Assessment of the road transport impact on green plants in the main streets of Birobidzhan

The authors present the results of green infrastructure vital status assessing under the road traffic impact in Birobidzhan. They calculated the index and total one-time emission of carbon monoxide from vehicles in different parts of the town. Most trees near the roads were found to be in impaired state (vital status index 0.50-0.70), especially the coniferous species. The more a distance from the town roads, the larger number of healthy trees was identified. The crossroads, located at the bypass roads with heavy trucks traffic, have the highest values of CO emissions (from 0.035 to 0.045 g/s). It was found a strong correlation between CO emissions and the vital status index of roadside green infrastructure, demonstrated by the r-Pearson correlation coefficients critical values (p=0.2319).
