Through 1996 into 1997, a spot investigation on mercury contamination was conducted three times in Tanzania, especially around the Lake Victoria. A total of 150 goldminers, 103 fishermen and their families, and 19 residents of Mwanza City volunteered for the current study. A high total mercury level of 48.3 ppm (near to 50 ppm, a critical level of Minamata disease) and over in the head hair was...

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...

Abstract. The paper presents a case study of mercury in two types paleoarchives: ice cores and prehistoric animal hair, to assess the potential Hg using as proxy for environmental climate changes. Belukha core is well-suitable reconstruction short-term long-term deposition, recording global regional, natural anthropogenic emissions well regional changes during 320 years. concentrations hair mam...

Mercury toxicity is highly correlated with hypertension, coronary heart disease (CHD), myocardial infarction (MI), stroke and other cardiovascular disease. Mercury has a high affinity for sulfhydryl (-SH) groups, which inactivates numerous enzymatic reactions, amino acids, and sulfur-containing antioxidants [NAC (n-acetyl cysteine, ALA (alpha lipoic acid), GSH (glutathione)], with subsequent de...

OBJECTIVES Gold miners use mercury to extract gold from ore adding liquid mercury to the milled gold-containing ore. This results in a mercury-gold compound, called amalgam. Miners smelt this amalgam to obtain gold, vaporizing it and finally inhaling the toxic mercury fumes. The objective was to merge and analyze data from different projects, to identify typical signs and symptoms of chronic in...

Clarkson and Magos (2006) provide their perspectives on the toxicology of mercury vapor and dental amalgam. As scientists who are involved in preparing a German federal guideline regarding dental amalgam, we welcome additional scientific data on this issue. However, Clarkson and Magos do not present all the relevant studies in their review. The additional data provided here show that: (a) Denta...

BACKGROUND High levels of mercury in the Cree population of James Bay, Que., have been a cause of concern for several years. This study examines changes in mercury levels within the Cree population between 1988 and 1993/94 and identifies potential determinants of high mercury levels. METHODS Data on mercury levels among the Cree were obtained through a surveillance program undertaken by the C...

Pediculosis seems to have afflicted humans since the most ancient times and lice have been found in several ancient human remains. Examination of the head hair and pubic hair of the artificial mummy of Ferdinand II of Aragon (1467-1496), King of Naples, revealed a double infestation with two different species of lice, Pediculus capitis, the head louse, and Pthirus pubis, the pubic louse. The ha...
