南极菲尔德斯半岛多环境介质中多环芳烃分布特征及环境行为研究
DISTRIBUTION AND ENVIRONMENTAL BEHAVIOR OF PAHs IN DIFFERENT MATRIXES ON THE FILDES PENINSULA, ANTARCTICA
摘要
Abstract
Water, sediment, moss, penguin-droppings, and organism samples were collected from the Fildes Peninsula to investigate the distribution and environmental behavior of sixteen polycyclic aromatic hydrocarbons (PAHs).The results showed that the total PAH concentrations in water , sediment, moss, penguin-droppings, and organisms were 34.9-346 ng· g-1(mean=184 ng· L-1), 68.9-374 ng· g-1(mean =188 ng· L-1), 122-894 ng· g-1 (mean=251 ng· L-1), 197-293 ng· g-1(mean=245 ng· L-1), and 137-443 ng· g-1(mean=265 ng· L-1 ) , respectively .Compared with other regions , the proportions of 2-3 ring PAHs to total PAHs were higher than 0.5, whereas the proportions of 5-6 ring PAHs were less than 0.2 in all environmental compartments , indi-cating that atmospheric transfer was the main source of PAHs .Significant log/log-linear relationships between the soil/moss quotient (QSM) and the sub-cooled liquid vapor pressure (poL) and octanol-air partition coefficient (KOA) were observed .Furthermore , similar significant log/log-linear relationships between the octanol-water partition coef-ficient ( KOW ), the biota/water quotient ( QOW ), and the penguin-organism/penguin-droppings quotient ( QPD ) were also observed .The results indicated that the concentration ratios between different media could be veiwed as a mirror image of the distribution behavior of PAHs in the remote polar regions .关键词
