Source apportionment and fate simulation of polycyclic aromatic hydrocarbons (PAHs) in typical coastal port sediments: combining PMF-based and fugacity-based fate models
Longzhi Han
IntroductionCoastal ports are typical hotspots for polycyclic aromatic hydrocarbons (PAHs) accumulation. The complex pollution sources and constrained hydrodynamic conditions present significant challenges to the quantitative source tracing and fate simulation of PAHs.MethodsThis study used Qingdao Port (Jiaozhou Bay) as the research object, collecting 24 surface sediment samples. A positive matrix factorization (PMF) model was used to identify and quantify four main pollution sources. Using the
