Hydrogen sulfide: UK occupational exposure limits.

Hydrogen 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...

Investigation of hydrogen sulfide adsorption in metallic scaffold MOF-5 nanocomposite based on activated carbon for the use of respiratory mask cartridge

Introduction: Hydrogen sulfide is one of the most important impurities in natural gas. Due to the fact that this gas is hazardous, toxic, corrosive and volatile, therefore, the removal of hydrogen sulfide has been studied using several methods. One of the most known procedures is the adsorption process. In the present study, activated carbon and activated carbon-based composite scaffolds (MOF-5...

Recommendation of the Scientific Committee on Occupational Exposure Limits for Hydrogen peroxide

Effects of long-term exposure to hydrogen sulfide on human red blood cells.

BACKGROUND Hydrogen sulfide (H2S) exhibits both physiological and toxicological roles in the biological systems. Acute exposure to high levels of H2S is life threatening while long-term exposure to ambient levels of H2S elicits human health effects. OBJECTIVE To study the harmful effects of long-term exposure to low levels of H2S on human blood cells. METHODS 110 adult workers from Iran who...
