Acute Effects of Lead on the Renal Handling of Zinc in Dogs. VICTERY, W., SOIFER, N. E., WEISS, J. S., AND VANDER, A. J. (1981). Toxicol. Appl. Pharmacol. 61, 358-367. Urinary zinc excretion was monitored in anesthetized dogs before and during 4 hr after acute exposure to lead (doses: 0.3 mg Pb (as acetate)/kg as iv prime, followed by infusion of 0.057 mg Pb/min; 3mg Pb/kg, followed by 0.57 mg ...

Abstract The Iberian Pyrite Belt is a world-class metallogenic district developed at the Devonian-Carboniferous boundary Variscides that currently has seven active mines: Neves Corvo (Cu-Zn-Sn) and Aljustrel (Cu-Zn) in Portugal, Riotinto (Cu), Las Cruces Aguas Teñidas (Cu-Zn-Pb), Sotiel-Coronada La Magdalena (Cu-Zn-Pb) Spain. massive sulfide ores are usually hosted lower sections of volcano-sed...

the study area is located in southeastern iran, about 110 km southwest of kerman. geologically, the area is composed of ophiolitic rocks, volcanic rocks, intrusive bodies and sedimentary rocks. vein mineralization within andesite, andesitic basalt, andesitic tuffs occurred along the chahar gonbad fault. sulfide mineralization in the ore deposit has taken place as dissemination, veins and veinle...

Profiles of some trace elements (Fe Mn, Zn, Cu, pb and Cd) were detected in saline water and surficial sediment of Wadi El-Natrun depression lakes. The trace elements concentrations largely indicate the influence of weathering of terrigenous sources on land. The order of the studied trace elements in brine lakes of Wadi El-Natrun from high to low concentrations are Mn > Pb > Fe > Zn > Cu > Cd a...

The Nii Zn-Pb-Ag-Ba prospect is located in the headwaters of the Noosegolch River valley, approximately 23 kilometms north-east of Hagensborg in west-central British Columbia (Figure 1). The area lies within the Stikine Termne of the Coast Belt and is mostly underlain by various packages of matic to felsic volcanic, volcaniclastic and sedimentruy m&s @gore 1). Many of these packages are of unce...

The coexistence of numerous Mississippi Valley-type (MVT) Pb-Zn deposits and oil/gas reservoirs in the world demonstrates that a close genetic link between them. northern Yunnan–Guizhou depression (NYGD) is tectonic unit containing Pb–Zn deposits, paleo-oil shale gas. However, previous studies on relationship hydrocarbon accumulation mineralization have been ignored. Maoping deposit large-sized...

BACKGROUND Metal pollution of waterways directly affects human health and can impact the food chain. Seafood living in polluted water can accumulate trace metals. The purpose of this study was to analyze the toxic metals Pb and Cd and the dietary essential metals Zn and Mn in 120 cans of tuna species from four different brands processed in Iran and purchased in 2012. RESULTS The mean level of...

Binary and ternary separations of heavy metals, e.g. Zn–Bi, Mn–Pb, Cd–Pb, Mn–Bi–Mo, and Cr–Pb–Bi on columns of titanium(IV) tungstosilicate and Zn–Ni, Mo–Pb, Hg–Pb, Zn–Cr–Bi, and Zn–Ni–Bi on titanium(IV) tungstophosphate, have been demonstrated. The adsorption and elution of important metal ions such as Mo, Al, and As on titanium(IV) tungstosilicate and Hg, Fe, and Cr on titanium(IV) tungstopho...
