As a group of derivatized PAHs,hydroxyl polycyclic aromatic hydrocarbons(OH-PAHs) are known as newly recognized pollutants even with higher toxicities than their parent PAHs.The OH-PAHs are potentially ubiquitous in the polar snow and ice due to the feasible transformation of local existing PAHs into OH-PAHs.Therefore,it is of great significance to investigate their transformation to assess the persistence and fate in the Arctic/Antarctic environment.The present study selectes four OH-PAHs [9-Hydroxyfluorene(9-OHFl),2-Hydroxy-fluorene(2-OHFl),9-Hydroxyphenanthrene(9-OHPhe),and 1-Hydroxypyrene(1-OHPyr)],and investigates their photodegradation kinetics and intermediates in ice to elucidate the photochemical fate in Arctic and Antarctic ice/snow environment.
