摘要

泥炭地火灾向空气中释放的多卤芳烃对环境健康造成重大危害。马来西亚泥炭地火灾对环境污染的贡献不断增加。此类火灾产生的烟雾成分在阐明健康风险方面起着关键作用。因此,必须对烟气中的多卤芳烃同系物进行评价。本研究的重点是马来西亚半岛的两个泥炭地森林,包括活跃的燃烧地点:雪兰莪的瓜兰加和彭亨的贝干。对燃烧点和抑制点的烟雾样本进行了多氯二苯并对二恶英和呋喃(PCDD/Fs)和二恶英样多氯联苯(dl-PCBs)粒子数浓度(PNC)和颗粒质量(PM)浓度分析。在目前的研究中,我们发现燃烧过程中PCDD/Fs/dl-PCBs TEQ的危险水平高达80.74 fg/m3,而烟雾中的主要同系物分别是1,2,3,4,6,7,8- hpcdf(高达23.38 pg)和PCB-126(高达34.41 pg)。泥炭地火灾的烟雾分析显示,与非火灾日相比,PNC和PM质量浓度显著升高。每小时PM比分析显示,在泥炭地火灾和非火灾日,细颗粒物是环境空气中的主要成分,表明PM质量与PNC之间存在很强的关联。因此,本研究确定泥炭地火灾构成重大的健康危害,强调需要对特定地点的烟雾成分进行分析,以有效管理健康危害。

Peatland fires in Peninsular Malaysia act as primary source of dioxins, dioxin-like polychlorinated biphenyl, and particulate matter

The emissions of polyhalogenated aromatic hydrocarbons released in the air from peatland fires pose significant environmental health hazards. The contribution of peatland fires to environmental pollution is increasing continually in Malaysia. The composition of the smoke emerging from such fires plays a pivotal role in elucidating health risks. Therefore, the polyhalogenated aromatic hydrocarbon congeners must be assessed in the released smoke. The present study focused on two peatland forests in Peninsular Malaysia, comprising the active burning sites: Kuala Langat in Selangor and Pekan in Pahang. The smoke samples from the burning and burning-suppressed sites were analyzed for polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs) and dioxin-like polychlorinated biphenyls (dl-PCBs) particle number concentration (PNC) and particulate mass (PM) concentration. In the current study, we found hazardous levels of PCDD/Fs/dl-PCBs TEQ as high as 80.74 fg/m3 during the burning and 1,2,3,4,6,7,8-HpCDF (as high as 23.38 pg) and PCB-126 (as high as 34.41 pg) as the predominant congeners in the smoke, respectively. The smoke analysis of peatland fires revealed a significantly higher concentration of PNC and PM mass compared to a non-fire day. The analysis of the hourly PM ratios revealed fine particles as the dominant component in the ambient air during the peatland fires and non-fire days, indicating a strong association between PM mass and PNC. Thus, the present study establishes that peatland fires pose a significant health hazard, emphasizing the need for site-specific profiling of smoke constituents for effective management of health hazards.
