1.Firstly, the biodegradation of biomarkers, such as pristane/phytane, hopanes, alkyl-PAHs have been studied by lab and field experiment.结果表明,在60天的降解时间内,三种原油BZ34-1、BXPT和SZ36-1中类异戊二烯类生物标志物姥鲛烷/植烷都发生了明显降解,降解率分别在15%~96%和20%~75%,姥鲛烷/植烷降解率随原油的密度增大而减小;而不同油品中姥鲛烷/植烷发生明显降解的阶段不同,对于轻质原油BZ34-1和BXPT,其姥鲛烷/植烷组分在实验初期(前20天)没有发生明显降解,实验中后期(20~60天)才开始被生物所利用;而对于重质原油SZ36-1,其姥鲛烷/植烷在生物降解初期就发生了显著降解。
