Hydrogen sulphide poisoning: blood sulphide concentration and changes in haem metabolism.
Hydrogen sulphide is still a potential hazard in several occupations"2 and especially in sulphate pulp mills (P Jappinen, academic dissertation) and oil refineries. Blood sulphide may be used as an indicator of an excessive human hydrogen sulphide exposure. Fatal hydrogen sulphide concentrations are known.34 Blood sulphide concentrations have been determined before by ion selective electrodes c...
متن کاملFatal hydrogen sulphide poisoning in unconfined spaces.
Fatal hydrogen sulphide poisoning usually occurs in confined spaces. We report two fatal accidents in unconfined spaces. The first accident caused the death of three workers who entered an unconfined room in a silo of sludge at the same time that a truck dumped several tons of sludge from water purification stations. The hydrogen sulphide that had accumulated inside the silo spilled out into th...
متن کاملPersistent cognitive and motor deficits following acute hydrogen sulphide poisoning.
This case study describes the long-term after-effects of hydrogen sulphide exposure in a previously health 27-year-old male. Upon hospital admission the patient had a Glasgow Coma Score (CGS) of 3; with emergency treatment including hyperbaric oxygen treatments, he progressed to a GCS of 15 on day 7. Although both CT and MRI scans were unremarkable, PET using F-18 deoxyglucose administered 3 ye...
متن کاملOutcome after hydrogen sulphide intoxication.
AIM Hydrogen sulphide (H2S) intoxication in man is frequently associated with a fatal outcome. In small animal models hydrogen sulphide has demonstrated profound protection against hypoxia. No reports that focus on a potential protective effect in humans have been published. METHODS The frequency and outcome of a large cohort of hydrogen sulphide intoxications is described. RESULTS From 198...
متن کاملHydrogen sulphide production by bacteria.
Hydrogen sulphide production by growing cultures and non-multiplying suspensions was compared and the factors influencing the sensitivity of the tests were investigated. Cysteine hydrochloride (0.01 yo) was added to Lemco broth to provide a medium with a standard source of sulphur. H,S was detected with lead acetate papers more readily than by lead acetate agar. Suspensions were tested with cys...
