Effect study on three kind of polycyclic aromatic hydrocarbons on carotenoid content of three species in red tide microalgae 3种多环芳烃对3种赤潮微藻类胡萝卜素含量的影响研究
In this paper, photochemical degradation of polycyclic aromatic hydrocarbons ( PAHs ) from car exhaust under various conditions, including temperature, moisture content, light source, light intensity and exposure time, was investigated. 研究了不同条件(如温度、水蒸气含量、光源种类、光照强度和照射时间)下,汽车尾气中的多环芳烃(PAHs)的光化学降解。
The main components of the tar from sludge air gasification are composed of benzene and its compounds, polycyclic aromatic hydrocarbons, olefins and nitrogen-containing compounds, etc. Among the tar components, phenol and naphthalene are of the highest concentrations, about half of the total content. 污泥空气气化焦油主要成分包括苯及其化合物、多环芳烃、烯烃、含氮化合物等,其中苯酚和萘含量最高,大约共占总含量的一半。
