Infrared observations indicate that this nebula may contain complex carbon molecules known as PAHs.
红外观测器还发现这个星云可能含有叫作多环芳烃的复杂碳分子。Chlorinated aromatic hydrocarbons and their derivatives are the persistent organic compounds, which are toxic or not easy to degrade.
氯代芳烃及其衍生物是一类毒性强、难降解的持久性有机化合物。The oil-extended rubber obtained from rubber aromatic oil is of good processibility with satisfactory mechanical properties.
橡胶芳烃油生产的充油橡胶具有良好的工艺性能和机械性能。Polycyclic aromatic hydrocarbons (PAHs) are known as toxic, mutagenic, carcinogenic and persistence organic contaminants in the environment.
多环芳烃是一类普遍存在于环境中的难降解的危险性“三致”有机污染物。This arc is made up primarily of organic compounds called polycyclic aromatic hydrocarbons, which glow on the surface of the cloud.
这个弧形主要由稠环芳烃构成，这些有机化合物在云雾区域的表面发光。PAHs are a group of chemicals that are formed the incomplete burning of coal, oil and gas, garbage, or other organic substances .
多环芳烃是一组化学物质，他们是由未经完全燃烧的煤。油和气。垃圾。或是其他有机物质形成的。Therefore, PAHs ubiquitously and widely distribute in the environment, so people could intake PAHs through the atmosphere, water and food.
因此多环芳烃在环境中无所不在，分布十分广泛，人体可能通过大气、水、食品等途径摄入多环芳烃。The invention discloses halomonas capable of degrading polyaromatic hydrocarbon and application thereof.
本发明公开了一株可降解多环芳烃的盐单胞菌及其应用。A large number of potential carcinogens can be released in incense smoke, including polyaromatic hydrocarbons, carbonyls, and benzene.
大量的潜在的致癌物随熏香的烟雾散发，包括多环芳烃，碳氢化合物，羰基和苯。
