The U.S. Environmental Protection Agency (EPA) has announced it will regulate mercury emissions from coal-fired power plants, with proposed regulations to be issued in 2003. The feasibility and cost of achieving mercury emission reductions is thus a subject of considerable current interest. To assess mercury control options, the Integrated Environmental Control Model (IECM) developed for the U....

Oxidized mercury species may be formed in combustion systems through gas-phase reactions between elemental mercury and halogens, such as chorine or bromine. Injection of bromine compounds or brominated sorbents have been shown to affect mercury speciation and removal in coal-fired power plants. This study examines how bromine species affect mercury oxidation in the gas-phase. Experiments were c...

The use of DMPS as a diagnostic tool in patients with symptoms allegedly caused by mercury from dental amalgam fillings is disputed. We have previously shown that the mercury concentrations in urine cannot be used in such a way. In the present study, we wished to evaluate the effect on blood mercury levels (B-Hg) following intravenously injected DMPS in four groups of subjects: 19 controls with...

A 42-year-old man was admitted to the Nephrology Department because of nephrotic syndrome. Eight months prior to admission he attempted suicide by intravenous self-injection of 2.5 ml of elemental mercury. Renal biopsy was performed. Light microscopy findings showed normal glomeruli and injury of proximal tubular cells. Immunofluorescence was negative, and electron microscopy study revealed dif...

The objective of this study was to identify the presence of harmful drug residues (Chloramphenicol and malachite green/gentian violet) and toxic heavy metals (lead, cadmium, arsenic and mercury) in imported tilapia fillets. A total of 36 tilapia fillets were analyzed for these harmful chemical contaminants. The presence of veterinary drug residues were identified using competitive ELISA screeni...

The application of batch injection analysis to the determination of trace metals in samples of volume s 100 ~1 by square wave anodic stripping voltammetry has been investigated in detail, using a programmable electronic micropipette. The in situ formation of a mercury film on a glassy carbon electrode substrate, the influence of preconcentration time, injection rate and injected volume of analy...

Mercury is a ubiquitous environmental toxicant which bioaccumulates and has many biological effects, including detrimental effects on the nervous and immune systems. Because mercury can cross the placenta and concentrates in the fetal compartment, the developing fetus is particularly vulnerable. We hypothesize that developmental exposure to mercury will cause immunological changes, leading to a...

RATIONALE Metallic mercury poisoning through intravenous injection is rare, especially for a homicide attempt. Diagnosis and treatment of the disease are challenging. PATIENT CONCERNS A 34-year-old male presented with pyrexia, chill, fatigue, body aches, and pain of the dorsal aspect of right foot. Another case is that of a 29-year-old male who committed suicide by injecting himself metallic ...
