Emf and mercury

Gh Mortazavi, S A R Mortazavi, A R Mehdizadeh
A large body of evidence now indicates that the amount of mercury released from dental amalgam fillings can be significantly accelerated by exposure to radiofrequency electromagnetic fields (RF-EMFs) such as common mobile phones and magnetic resonance imaging (MRI). Studies performed on the increased microleakage of dental amalgam restorations after exposure to RF-EMFs have further supported these findings. Although the accelerated microleakage induced by RF-EMFs is clinically significant, the entire mechanisms of this phenomenon are not clearly understood...

In their paper that is published in Toxicology in Vitro, Rachmawati et al. have recently claimed that in spite of the growing concern about the safety of amalgam, negative reports about the health effects of dental amalgam are still scarce or controversial. Substantial evidence indicates that mercury release from dental amalgam fillings may adversely affect human health. Over the past years, we have shown that exposure to electromagnetic fields (EMFs) can increase the release of mercury from dental amalgam fillings...

BACKGROUND: Makaradhwaja is one of the most potent herbomineral medicines of Ayurveda. Different references for the preparation of Makaradhwaja were reported in classics. According to the proportion of sulfur (Gandhaka), three references were mentioned in classics that is, Dwiguna (2:1 = S: Hg), Triguna (3:1 = S: Hg) and Shadguna (6:1 = S: Hg). Makaradhwaja is prepared by Kupipakwa system of heating. In the preparation of Kupipakwa medicine as the ratio of sulfur to mercury increases it becomes difficult to prepare medicine...

INTRODUCTION: Rasasindura (RS) is one of the unique mercurial preparations commonly used in Ayurveda therapeutics. The traditional procedure followed for preparing RS in the classical furnace has several drawbacks, such as difficulty in controlling temperature, consumption of large quantity of fuel, and excess human effort. AIMS #ENTITYSTARTX00026; OBJECTIVE: The present study was conducted to evaluate an alternate method to prepare RS by using an electrical muffle furnace (EMF) and to standardize this method...

Mercuric ions in water samples were determined by a new modified carbon paste electrode based on N,N'-bis(salicylaldehyde)-phenylenediamine (salophen) as a chemical modifier. The construction, performance, and applications of mercury carbon paste electrode are described. The electrode displays a linear log[Hg(2+)] versus EMF response over a wide concentration range of 3.2 x 10(-7) to 3.2 x 10(-4) with Nernstian slope of 58.8+/-0.3 mV/decade with limit of detection 1.5 x 10(-7) over the pH range 3.8-7.8; the presence of the complex Hg(OH)(+) ion explains the slope of the response curve...

A new ion-selective PVC membrane electrode based on salicylaldehyde thiosemicarbazone as an ionophore is developed successfully as sensor for mercury(II) ions. The electrode shows excellent potentiometric response characteristics and displays a linear log[Hg(2+)] versus EMF response over a wide concentration range of 1.778x10(-6)-1.0x10(-1) M with Nernstian slope of 29 mV per decade with the detection limit of 1.0x10(-6) M. The response time of the electrode is less than 30 s and the membrane electrode operates well in the pH range of 1...

A new heterogeneous precipitate of an organic-inorganic composite cation-exchanger poly-o-toluidine Zr(IV) phosphate was utilized for the preparation of a Hg(II) ion-sensitive membrane electrode for the determination of Hg(II) ions in real aqueous as well as in real samples. The electrode showed good potentiometric response characteristics, and displayed a linear log[Hg(2+)] versus EMF response over a wide concentration range of 1 x 10(-1) - 1 x 10(-6) M with a Nernstian slope of 30 mV per decade change in concentration with a detection limit of 1 x 10(-6)...

The formal redox potential of the Ti(IV, III) couple has been determined at 25 degrees C in 1 M HCl, 2 M NaCl aqueous medium, by emf measurements of a junction-free cell with glass and mercury electrodes. Ti(III) and Ti(IV) concentrations were changed by controlled electrolysis. The mean value of the searched formal potential, in a large range of total titanium concentration, is 9 +/- 1 mV against the molar hydrogen electrode in the same ionic medium.

The objective of this study was to investigate whether exposure of human monocytes to a pulsed ultra-wideband electromagnetic field (EMF) of 1 kV/cm average peak power triggers a signaling pathway responsible for the transcriptional regulation of NFKB (NF-kappaB)-dependent gene expression. Human Mono Mac 6 (MM6) cells were exposed intermittently to EMF pulses for a total of 90 min. The pulse width was 0.79+/-0.01 ns and the pulse repetition rate was 250 pps. The temperature of the medium was maintained at 37 degrees C in both sham- and EMF-exposed flasks...

A new PVC membrane mercury(II) ion electrode based on N,N-dimethylformamide-salicylacylhydrazone (DMFAS) as an ionophore is described, which shows excellent potentiometric response characteristics and displays a linear log[Hg(2+)] versus EMF response over a wide concentration range between 6.2 x 10(-7) and 8.0 x 10(-2) M with a Nerstian slope of 29.6 mV per decade and a detection limit of 5.0 x 10(-7) M. The response time for the electrode is less than 30 s and the electrode can be used for more than 2 months with less than a 2 mV observed divergence in a potentials...

Static electrification of a solid oxide, say a semiconducting oxide in liquid metal, is mainly due to electron transfer between two phases. Excess electrons in the liquid metal phase provided by the oxide give rise to an electrical double layer at the interface. The electrical double layer may be divided into three parts, an immobile inner layer, a compressed diffuse layer, and a flat layer extending into the bulk liquid metal. Differential potential analysis and the induced emf method were used to measure the potential of the compressed diffuse layer and the excess electron density of the flat layer, respectively...

The effects, on normal human subjects, of 3 minutes exposure to electro-magnetic fields (EMFs) emitted from: A) personal computers, B) color television sets, or C) microwave-ovens, or cellular phones were compared by placing the same large sheet of aluminum foil with a square hole or rectangular band-shaped hole at the chest level (or at the side of the head with the cellular phone), with or without grounding the aluminum foil, using the Bi-Digital O-Ring Test Dysfunction Localization and Molecular Identification Methods with cancer related substances (i...

The complex formation of thiomalic acid (H3L) with Hg(II) and Pb(II) was investigated under physiological conditions of 37 degrees C and 0.15 mol dm-3 NaCl by potentiometric titrations using glass electrodes. From the analysis of the emf data in the two systems by use of computer program MIQUV it was concluded that the species formed in the two systems are [HgH4L2], [HgH3L]-, [HgH2L2]2-, [HgHL2]3-, [HgHL], [HgL]-, [HgL2]4-, [Hg(OH)L]2-, [Hg(OH)L2]5-, [PbH2L2]2-, [PbH2L]+, [PbHL2]3-, [PbHL], [PbL]-, [Pb(OH)L]2-, and [Pb(OH)2L]3-...

Unsuspected prolonged exposure to abnormal environmental (very high frequency) electro-magnetic fields (EMF), electric fields (EF) or magnetic fields (MF) at 60 Hz or 16K Hz in the bedroom or workplace may contribute to the development of various intractable medical problems. Most of the clinical symptoms appear when the individuals are exposed to EMF for many hours a day for at least several months to 1-year for relatively benign diseases or symptoms (such as intractable pain or medical problems), or several to over 10 years for more serious diseases (such as cancers of the digestive system or other organs), all of which seem to appear with the additional co-existence of micro-circulatory disturbances with Thromboxane B2 (TXB2), bacterial or viral infections and decrease or absence of acetylcholine, and lead, mercury, or aluminum deposits, with or without asbestos...
