Hydrogen sulfide: UK occupational exposure limits.
Hydrogen sulfide (H2S) is a toxic gas with an offensive odour reminiscent of rotten eggs. There is the potential for widespread occupational exposure to H2S, including in the oil and water treatment industries. There is a particular concern for exposure in confined spaces such as manholes and sewer pipes; the high concentrations that can build up in such conditions (> 1000 parts per million (pp...
متن کاملSensory and Cognitive Effects of Acute Exposure to Hydrogen Sulfide
BACKGROUND Some epidemiologic studies have reported compromised cognitive and sensory performance among individuals exposed to low concentrations of hydrogen sulfide (H2S). OBJECTIVES We hypothesized a dose-response increase in symptom severity and reduction in sensory and cognitive performance in response to controlled H2S exposures. METHODS In separate exposure sessions administered in ra...
متن کاملHydrogen sulfide exposure in an adult male
Hydrogen sulfide (H(2)S) is responsible for many incidents of occupational toxic exposure, especially in the petroleum industry. The clinical effects of H(2)S depend on its concentration and the duration of exposure. H(2)S is immediately fatal when concentrations are over 500-1000 parts per million (ppm) but exposure to lower concentrations, such as 10-500 ppm, can cause various respiratory sym...
متن کاملHealth effects from chronic low-level exposure to hydrogen sulfide.
The acute toxic effects of hydrogen sulfide have been known for decades. However, studies investigating the adverse health effects from chronic, low-level exposure to this chemical are limited. In this study, the authors compared symptoms of adverse health effects, reported by residents of two communities exposed mainly to chronic, low-levels of industrial sources of hydrogen sulfide, to health...
متن کاملeffects of long-term exposure to hydrogen sulfide on human red blood cells
background: hydrogen sulfide (h 2 s) exhibits both physiological and toxicological roles in the biological systems. acute exposure to high levels of h 2 s is life threatening while long-term exposure to ambient levels of h 2 s elicits human health effects. objective: to study the harmful effects of long-term exposure to low levels of h 2 s on human blood cells. methods: 110 adult workers from i...
