93 Abstract The findings presented here suggest that mercury poisoning from dental amalgams may play a role in the etiology of oral health disorders in multiple sclerosis (MS) patients. Comparisons between MS subjects with dental amalgams and a control group of MS subjects without amalgams found significantly fewer oral cavity symptoms per subject in the amalgam-removal group during twelve mont...

An analytical method using silica supported silver nanoparticles as a novel sorbent for the enrichment and determination of inorganic mercury (iHg) in surface water samples has been developed. Silver nanoparticles (AgNPs) were synthesized by a completely green procedure and were deposited onto the amine functionalized surface of silica submicrospheres (SiO2-NH2). The prepared nanocomposite mate...

OBJECTIVE To determine the amount of amalgam entering the waste stream during removal of dental amalgam restorations. METHODS Dental amalgam restorations were removed from anatomic replica teeth and natural teeth by means of a tungsten carbide bur, a high-speed handpiece and a conventional suction system. The weight of amalgam particles trapped in the primary and secondary solids separators w...

Objectives: In artisanal small-scale gold mining (ASGM) areas in many developing countries, mercury (Hg) is used to extract gold from ore. Data of 1250 participants from Indonesia, Mongolia, Philippines, Tanzania, and Zimbabwe were combined to analyze the relation between exposure in ASGM areas and body burden. Methods: Four groups were selected relating to their intensity of contact with mercu...

UNLABELLED Parts of the population are permanently exposed to low levels of Hg degrees and Hg(II) from dental amalgam. It was the aim (1) to investigate the internal exposure to amalgam-related mercury from the kinetics of inorganic Hg in plasma and erythrocytes after amalgam removal, and (2) to estimate the amalgam-related absorbed dose. Dietary coexposure was monitored by determination of blo...

Background: Mercury (Hg) is a hazardous metal responsible for environmental contamination and human intoxication. Methyl mercury bio-accumulation through food chain can be responsible for chronic mercury exposure of South Caspian Sea communities with a diet rich in fish. Uncertainties about exposure levels that could have damaging consequences for nervous system development of infants makes b...

We studied exposure to methyl mercury (MeHg) in Swedish pregnant women (total mercury [T-Hg] in hair) and their fetuses (MeHg in cord blood) in relation to fish intake. The women were recruited at antenatal care clinics in late pregnancy to participate in an exposure study of environmental pollutants. Fish consumption was evaluated using food frequency questionnaires including detailed question...

A flow injection analysis (FIA) incorporating a thiosemicarbazone-based coated wire electrode (CWE) was developed method for the determination of mercury(II). A 0.1 M KNO(3) carrier stream with pH between 1 and 5 and flow rate of 1 mL·min(-1) were used as optimum parameters. A linear plot within the concentration range of 5 × 10(-6)–0.1 M Hg(II), slope of 27.8 ± 1 mV per decade and correlation ...

Mercury is found in the environment as elemental mercury, inorganic mercury or organic mercury (ethyl-, methyl-, alkyl-, or phenylmercury). In our environment it is present in thermometers, thermostats, dental amalgams, paint, cosmetic products, laxatives, diuretics and antiseptics. Organic mercury is the most toxic and most frequent form of mercury exposure, found in fish, poultry, pesticides ...
