Due to hygienic risks of mercury residues in food and marine originated supplements, measuring total mercury and methyl mercury contents of canned tuna as a highly consumable marine food product is essential. In this study, 40 canned Tuna fish (from Persian Gulf) were collected in 2015 and then flame atomic absorption spectrometer (FAAS) and thermo gas chromatography mass spectrophotometry were...
occupational exposure to elemental mercury vapor usually occurs through inhalation during its utilizations. this leads to a variety of adverse health effects. in some islamic cities, this type of poisoning may occur during gilding of shrines using elemental mercury with gold. herein, we report on three male patients aged 20–53 years, who were diagnosed with occupational metallic mercury poisoni...

With the growth and development of chemical plants, the amount of mercury released in wastewater has increased. Mercury in wastewater contains harmful compounds which are hazardous to the human health and living organisms. Therefore, its removal from wastewater is significant. There are various techniques or methods available for removing mercury from aqueous solutions. This study focused upon ...

Background and Objective: Information about the history of exposed individuals to mercury and monitoring mercury levels in body can be obtained by analyzing the longitudinal section of hair. The aim of this study was to analyze changes of mercury concentrations in hair length and daily mercury intake in women living in Bandar Abbas, Bushehr and Mahshahr cities. Materials and Methods: In this c...
Background: Dental amalgam, a mixture of approximately 50% mercury with silver, tin, zinc and copper in varying ratios, is a major source of mercury pollution in the general population not occupationally exposed. The toxicity of mercury is enhanced because it is so readily absorbed, with around 90-100% of mercury vapor being absorbed through the oral mucosa. The aim of the current study is to e...
بررسی مقایسه ای کارایی نانو لوله های کربنی چند جداره و تک جداره در جذب و نمونه برداری از بخارات جیوه
Background and aims: Sampling of toxic mercury vapors (Hg0) is necessary for determination of occupational exposure levels of workers exposed to this contaminant. Given the tendency of carbon nanotubes for mercury adsorption, carbon nanotubes can be expected to be suitable sampling media for mercury. The aim of this study was to compare the performance of multi-walled and single-walled carbon n...
Background: Dental clinics are known to be one of the largest users of Toxic inorganic mercury. It is well documented that dentists and dental assistants who work with amalgam are chronically exposed to mercury vapor. This study investigates exposure to mercury vapor in a dental clinic. Methods: GBC cold vapor atomic absorption spectrometry (AAS), using sodium borohydride as the reducing age...
