楚科奇海陆架沉积物中几种低环的多环芳烃的垂直分布特征
THE VERTICAL PROFILE OF SEVERAL LOW-RING POLYCYCLIC AROMATIC HYDROCARBONS IN SEDIMENTS OF THE CHUKCHI SEA SHELF
摘要
Abstract
We collected 4 sediment cores in Chukchi Sea shelf during the 6th Chinese Arctic Expedition in 2014, and then surveyed overall level of several low ring PAHs in sediment cores. We discussed the vertical dis-tribution and historical sedimentation of the cores with the210Pb age dating. The results showed that the concentrations of several individual PAHs in Chukchi Sea shelf sediments varied from 50 to 1553 ng·g–1, those low ring PAHs in sediments are generally at a low level and it is not related to the grain size obviously. The sediment rate in Chukchi Sea shelf sediments varied from 0.05 to 0.19 cm·a–1. Concentrations of low ring PAHs varied slightly in sediment cores, human activities can hardly affect this area. Partial peaks in sediments may influenced by petroleum seep or diagenetic process.关键词
