Exposure to hydrogen sulphide and respiratory function.
A study was carried out to assess possible effects of low concentrations of hydrogen sulphide on respiratory function. The cohort comprised 26 male pulp mill workers (mean age 40.3, range 22-60 years) with a daily exposure to hydrogen sulphide in the workplace, and 10 volunteers, who had asthma (three men, mean age 40.7, range 33 to 50 years, and seven women, mean age 44.1, range 31 to 61 years...
متن کاملHydrogen sulphide exposure in waste water treatment
Background The aims of this study was to assess exposure to hydrogen sulphide (H2S) among waste water treatment workers (WWWs), and achieve a better measure of the risks of H2S exposure than only using the eight-hour average value and the ceiling value because the exposure pattern of H2S for WWWs is dominated by short-term peaks. Methods Ninety-three measurements of H2S from 56 WWWs in three ...
متن کاملOccupational exposure to carbon dioxide, ammonia and hydrogen sulphide on livestock farms in north-west Spain.
The influence of the type of farming on harmful gas exposures to carbon dioxide (CO(2)), ammonia (NH(3)) and hydrogen sulfide (H(2)S) was assessed from the perspective of animal welfare and occupational hygiene. Summer data of H(2)S, NH(3) and CO(2) concentrations and of environmental parameters were collected from 31 farms. The indices of exposure for long-term exposures to NH3 suggest the low...
متن کاملBiochemical adaptations of four submerged macrophytes under combined exposure to hypoxia and hydrogen sulphide
A hydroponic experiment was performed to investigate the stress responses and biochemical adaptations of four submerged macrophytes, Potamogeton crispus, Myriophyllum spicatum, Egeria densa, and Potamogeton oxyphyllus, to the combined exposure of hypoxia and hydrogen sulfide (H2S, provided by NaHS). The investigated plants were subjected to a control, hypoxia, 0.1mM NaHS, 0.5 mM NaHS, 0.1 mM Na...
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...
