“As a result of the information published online about exceedances of the main air quality parameters registered by the alternative sensor networks, the permanent teams of the National Environmental Guard inside the Ilfov and Bucharest police stations monitored during the nights of 23 to 24 and 24 to 25 October, the areas where air quality sensors showed very large exceedances, Militari, Bragadiru, Rahova and Colentina. After verifications, the permanent team of the Ilfov County Police Station identified a possible source of contamination, a smelter that did not work during the control period, this being previously sanctioned by the representatives of GNM-CJ Ilfov. In this case, the preparation of a criminal file was also proposed “, according to a press release from the institution .
Police commissioners went to the Sinteşti-Ilfov area where there was not a very strong odor, but the source of the contamination could not be identified, the cited source adds.
“Subsequently, the GNM commissioners moved to the Sinteşti-Ilfov area, near Str. Zlătari, where a very strong odor was found. The exact source of contamination could not be identified during the inspection. According to information received from the official air monitoring stations, during the night of October 24/25 (approximately between 20-24) the concentrations of pollutants monitored within the RNMCA increased in almost all monitoring stations The value of PM 2.5 concentrations compared to PM 10 (approx. 80%) indicates the existence of combustion processes carried out at the beginning of the afternoon, the increase in concentrations being favored by the deficient dispersion of pollutants (almost total atmospheric calm established after 6:00 p.m.). Limit values were not exceeded, except for PM 10, where the mean daily concentration exceeded the limit values at stations B6 (60 micrograms / m3) and B1 (55 micrograms / m3). mos / m3). These values will later be validated by gravimetric measurements, by the reference method. The evolution of concentrations (PM10, PM 2.5 NO2, CO, benzene) and the meteorological indicators indicate possible causes of road traffic and residential heating with firewood in the peripheral areas of Bucharest ”, also transmit the representatives of the National Guard of the Environment in the press document.
The source also predicts that “although pollutant emissions were not significant, climatic factors influenced the dispersion of pollutants and caused these increases compared to the previous days.”
The permanent teams of the National Environmental Guard are ready to carry out the verifications Sunday night to see if the sensors will indicate new exceedances of the air quality parameters.
