Vinyl samples were burned in a controlled environment to determine the characteristics of particulate matter (PM) and volatile organic compound (VOC) emissions during the combustion process. Open burning of plastic or vinyl products poses several environmental and health risks in developed and developing countries, due to the release of high concentrations of harmful pollutants. The production of fine and ultrafine particles was significant. At a heat flux of 25 kW/m², the production of PM of 0.35 μm in size was highest at 63.0 μg/m³. In comparison, at fluxes of 35 and 50 kW/m², the production of PM of 0.45 μm in size was highest with values of 67.8 and 87.7 μg/m³, respectively. Benzene, acetone, and other toxic compounds were also identified in the analyses.
将乙烯基样品在受控环境中燃烧,以确定燃烧过程中颗粒物 (PM) 和挥发性有机化合物 (VOC) 排放的特性。在发达国家和发展中国家,由于释放出高浓度的有害污染物,塑料或乙烯基产品的露天燃烧会带来一些环境和健康风险。细颗粒和超细颗粒的产生量很大。在热通量为 25kW/m²时,粒径为 0.35μm 的 PM 产量最高,为 63.0μg/m³。相比之下,在通量为 35kW/m²和 50kW/m²时,粒径为 0.45μm 的 PM 产量最高,分别为 67.8μg/m³和 87.7μg/m³。分析中还鉴定出了苯、丙酮和其他有毒化合物。
