 100, 250, 500 or 1000 ppm Cu for 1 or 3 wk. In contrast to 1.5% excess Met, excess Mo increased plasma Cu concentrations significantly, had no effect on spleen or liver Fe and did not induce neurological changes. Dietary Cu or Met significantly influenced body weight gain and the concentrations of Cu in plasmas or livers. Supplements of 1.5% DL-Met, 500 or 1000 ppm Cu retarded body weight. A direct relationship between dietary Cu and the concentration of Cu in livers or plasmas was demonstrated in chicks fed the basal diet or the basal diet supplemented 1.5% DL-Met. Chicks fed excess Met had lower levels of Cu in plasma and liver at every level of excess dietary Cu. Liver and spleen Fe concentrations were increased by 1.5% excess DL-Met but were not significantly altered by supplementary Cu.

Concentrations of 28 elements in fruiting shrubs downwind of the smelter at Flin Flon, Manitoba, Canada

Berries, leaves and stems of 3 shrubs (Vaccinium myrtilloides, V. vitis-idaea and Arctostaphylos uva-ursi) have higher concentrations of As, Se, Hg, Pb, Cu, Fe and Zn near a smelter operation than farther away. The toxicological implications for wild herbivores of such heavy metal contamination are difficult to determine because of interactions among these metals. As, Se and Pb analyses carried out independently on the same samples were not significantly different.

Hydrothermal stability of beta-cesium diuranate and strontium zirconate in fluids

The stability of beta-Cs2U2O7 and SrZrO3, 2 possible phases of spent fuel elements, in hydrothermal fluids was investigated. beta-Cs2U2O7 was unstable under hydrothermal conditions of 100, 200 and 300? C/300 bars, releasing substantial amounts of its Cs in deionized water and all of its Cs in a bittern (high-Mg and-Ca) brine. SrZrO3 was stable in deionized water, but not in a bittern brine. Sr released into solution decreased from 3.9 to 2.8% with an increase in temperature from 100 to 300? C, probably because of better crystallization of SrZrO3 at higher temperatures. In bittern brine, 23.3, 94.9 and 100% of Sr was released into solution at 100, 200 and 300? C, respectively, as a result of acidic conditions generated by the hydrolysis of MgCl2 and formation of brucite. Apparently, bittern brine which may be encountered in a salt repository was highly corrosive and may release all the Cs and Sr into solution under hydrothermal conditions if the containment were breached. The use of tailor-made overpacks or backfill barriers of high stable and sorptive materials is essential especially in a salt repository in order to minimize the threat of highly hazardous Cs and Sr radionuclides finding their way into ground waters.

Chronic oral administration of ammonium molybdate in rats markedly retarded the growth rate of rats, and high protein diet partially reversed this condition. The activities of several enzymes i.e., acid phosphatase, alkaline phosphatase, glucose-6-phosphatase, succinic dehydrogenase, glutamate oxaloacetate transaminase, inorganic pyrophosphatase and acetylcholinesterase, in different tissues and serum levels of luteinizing hormone, FSH, prolactin and cortisol were altered due to the toxicity, and high protein diet fed group of animals showed almost normal values for some of these parameters. Normal histological pattern of liver and kidney tissues were altered by Mo toxicity. Significant increases of basophilic substances were observed in the cytoplasm of the liver cells of the toxic animals which was counteracted by a feeding high protein diet.

In pot experiments, subterranean clover (T. subterraneum) was grown on 4 soils, 2 lateritic podzolic soils, a red-brown earth and a calcareous sand, to which various combinations of P (0-45 ppm as KH2PO4), S (0-45 ppm as CaSO4), Cu (0-10 ppm as CuSO4) and Mo (0-1 ppm as sodium molybdate) had been added. Applications of S and Cu had little effect on the dry weight of the clover tops on any soil and no fertilizer affected dry weight on the calcareous sand. On the other soils, dry weight was increased by P and by Mo when applied in combination with P. Cu treatment consistently increased the concentration of that element in the tops of the plants. On the lateritic podzolic soils and the red-brown earth, S generally increased Cu and S concentrations but decreased that of Mo; P decreased Cu and S but increased the concentration of Mo. On the calcareous sand, application of S had no effect on Cu but decreased Mo and increased S concentration; treatment with P decreased the concentration of Cu but had no effect on S or Mo in the plant tops. There were significant interactions between all treatments. These were discussed in relation to fertilizer practice and animal health.
