An unrecognised form of hydrogen sulphide keratoconjunctivitis.
In 1988 six men were referred to St Paul's Eye Hospital after the onset of acutely painful, red eyes while at work at a local sausage casing factory. These patients prepared sheep intestine for sausage skin manufacture. Ocular examination showed bilateral blepharospasm, photophobia and lacrimation, intense conjunctival injection, and superficial punctate corneal erosions. There were no other ab...
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...
متن کاملThe Sulphidation of Calcined Limestone with Hydrogen Sulphide and Carbonyl Sulphide
-The sulphidation of calcined limestone with H2S , COS and mixtures of H2S and COS was studied in a thermogravimetric analyzer at temperatures between 500 and 700°C. The applied H2Sand COS-pressures corresponded with those in coal gas produced by modern coal gasifiers, i.e. 50-12,000 Pa for H2S and 50-1000 Pa for COS. The reaction orders in H2S and COS as well as the activation energies of the ...
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...
