Isoprene emission from the forest of Haryana state.

Tropical and sub tropical regions are regarded as dominant source of biogenic volatile organic compounds emission (BVOC). However, measurement studies from these regions are limited and largely confined to South Africa and Amazonia. Consequently, global BVOC estimates are mainly based on modeling studies. Moreover, BVOC emission estimate is altogether lacking for any region of the Indian sub continent. This study attempts to estimate isoprene emission capacity of forest of Haryana state. Individual plant species isoprene emission capacity is found to vary from below detection limit (BDL) to 12.01 mg Cm(-2) h(-1). Maximum emission capacity (12.01 mg Cm(-2) h(-1)) is noticed in case of Dalbergia sissoo. The area average isoprene emission capacity for the Haryana forest is found to be 19.98 mg Cm(-2) h(-1), which is significantly (2.4 times) higher than the reported isoprene emission value of 8.2 mg Cm(-2) h(-1) for the Kalahari woodland of Africa.
