Polycyclic Aromatic Hydrocarbons Processing by a Fog Cloud - Field and Laboratory Studies

这个项目解决了关于多核芳烃（PAHs）雾中的化学处理的问题，其中一些已知是有毒的。具体来说：多环芳烃的雾处理是否有可能将它们转化为氧化化合物（含氧多环芳烃）或颗粒？一些含氧多环芳烃可能有毒吗？如果是这样，这些化合物如果在雾蒙蒙的环境中被吸入，也可能对健康构成潜在威胁。该方法包括在加利福尼亚州弗雷斯诺附近和/或路易斯安那州立大学的烟雾-雾-烟雾（SFS）循环中对多环芳烃和氧-多环芳烃的相位分布进行现场测定。更广泛的影响包括对大气水体中多环芳烃循环的新观点，这是广大科学家感兴趣的。来自代表性不足群体的研究生正在通过参与该项目接受培训。参加活动的还有一名来自Prairie View A&amp；M大学的教员，这是一所历史悠久的黑人大学。研究成果将被纳入首席研究员教授的本科课程。

This project addresses questions regarding the chemical processing in fog of polynuclear aromatic hydrocarbons (PAHs), some of which are known to be toxic. Specifically: Is there a possibility that fog processing of PAHs could transform them to oxidized compounds (oxy-PAHs) or particles? Might some of the oxy-PAHs be toxic? If so, these compounds might also represent a potential health threat if they are inhaled in a foggy environment. The approach consists of field determination of phase distributions of PAHs and oxy-PAHs throughout smog-fog-smog (SFS) cycles near Fresno, CA and/or at Louisiana State University. Broader impacts include new perspectives on the cycling of PAHs in atmospheric waters, which are of interest to a broad range of scientists. Graduate students from underrepresented groups are being trained through their participation in the project. Also participating is a faculty member from Prairie View A&M University, a Historically Black College-University institution. Research results are being incorporated into undergraduate courses taught by the principal investigator.
