Abstract


Black carbon absorbs solar radiation. Its sedimentation period is relatively short. The main sources of airborne black carbon in Central Yakutia is forest fires. The objective of the present study is to assess the effects of different back carbon levels in the air on photosynthesis in the leaves of the birch tree Betula platyphylla Sukacz. Airborne black carbon monitoring was carried out at the forest research station Spasskaya Pad’ located 30 km to the north from Yakutsk. It was found that elevated black carbon levels in the air significantly compromise photosynthetic process in birch leaves.

Keywords
