Organic mercury (Hg) species exert their toxicity primarily in the central nervous system. The food relevant Hg species methylmercury (MeHg) has been frequently studied regarding its neurotoxic effects in vitro and in vivo. Neurotoxicity of thiomersal, which is used as a preservative in medical preparations, is to date less characterised. Due to dealkylation of organic Hg or oxidation of elemen...

BACKGROUND AND OBJECTIVE Mercury pollution is one of the most pressing environmental problems. Therefore, the impact of mercury on human body, the nervous system in particular, remains topical. The aim of the study was to identify the morphological characteristics of neurons and neuroglia in spinal ganglia of rats receiving antioxidants in the presence of small doses of mercury (II) chloride. ...

BACKGROUND With increases in globalization, cultural remedies from Chinese, Ayurvedic, Arab and other traditions have become more available to international consumers, offering unfamiliar "Natural Health Products" (NHP), used as alternative medicine or supplementary medicine. Contamination with toxic ingredients including lead, mercury, arsenic, and other toxic elements has been documented in s...

FT-IR spectra of liver tissue isolated from mice, Mus musculus, have been recorded in the region of 4000 – 400 cm-1 for normal, mercury treated and recovery phase. In this study, the total protein content was found to be decreased in the liver tissues after treatment with median-lethal dose of mercuric chloride. The marked fall in the level of bio-chemical constituent in the tissue due to metal...

The aim of this study is to present data concerning hazardous waste management in the health area, with emphasis to the utilization of mercury in dentistry. The study was based on a bibliographic review regarding the use of mercury in dental fillings and its potential toxicological risks for patients and due to occupational exposure. The studies also take into consideration national and interna...

Seafood is an important source of nutrients for fetal neurodevelopment. Most individuals are exposed to the toxic element mercury through seafood. Due to the neurotoxic effects of mercury, United States government agencies recommend no more than 340g (12oz) per week of seafood consumption during pregnancy. However, recent studies have shown that selenium, also abundant in seafood, can have prot...

We analyzed data from states that participated in the Hazardous Substances Emergency Events Surveillance (HSEES) system maintained by the Agency for Toxic Substances and Disease Registry to describe the public health consequences of mercury releases. From 1993 through 1998, HSEES captured 406 events in which mercury was the only substance released. Schools and universities, private residences, ...

Mercury is an extremely toxic chemical pollutant of our environment. It has attracted the world's attention due to its high mobility and the ease with which it accumulates in organisms. Sensitive devices and methods specific for detecting mercury ions are, hence, in great need. Here, we have integrated a DNA strand displacement reaction with a whispering gallery mode (WGM) sensor for demonstrat...

Nickel and mercury are naturally occurring, highly toxic environmental pollutant. The goal of the present study was investigate the effects of nickel and mercury exposure on the biochemical contents of the muscles tissues of fish Lates calcarifer by using Fourier transform infrared (FT-IR) spectroscopy. FT-IR spectra reveal significant differences in absorbance intensities between the control. ...
