Background and Aim: Amalgam is used in dentistry cautiously, due to the toxicity of mercury in dental amalgam. Dentists are exposed to mercury vapor in their routine occupational practice, which can be harmful to their health. The aim of the present study was to measure urinary mercury concentrations in general dentists and restorative specialists in Mashhad in 2010. Materials and Methods: This...
Background and purpose: Mercury contamination is still a threat to the environmental and public health in both developed and developing countries. The aim of this study was to determine the total and organic mercury content in the muscle of goldfish (Carassius aurathus gibelio) obtained from the east and west of Anzali Wetland. We also assessed the health risks involved in consumption of this f...
Mercury is a toxic and non-essential metal in the human body. Mercury is ubiquitously distributed in the environment, present in natural products, and exists extensively in items encountered in daily life. There are three forms of mercury, i.e., elemental (or metallic) mercury, inorganic mercury compounds, and organic mercury compounds. This review examines the toxicity of elemental mercury and...
Abstract In the basin of western China, four different kinds lithological reservoirs are developed, including low-permeability sandstone, sedimentary tuff, shale and volcanic rock. There is generally a large difference in micropore structure characteristics distribution laws due to reservoirs. The reserving capacity as well porous flowability, mechanism determined by hydrocarbon Low-temperature...
Content of mercury in hepatopancreas, muscle and exoskeleton of blue crab T. prymna from Musa estuary and their relationship with size of the organism and season were determined. Mean concentration of mercury in hepatopancreas, muscle and exoskeleton were 1.23, 0.61 and 0.41 µg/g dw, respectively. There was significant difference (p<0.05) in mercury levels depending on the sex with greater ...
From a public health perspective, there is growing concern about dietary mercury intake as the most important source of mercury exposure. This study was performed to estimate dietary mercury exposure and to analyze the association between mercury intake and blood mercury levels in Koreans. The study subjects were 553 adults, comprising a 10% representative subsample of the Korean National Envir...
An automatic microgravimetric screening system based on piezoelectric detection and the use of acidic stannous chloride as reductant was developed for the fast detection and determination of total mercury in water. Reduced mercury is detected as an amalgam by using a gold-coated piezoelectric crystal, the sensor subsequently being regenerated by passing it through a peroxydisulfate solution. Th...
Air pollution control devices (APCDs) are installed at coal-fired power plants for air pollutant regulation. Selective catalytic reduction (SCR) and wet flue gas desulfurization (FGD) systems have the co-benefits of air pollutant and mercury removal. Configuration and operational conditions of APCDs and mercury speciation affect mercury removal efficiently at coal-fired utilities. The Ontario H...
This study examined the relationship between mercury content and mercury evaporation from amalgams during setting. Two different types of commercial high-copper amalgams (single composition and admixed types) were used. Cylindrical specimens of each amalgam were prepared with five different mercury contents according to ADA Specification No.1. Specimens were also prepared by hand condensation. ...
Background: Mercury in any form is poisonous and mercury toxicity most commonly affects the nervous, gastrointestinal (GI) and urinary systems. The aim of this study was to investigate the specific effect associated with mercury toxicity and to evaluate the effectiveness of iron and vitamin B6 supplement on mercury-induced toxicities in rats. Methods: This experiment was performed on 25 rats...
