Air quality dynamics

Since data from the automatic monitoring stations is received in real time (without prior examination), cases of incorrect data representation or temporary absence of data are possible due to absence of connection or malfunction of the equipment

Hydrogen sulfide (H2S) concentrations are compared with the level, recommended by the World Health Organization (WHO) in Air Quality Guidelines for Europe as a level at which first effects on health can be observed (eye irritation).
Hydrogen sulfide (H2S) is a gaseous chemical compound with specific odor.
0,007 mg/m3 Odor threshold

Odor threshold for hydrogen sulfide (concentration, at which an odor can be smelled) according to the World Health Organization (Air Quality Guidelines for Europe) is 0.007 mg/m3. In the Russian Federation maximum allowable short-time concentration in ambient air (MACst) is set at an odor threshold level (0.008 mg/m3).

However, concentrations of hydrogen sulfide, which can cause reversible effects on health of the sensitive groups of population, are much higher than the odor threshold.

0,15 mg/m3 Health impact threshold

In the World Health Organization guidelines on air quality for Europe a recommended concentration which can cause first reversible effects on health (eye irritation) is 0.15 mg/m3 which is 18.75 times higher than the odor threshold. According to the special WHO report on effects of hydrogen sulfide on health, reversible effects on health of the sensitive groups of population (people with asthma and allergies) are observed at 2.8 mg/m3, which is 350 times higher than the odor threshold.

In order to provide objective assessment of the impact of the observed hydrogen sulfide concentrations on public health, here we represent these concentrations as parts of the WHO recommended limit level (0.15 mg/m3)
