heavy metals entrance to fish body tissues and transferring to human body systems after their consuming makes numerous undesirable effects and health problems. the aim of this study was to determine some heavy metals (lead, cadmium and mercury) in fresh fishes marketed in khorramabad city, west of iran. in this descriptive study, five samples of 17 fish species with high consumption were purcha...

An association between autism and early life exposure to mercury is a hotly debated issue. In this study, 91 autistic Polish children, male and female, 3-4 and 7-9 years old, were compared to 75 age- and sex-matched healthy children with respect to: demographic, perinatal, clinical and developmental measures, parental age, birth order, morphometric measures, vaccination history, and hair mercur...

Portulaca quadrifida Linn. has been evaluated for its hepatoprotective activity in Swiss albino mice using the mercury induced hepatotoxicity. The ethanolic extract showed remarkable activity against mercury-induced hepatotoxicity as judged from biochemical parameters such as serum aspartate amino transferase (AST), alanine amino transferase (ALT), alkaline phosphatase (ALP) and levels of lipid...

Anodic stripping voltammetry (ASV) with rotating glassy carbon electrode (RGCE) and microfiber carbon electrode (μFCE), both filmed with mercury, were used to determine copper content in wine. Influence of phenolics on in situ mercury film formation was studied. Wine and quercetin were added gradually into solution of Hg(II) in acetic acid-sodium acetate buffer (pH = 4.60). Reduction of Hg(II) ...

Total lipids, fatty acid composition and heavy metal content of Sardina pilchardus fillet samples captured in February 2014 in Beni saf, Mostaganem, Ghazaouet, Algiers and Jijet coast were evaluated. Total lipid content was related to the five sites of catch (p < /em>< 0.05). Concerning the heavy metals, the levels of lead (Pb) ranged from 0.013mg to 0.024mg, however those of mercury (Hg) varie...

BACKGROUND Mercury is a global pollutant, and prenatal exposure is associated with adverse health effects. To date, no studies have evaluated the association between prenatal mercury exposure and DNA hydroxymethylation, an epigenetic modification important for tissue differentiation and embryonic development. OBJECTIVES We sought to evaluate the association between prenatal mercury exposure a...

In the presence of metal stress, plants can resort to a series of tolerance mechanisms. Therefore field studies should be undertaken in order to evaluate the real role of these mechanisms in stress coping. The aim of this paper was to clarify the biochemical processes behind mercury tolerance in Halimione portulacoides (L.) Aellen (Caryophyllales: Chenopodiaceae) collected in a mercury contamin...

Mercury is added to the biosphere by anthropogenic activities raising the question of whether changes in the human chromatin, induced by mercury, in a parental generation could allow adaptation of their descendants to mercury. We review the history of Andean mining since pre-Hispanic times in Huancavelica, Peru. Despite the persistent degradation of the biosphere today, no overt signs of mercur...

To measure the hazard to the worker it is often necessary to determine the atmosphere concentration of mercury in a workroom. It should be borne in mind that inhalation of mercury, though probably the most dangerous, is not the only way by which mercury enters the body. It follows that a measurement of the mercury content of the atmosphere does not give a full indication of the hazard. Air anal...
