Sensors will be installed to monitor air pollution at 22 locations in Sofia. They will be part of the municipal network and are expected to start operating by the end of the year, reports Mediapool.
Sensor information will be available in real time on the Internet. Other sources of information on the state of the air, such as the stations of the Executive Environment Agency or the civil sensors data from the airsofia.info platform, may be added to the platform on which it will be uploaded. "The goal is to use information for decision-making," explained Deputy Mayor of Ecology in Sofia Municipality, Yoanna Hristova.
Currently there is a selection of contractor for delivery and mounting of the sensors. Two companies are participating in the tender - Telelink Business Services and A1 Bulgaria. The estimated value of the order is over BGN 560 000 excluding VAT.
Sensors should measure the concentration of the most popular pollutants - fine particulates, carbon dioxide, nitrogen dioxide and sulfur dioxide, as well as temperature, humidity and pressure.
The facilities will be placed near Lyulin and James Baucher metro stations, to the tram number 10 at West Park, President Lincoln Boulevard, Iskra Chitalishte in Orlandovtsi, Central Bus Station, Vrazhdebna Polyclinic, to the Center for Infectious Diseases, Military Medical Academy, Mimi Balkanska Street, to NIMH on Tsarigradsko shosse Blvd., to the Winter Palace, to Rakovski Stadium, to the 29th DCC in Sofia. "Borovo", to the Hipodruma automatic station and to St. Cyril and Methodius Chitalishte in "Dragalevtsi" district, as well as to the adjacent administrative districts instances of Nadezhda, Krasna Polyana, Poduyane, Ovcha Kupel, Iskar and Studentski.
The sites are selected on the basis of a survey on the climatic and geographic features of Sofia, according to data on traffic, population distribution, building and use of the capital's territory. The idea is to be located evenly in neighborhoods and districts, in places where more people live and where there are municipal buildings or properties to which they can be installed. After selecting a contractor, there may be a change of locations because the company needs to check if it is practically possible to place the appliances on the specified locations.
Separately, local authorities are also planning to buy a mobile station to measure air pollution to be used in cases of local pollution.
