Determination of mercury in the urine by atomic absorption spectrometry - cold vapor technique
Urine is a liquid waste product of the body. Substances that are ingested and fail to be apsorbed are excreted, solid waste through the intestines, the urine through the kidney and ureter and another fluid from the body through perspiration. Determination of mercury content of urine is not included in routine examinations, but mercury can be present in urine at concentrations that could have se...
متن کاملDetermination of mercury concentration in the air of dental clinics and the urines of their personnel with cold vapor atomic absorption spectrometry
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...
متن کاملDetermination of Mercury in Blood and Urine by Cold Vapor AAS Using the VGA-77 Authors
A variety of clinical manifestations of mercury intoxication may be encountered depending mainly upon the mercurial involved. Inhalation of elemental mercury results in pulmonary, central nervous system (CNS) and kidney damage. The CNS damage produces a spectrum of behavioural and neurological deficits. Ingestion of inorganic mercurials may, because of their corrosive nature, produce devastatin...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
A sequential injection cold-vapor atomic absorption method for the determination of total mercury.
A sequential injection (SI) method for the determination of mercury via cold vapor atomic absorption spectrophotometry is presented. The method differs from flow injection (FI) cold vapor methods for the determination of mercury because of the simplicity of the system required for the method: one pump, one valve, a gas-liquid separator, and an atomic absorption spectrophotometer equipped with a...
