Hydrogen Sulfide Public Health Statement ATSDR
WebBasis for original (SCP) IDLH: The chosen IDLH is based on the statements by Patty [1963] that 170 to 300 ppm is the maximum concentration that can be endured for 1 hour without serious consequences; 400 to 700 ppm is dangerous after exposure of 0.5 to 1 hour [Henderson and Haggard 1943]. WebThe SPM detection limit is 1-90 ppb or 50-1500 ppb for the hydrogen sulfide calibration. H 2 S concentrations from the 1-90 ppb calibration are 15-min average readings that the instrument itself averages after sampling for an entire 15-min period. small ship greek islands cruise
