Environmental contamination has exposed humans to various metal agents, including mercury. It has been determined that mercury is not only harmful to the health of vulnerable populations such as pregnant women and children, but is also toxic to ordinary adults in various ways. For many years, mercury was used in a wide variety of human activities. Nowadays, the exposure to this metal from both ...

Heavy metals such as mercury, cadmium and copper are known to be extremely toxic to organisms. Mercury has been recognized as an environmental contaminant since the Minamata disaster in the late 1950s. Minamata disease which was caused by the consumption of marine fishes severely polluted with mercury from local industrial discharge due to this Minamata disaster (Takeuchi et al., 1978; Takeuchi...

in this study mercury was determined in canned tuna fish produced and distributed in iran after digestion by the standard methods of aoac. mercury contents in fish and canned tuna fish were determined by cold vapor atomic absorption spectrophotometry. the metal contents expressed in mg/kg wet weight for mercury varied from 0.017 to 0.394 (average of 0. 089) and 0.023 to 0.529 (average of 0.146)...

consequences of mercury exposure were recognized from prehistory to the present. The first emperor of unified China who came to power in 221 B.C., Qin Shi Huang, reportedly died of ingesting mercury pills that were intended to give him eternal life. The severity of mercury's toxic effects depends on the form and concentration of mercury and the route of exposure. Although its potential for toxi...

background: mercury is a heavy metal with high toxic effects. it has many apply to various industries, so can enter to the environment from different resources. therefore, its elimination from wastewater is a major challenge. in this study, removal of mercury from aqueous solution using two types of almond shell was investigated and compared. methods: this experimental-intervention study has be...

mercury is among the most toxic nonradioactive elements which may cause toxicity even at low doses. some studies showed release of mercury from dental amalgam fillings in individuals who used mobile phone. this study was conducted to assess the effect of high-field mri on mercury release from dental amalgam filling. we studied two groups of students with identical tooth decays requiring a simil...

Mercury is a toxic heavy metal which is widely dispersed in nature. Most human exposure results from fish consumption or dental amalgam. Mercury occurs in several chemical forms, with complex pharmacokinetics. Mercury is capable of inducing a wide range of clinical presentations. Diagnosis of mercury toxicity can be challenging but can be obtained with reasonable reliability. Effective therapie...

Methylmercury is a toxic substance which accumulates in fish and other biota and causes toxicological problems when consumed by humans. Certain mercury resistant bacteria are able to convert the highly toxic methylmercury to a much less toxic form. Several mer operons, a group of genes which encode this function, have been cloned and characterized. However, they have been isolated and cloned fr...

Mercury exposure is the second-most common cause of toxic metal poisoning. Public health concern over mercury exposure, due to contamination of fish with methylmercury and the elemental mercury content of dental amalgams, has long been a topic of political and medical debate. Although the toxicology of mercury is complex, there is evidence for antioxidant protection in the prevention of neurolo...
