High h2s levels
WebAt high concentrations H2S has a sweet odour but it may be undetectable by humans at those levels due to olfactory fatigue (may occur at approx. 100 µL/L with a 2 – 15 min exposure) or olfactory paralysis (approx. 150 µL/L). As H2S is slightly heavier than air (specific gravity of 1.189) it may accumulate in low-lying, unventilated areas. WebLaboratory results showed that, the hydrogen sulfide emission in digesters could be effectively and economically controlled by the addition of iron dosing. Slightly higher than …
