Norq Marash – One of Clean Administrative Areas in Yerevan
Norq Marash is one of relatively clean administrative areas in Yerevan, as EcoLur’s Ecological Risk Assessment Model shows. The total amount of emitted harmful substances for 2012 made up 29.11 tons: dust - 6.73 tons, carbon monoxide (CO) - 7.91 tons, nitric oxide (NO) - 2.53 tons.
The model has assessed the situation with emissions in different administrative areas of Yerevan due to the data provided by various enterprises to the State Environmental Inspection of Nature Protection Ministry in 2012. As a standard, the model considers the emission of the least polluted area in Yerevan, which, in our case, is Nubarashen area with its total amount of emissions of 3.37 tons, dust – 1.6 tons, nitric oxide – 0.28 tons, carbon monoxide - 1.49 tons and nitrogen dioxide – 0 ton.
The model assesses pollution in line with the following principle - if the emissions exceed the standards by 10 times, the situation is assessed as poor, if by over 20 times, which lasts for two days, the situation is assessed as critical, if by 30-50 times and lasts for over 8 hours, the situation is assessed as disastrous.
