Total mercury levels were measured in largemouth bass (Micropterus salmoides), "sunfish" (Lepomis spp.), and "catfish" (primarily Ameiurus spp. and Ictalurus punctatus) from 1971 to 2004 in the middle Savannah River (river km 191 to 302), which drains the coastal plain of the southeastern U.S. Total mercury concentrations were higher in largemouth bass (overall mean of 0.55 mg/kg from 1971 to 2...

Effects of Mercury Vapour Exposure at Low Concentrations on Urinary Activity of N-AcetylBeta-D-Glucosaminidase: Nobuo IS H I H A R A. Research Centre for Occupational Disease, Tohoku Rosai Hospital—Effects of exposure to mercury vapour less than 0.02 mg Hg/m3 on urinary N-Acetylbeta-D-glucosaminidase (NAG) activity were studied in seven Japanese workers from 1991 to 1997. According to the recor...

INTRODUCTION Small-scale gold miners in Ghana have been using mercury to amalgamate gold for many years. Mercury is toxic even at low concentration. We assessed occupational exposure of small-scale gold miners to mercury in Prestea, a gold mining town in Ghana. METHODS We conducted a cross-sectional study in which we collected morning urine samples from 343 small-scale gold miners and tested ...

Mercury distribution in the oceans is controlled by complex biogeochemical cycles, resulting in retention of trace amounts of this metal in plants and animals. Inter- and intra-specific variations in mercury levels of predatory pelagic fish have been previously linked to size, age, trophic position, physical and chemical environmental parameters, and location of capture; however, considerable v...

Protective potential of propolis was evaluated against mercury induced oxidative stress and antioxidant enzymatic alterations in mice liver. Exposure to mercuric chloride (HgCl2; 5 mg/kg; ip) induced oxidative stress by increasing lipid peroxidation and oxidized glutathione level along with concomitant decrease in glutathione and various antioxidant enzymes. Mercury intoxication deviated the ac...

Mercury is a highly potent cell toxin with effects on human and animal nervous systems. Mercury vapour released from dental amalgam is the predominant source of mercury in the human adult and foetal central nervous system in populations of developed countries. Only in small populations with high consumption of methyl mercury containing fish can the contribution from fish consumption reach or su...

BACKGROUND Mercury is a toxic metal with its effects on human health ranging from acute to chronic in a very short time of exposure. Artisanal and small-scale gold mining (ASGM) is the main source of direct human exposure to mercury. AIM To access the effect of mercury exposure on the renal function and level of personal protective equipment (PPE) compliance among small-scale gold miners in B...

Global mercury emission inventories include anthropogenic emissions, contributing via current use or presence of mercury in a variety of products and processes, as well as natural source emissions. These inventories neglect the contribution of areas contaminated with mercury from historical accumulation, which surround mines or production plants associated with mercury production or use. Althou...

OBJECTIVE The objective of this study is to evaluate the awareness of patients with dental fillings about the toxicity of mercury in dental amalgam. MATERIALS AND METHODS Adult patients having at least one amalgam filling in their mouth were recruited in the Oral Diagnosis Department of OAUTHC, Ile-Ife Dental Hospital. Participants were recruited consecutively as they report in the clinic. Da...
