In particular, it is reported that at night the concentration of hydrogen sulfide in the street Guryanova area Printmakers exceed the legislatively approved sanitary standard 1.3 — 4 times. Another street on which the excess weight was particularly significant was the street and Marshal Poluboyarov in the Vykhino-Zhulebino — here she was above maximum allowable indicators in 1,3-2 times. It is also reported that in Lublin, the concentration of hydrogen sulphide amounted to 1.37 and 1.7 MPC, in Maryino – 1.36 MPC

The high content of hydrogen sulfide, according to experts, can be explained by the fact that in Moscow a few weeks kept hot, Sunny and generally calm weather, and this leads to the fact that pollutants are dispersed inefficiently. However, the specialists of “Mosekomonitoring” note that at 9 a.m. on the territory of Moscow content in the atmosphere controlled substances does not exceed the standards established for the maximum single concentrations. It is also reported that expected during the day, intermittent rain and winds of 5-10 meters per second will contribute to the further improvement of the ecological situation in the capital. At the same time, experts urge to avoid a long stay, walks in territories where level of pollution of atmosphere exceeds 80 percent of the MCL. It is reported that in the first place, this recommendation applies to children, the elderly, people with diseases of the respiratory and cardiovascular systems, as well as pregnant women

Maximum permissible concentration — approved by law hygienic standard, indicating how the content in the atmosphere or other contaminant, according to available scientific data in the long term does not pose a threat to human health. It is noted that in some cases plants and animals can be harmful, and concentrations of some substances not exceeding MPC.
