Passive Sampling of Inorganic Mercury Vapor by Charcoal Tube

Haemodialysis and charcoal haemoperfusion in acute inorganic mercury poisoning.

A 29-year-old gardener developed acute renal failure following the ingestion of 'Mersil', a combination of mercurous and mercuric chloride, achieving a plasma mercury concentration of 22,000 nmol/litre (400 micrograms/litre). Haemodialysis and charcoal haemoperfusion were ineffective in removing mercury despite prior treatment with the chelating agent dimercaprol. The acute renal failure resolv...

Comparison Between a Passive Organic Vapor Monitor (OVM) and a Charcoal Tube for Monitoring Benzene, Ethyl Benzene, Toluene and Xylene

Introduction Due to increased awareness of the toxicity of organic substances, government organization, such as the Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH), have continually decreased the permissible exposure limits of many organic substances. For example, in the last ten years, the permissible exposure limit for...

Modified determination of total and inorganic mercury in urine by cold vapor atomic absorption sectrometry.

In this procedure a single-beam spectrophotometer is used without background correction. By the method of Magos [Analyst (London) 96, 847 (1971)] mercury in undigested urine is complexed to L-cysteine in acid solution. At high pH and in the presence of stannous ions, mercury ions are reduced to elemental mercury. The mercury vapor is partitioned above the reagent solution in a specially designe...

Organic and Inorganic Mercury in Neonatal Rat Brain after Prenatal Exposure to Methylmercury and Mercury Vapor

BACKGROUND Many populations are exposed to multiple species of mercury (Hg), predominantly organic Hg as methylmercury (MeHg) from fish, and inorganic Hg as Hg vapor from dental amalgams. Most of our knowledge of the neurotoxicity of Hg is based on research devoted to studying only one form at a time, mostly MeHg. OBJECTIVES In this study we investigated the effects of prenatal exposure to Me...
