The aims of this study were to evaluate whether chronic intoxication with mercury chloride (HgCl2), in a low concentration over a long time, can be deposited in the central nervous tissue and to determine if this exposure induces motor and cognitive impairments. Twenty animals were intoxicated for 45 days at a dose of 0.375 mg/kg/day. After this period, the animals underwent a battery of behavi...

Introduction Mercury poisoning causes hearing loss in humans and animals. Acute and long-term exposures produce irreversible peripheral and central auditory system damage, and mercury in its various forms of presentation in the environment is ototoxic. Objective We investigated the otoacoustic emissions responses in a riverside population exposed to environmental mercury by analyzing the inhibi...

Mercury is a widespread environmental contaminant with neurotoxic impacts that have been observed over a range of exposures. In addition, there is increasing evidence that inorganic mercury (iHg) and organic mercury (including methyl mercury) have a range of immunotoxic effects, including immune suppression and induction of autoimmunity. In this study, we investigated the effect of iHg on a mod...

Introduction Mercury poisoning has been recognized for over a century. Evans' (1962) report of poisoning due to chronic exposure to mercury vapour in industry is well known. Polson and Tattersall (1969) have described other circumstances including the ingestion of mercurous and mercuric chlorides, the subcutaneous, intravenous and intra-arterial injection of elemental mercury and acute exposure...

BACKGROUND Dental assistants help the dentist in preparing material for filling teeth. Amalgam was the filling material mostly commonly used in Norway before 1980, and declined to about 5% of all fillings in 2005. Amalgam is usually an alloy of silver, copper, tin and mercury. Copper amalgam, giving particularly high exposure to mercury was used in Norway until 1994. Metallic mercury is neuroto...

Sources of elemental mercury (Hg0) include old natural gas regulators, manometers, sphygmomanometers, thermometers, and thermostats. Causes of Hg0 spills include improper storage, container breakage, children playing with Hg0, the breakage of devices containing Hg0, and ritualistic use of Hg0. Inhalation is the primary exposure route for Hg0. Mercury released into the environment can enter lake...

the purpose of this study was to evaluate the exposure to mercury (hg), and to examine the various parameters, which contribute to high levels of mercury of iranian dentists in tehran. one-hundred hair samples were collected from dentists. in addition, fifty samples from a control group were taken for comparison. the survey included a structured questionnaire designed to provide information abo...

lead poisoning is a historic universal disease. acute or chronic lead exposure may cause reversible or even permanent damages in human beings. environmental lead exposure is a global health concern in children. occupational lead poisoning is still a health issue, particularly in developing countries. during the last decades, new methods and medications have been advocated for the prevention and...
