Three sets of experiments were carried out to determine if there is an intestinal secretory component in the fecal excretion of administered inorganic mercury. In the first set of experiments the disposition of a nontoxic 0.5-micromol/kg intravenous dose of inorganic mercury was evaluated in control rats and rats whose bile duct had been ligated. Data collected 24 h after the administration of ...

The influence of different anions on the stability of mercury in absorbing solutions containing sulphite ions was investigated. The re-emission of gaseous mercury in the presence of fluoride, chloride, bromide, nitrate, carbonate and sulphate ions from the scrubbing solution was determined. Fluoride, chloride and bromide ions contribute to mercury stabilization, bromide being the most efficient...

use of microorganisms for removing mercury is an effective technology for the treatment of industrial wastewaters and can become an effective tool for the remediation of man-impacted coastal ecosystems with this metal. in this study, seven types of mercury resistant bacteria were separated from industrial waste and minimum inhibitory concentration (mic), were determined for these bacteria. resu...

It is well known that mercury is ac cumulated in the kidney and causes renal failure. Mercury has been a subject of extensive study, but a definite mechanism for its biochemical toxicity remains to be elucidated. In a previous paper (1), we reported that mersalyl (mercurial diuretic) had a more powerful stimulatory effect on the lipid peroxidation in renal cortical mito chondria than any other ...

The histochemical technique of autometallography was used in the present study to demonstrate the zonal and tubular localization of inorganic mercury in the kidneys of unilaterally nephrectomized (NPX) and sham-operated (SO) rats given either a nontoxic 0.5 mumol/kg or a toxic 2.5 mumol/kg dose of mercuric chloride 10 days after surgery. Deposits were found in the cortex and outer stripe of the...

Liquid ammonia, trialkyl phosphites, and especially trialkylphosphines, are very powerful electron-pair donor solvents with soft bonding character. The solvent molecules act as strongly coordinating ligands towards mercury(ii), interacting strongly enough to displace halide ligands. In liquid ammonia mercury(ii) chloride solutions separate into two liquid phases; the upper contains tetraamminem...

Introduction: Environmental pollution with heavy metals such as mercury is a major health problem. Growing studies on the field have shown the deleterious effects of mercury on human and nonhuman nervous system, especially in infants, however the effects of prenatal exposure to mercuricchloride on cortical development are not yet well understood. The aim of this study was to investigate the eff...

In the present study, an efficient mercury-tolerant bacterial strain (RS-5) was isolated from heavy-metalcontaminated industrial effluent. Under shake flask conditions, 97% of the supplemented mercuric chloride was sequestered by the biomass of RS-5 grown in a tryptone soy broth. The sequestered mercuric ions were transformed inside the bacterial cells, as an XRD analysis of the biomass confirm...

A mercury-resistant bacterial strain which is able to reduce ionic mercury to metallic mercury was used to remediate in laboratory columns mercury-containing wastewater produced during electrolytic production of chlorine. Factory effluents from several chloralkali plants in Europe were analyzed, and these effluents contained total mercury concentrations between 1.6 and 7.6 mg/liter and high chl...
