A 24-year-old girl injected approximately I ml of elemental mercury from a few broken thermometers to her right cubital fossa. It led to the formation of a tumoral lesion which was erythematous, lobulated, painful, with secretory sinuses in the injected area. Biopsy showed foreign body granulomas with metallic mercury that appeared as dark opaque globules. X-rays showed metallic densities i...

The adult nephrotic syndrome as met with in Nairobi is predominantly encountered in young sophisticated African women, most of whom began to use skin-lightening creams containing mercury before the symptomatic onset of their illness. The particular form of mercury involved is well known to cause the nephrotic syndrome in other circumstances-for example, when applied to the skin in the treatment...

background: contamination of water by toxic chemicals has become commonly recognized as an environmental concern. based on our clinical observation in mashhad, northeastern iran, many people might be at risk of exposure to high concentrations of toxic heavy metals in water. because wastewater effluents as well as water wells have been commonly used for irrigation over the past decades, there ha...

BACKGROUND: Public laws regulating dredged material disposal (Section 404 of the Clean Water Act and Section 103 of the Ocean Dumping Act) require ecological evaluation prior to the permitting of operations. Assessment of the potential for bioaccumulation of chemical contaminants in sediment, including heavy metals, is required as part of the evaluation process. Metals can represent significant...

The quality of water in different usages especially drinking water has an important role on human health. As increasing the urban population and developing the industries, the releasing different materials into water cause various pollutions and problems for human cycles. The important goal of the present study is analyzing the mercury existence and pollution on different part of urban built en...

due to increasing worldwide water pollution, fish might be a source of excessive zinc, mercury, arsenic or  manganese  intake. the  aim  of  this  study  was  to  evaluate if  fish atopy/sensitization and fish consumption behavior are associated with eczema severity and blood levels of the 4 heavy metals. one-hundred and nineteen patients with eczema and 43 patients with miscellaneous non-eczem...

Mercury (Hg) causes hazardous cumulative effects in humans; like central nervous system disorders,hypertension and chromosomal aberrations. Therefore, due to high toxicity and bioaccumulationfactor, mercury determination and speciation in human blood is very important. A sensitive,accurate, precise and inexpensive method was demonstrated for preconcentration and speciationof ultra-trace mercury...

Mercury detection in water has attracted a lot of research interest due to its highly toxic nature and adverse environmental impact. In particular, the recent discovery of specific binding of Hg(II) to thymine-rich (T-rich) DNA resulting in T-Hg(II)-T base pairs has led to the development of a number of sensors with different signaling mechanisms. However, the majority of such sensors were non-...

The causes of autoimmune responses leading to human kidney pathology remain unknown. However, environmental agents such as microorganisms and/or xenobiotics are good candidates for that role. Metals, either present in the environment or administered for therapeutic reasons, are prototypical xenobiotics that cause decreases or enhancements of immune responses. In particular, exposure to gold and...
