摘要: Abstract Fifteen polycyclic aromatic hydrocarbons (PAHs) were detected in seawater and atmosphere of Bransfield Strait. The concentration ∑15[PAH] the ranged from 3.75 to 8.53 ng m−3, three-ring PAHs most abundant compounds. Dissolved 5.42 34.37 ng L−1, level was markedly different on each side strait. air–sea gas exchange process molecular diagnostic ratios calculated, results showed that environmental behavior net deposition along this cruise. Given changes global transport routes pollutants under warming, role long-range (LRT) may be enhanced. Taking Antarctic as a sink due LRT deposition, will continue load into area via atmospheric which contributes improving our understanding PAHs.
