对英国最丰富的树木、作物和植物物种的反应性非甲烷烃（NMHC）、异戊二烯和单萜烯的潜在排放进行了定性评估。大多数针叶树、一些落叶树和一些草本、草和作物物种排放一种或多种这些化合物。本文回顾了可能影响植被NMHC排放的因素，以及目前文献对英国NMHC排放率的估计。这些估计目前被认为非常不确定，但可能在50-100千万吨/年的范围内，单萜烯的排放量主要是异戊二烯的排放量。对不确定性的可能原因进行评估。
The potential emission of the reactive non-methane hydrocarbons (NMHC), isoprene and the monoterpenes, have been qualitatively assessed for the most abundant tree, crop and plant species in the U.K. Most coniferous trees, some deciduous trees, and a few herbaceous, grass and crop species emit one or more of these compounds. Factors likely to influence NMHC emissions from vegetation are reviewed as are current literature estimates of their emission rates for the U.K. These estimates are considered to be very uncertain at the present time, but may lie in the range 50-100 kt yr-1, with emissions of monoterpenes dominating those of isoprene. Assessment is made of the likely causes of uncertainty.
