气尘埃，但它的主要成分是丙烷等碳氢化合物，使用不当会发生中毒事故。这些燃料燃烧时都需要消耗室内氧气而排出一氧化碳、二氧化碳、二氧化硫、氮氧化会物、醛类、苯并芘以及烟灰微细尘粒等有毒气体和颗粒，这对神经系统、眼结膜和呼吸道粘膜有刺激性，并且具有潜在的致癌性。

These fuels need to consume indoor oxygen to discharge toxic gases and particles such as carbon monoxide, carbon dioxide, sulphur dioxide, nitrogen oxides, aldehydes, benzopyrene and fine dust particles, which are irritating to the nervous system, eye conjunctiva and respiratory mucosa, and have potential carcinogenicity
