Tóm tắt

 Marine sediments are an important sink for global polycyclic aromatic hydrocarbons (PAHs)
  however, the influence of seasonal hydrodynamic conditions on sedimentary PAHs along the continuum of large river-estuary-shelf systems remains unclear. Surface sediment samples collected from the Yangtze River Estuary (YRE) in winter (March 2015) and summer (July 2019) were analyzed for the sixteen USEPA priority PAHs (16 PAHs). The total concentration of 16 PAHs was substantially lower in winter (13.3-318.9 ng g
