Emissions of monoterpene from tropical Indian plant species and assessment of VOC emission from the forest of Haryana state

Abstract

Monoterpene emission samples of 50 Indian plant species were collected using a dynamic flow–through enclosure chamber technique and concentrations were determined with the help of GC–FID/MS. Monoterpene emission rates of different plant species ranged from negligible to 16.9 µg g–1 h–1. Thirty four of the screened fifty plant species, were found to be monoterpene emitters. Volatile organic compound (VOC) emission capacity of predominantly plantation forest of Haryana was also estimated, which was found to be 20.9mg C m–2 h–1. Individual plant species area averaged VOC emission capacity ranged from negligible to 12.0mg C m–2 h–1. Dalbergia sisoo and Eucalyptus globulus, were found to contribute approximately 82% of the total VOC emission capacity.
