Abstract

Abstract:

Objective: It is of great significance to reveal the characteristics of non-methane hydrocarbons (NMHCs) emitted from the combustion of different tree species in order to calculate the total emissions of NMHCs in the process of different types of forest fires and to evaluate the impact on the atmospheric environment and human health. Method: The branch, leaves and bark of the typical tree species of Larix gmelinii, Pinus sylvestris var. mongolica, Quercus mongolica, Betula platyphylla and Populus davidiana in the Daxing'anling Mountains were used as objects. A biomass simulation combustion device was used to measure and analyze the emission factors and characteristics of NMHCs released by five tree species under different combustion conditions. The flue gas is collected by ASP-DC-1.2 electric sampler. NMHCs was determined by Entech 7100 preconcentration system and Agilent 7890A/5975 chromatography-mass spectrometry (GC-MS). The standard gas was a mixture of 57 kinds of non-methanes from Spectra Gases Inc., USA. Result: 1) A total of 48 NMHCs were detected, of which 19 were alkanes, 15 were alkenes, and 14 were aromatics. The 10 compounds with the largest emission factors accounted for 80.86% of the total NMHCs emission factors, among which i-Butane had the highest emission factor, accounting for more than 1/3 of the total NMHCs emission factor; 2) The emission factors (mg·kg^-1) of various compounds ranged from 359.88±101.43 alkanes of Pinus sylvestris var. mongolica to 756.54±205.47 alkanes of Quercus mongolica, and from 285.02±71.19 alkenes of Betula platyphylla to 358.72±92.60 alkenes of Larix gmelinii, and from 133.24±33.96 aromatics of Pinus sylvestris var. mongolica to 183.48±48.10 aromatics of Populus davidiana; 3) The average emission factor (mg·kg^-1) of NMHCs in the five tree species was 739.81±214.54 in the flaming state, and 1 284.91±405.72 in the smoldering state; 4) The average emission factors (mg·kg^-1) of leaves, branch and bark were 1 089.26±451.94, 918.44±237.80, and 1 029.39±413.84, respectively; 5)The emission factors (mg·kg^-1) of Quercus mongolica, Larix gmelinii, Populus davidiana, Betula platyphylla and Pinus sylvestris var. mongolica, and were 1 259.18±331.49, 1 111.56±248.53, 1 019.17±270.76, 889.05±235.58, 782.86±309.07, respectively; 6) The average ozone forming potential of the five tree species was 3.678 g·kg^-1. The ozone forming potential of alkanes, alkenes and aromatics accounted for 16%, 73% and 11% of the total, respectively. Conclusion: In the Daxing'anling Mountains, five typical arbor species emit three types of total non-methane hydrocarbons (alkanes, alkenes, and aromatics) when burning. Among them, i-Butane has the highest emission factor, and alkenes have the highest ozone forming potential. The total non-methane hydrocarbon release is related to combustion status. The overall combustion efficiency is low under smoldering condition, and the NMHCs emission factor is significantly higher than that of flaming combustion; There is no significant difference in carbon content among different biomass, so NMHCs emission factors do not show extremely significant differences. However, there are many influencing factors of NMHCs emission factors, leading to different average emission factors of non-methane total hydrocarbons by combustion in different tree species, the order is Quercus mongolica > Larix gmelinii > Populus davidiana > Betula platyphylla > Pinus sylvestris var. mongolica; the average emission factors of NMHCs in leaves and bark are slightly larger than those in branch.
