Agricultural operations and processes generate copious quantities of particulate matter (PM) both directly and indirectly through emissions of PM precursor gases with dire consequences for human health, environment and climate. PM emissions from agricultural activities are projected to continually rise in the light of soaring food demand driven by a ballooning global population, and thus, plausible measures are needed to combat them. Recently, interest in using biochar to attenuate PM emissions of agricultural origin, especially the secondary PM precursors, has gained traction and this review study is purposed to examine the capacity of the technology to curb the agricultural-related PM emissions basing on observations made in the previously concluded studies. The study gives a brief overview of the effects of PM and delineates its weighty agricultural sources plus detailing whether and how the pyrolysis technology and biochar as its product can help to alleviate the emissions. Additional discussions address the looming dilemma of biochar applications becoming a PM emission problem and the techniques that should be applied to ensure its sustainable usage. It is overwhelmingly clear from the studies reviewed that pyrolysis and resultant biochar have an enormous potential to attenuate PM from agriculture if adequately utilised.

综述生物炭技术减少农业中颗粒物排放的潜力

农业运营和过程通过排放PM前体气体直接或间接产生大量的颗粒物(PM),对人类健康,环境和气候造成严重后果。鉴于全球人口激增推动的粮食需求激增,预计农业活动的PM排放量将持续增加,因此需要采取合理措施与之抗衡。最近,人们对利用生物炭来减少农业来源的PM排放物(特别是次生PM的前驱物)的兴趣日益增强,这项综述研究旨在根据在农业生产中观察到的技术,研究该技术遏制与农业相关的PM排放量的能力。先前完成的研究。该研究简要概述了PM的影响,并描述了其重要的农业来源,并详细说明了热解技术和生物炭作为其产品是否以及如何帮助减轻排放。额外的讨论解决了生物炭应用迫在眉睫的难题,成为PM排放问题以及应采用的技术,以确保其可持续利用。从所审查的研究中非常清楚地看到,如果充分利用热解和所产生的生物炭,具有巨大的潜力来减少农业中的PM。额外的讨论解决了生物炭应用迫在眉睫的难题,成为PM排放问题以及应采用的技术,以确保其可持续利用。从所审查的研究中非常清楚地看到,如果充分利用热解和所产生的生物炭,具有巨大的潜力来减少农业中的PM。额外的讨论解决了生物炭应用迫在眉睫的难题,成为PM排放问题以及应采用的技术,以确保其可持续利用。从所审查的研究中非常清楚地看到,如果充分利用热解和所产生的生物炭,具有巨大的潜力来减少农业中的PM。
