AB  - Estuaries are susceptible to both anthropogenic disturbances and global climate 
      changes. Impacts may be discriminated by pollution patterns of widely quantified 
      persistent organic pollutants (POPs), though data are scarce for extreme climate 
      events. This study quantified four groups of POPs, i.e., polycyclic aromatic 
      hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), 
      dichlorodiphenyltrichloroethanes (DDTs), and hexachlorocyclohexanes (HCHs), in 
      sediments from seven Chinese coastal estuaries across a gradient of socioeconomic 
      development in their watersheds with comparisons among the pre-typhoon, typhoon, 
      and post-typhoon periods during 2016-2019. The maximal average concentrations, up 
      to 1561 mug PAHs kg(-1), 235 mug DDTs kg(-1), and 38.9 mug HCHs kg(-1), were 
      quantified in the Jiulong River estuary and 7.61 mug PCBs kg(-1) in the Jiao River 
      estuary. Anthropogenic activities contributed to the distinctive spatial 
      distributions of four groups of POPs in estuaries with non-agricultural gross 
      domestic product (NAGDP) per capita significantly relating to sedimentary 
      concentrations of PAHs and PCBs and agricultural gross domestic product (AGDP) 
      per capita relating to DDTs and HCHs. Seasonality and typhoons led to less 
      temporal variations in sedimentary POPs concentrations, whose spatial 
      heterogeneity was remarkably reduced in the post-typhoon period rather than in 
      the pre-typhoon and typhoon periods. The results of this study suggested that 
      fingerprinting legacy POPs in spatial and temporal distributions contributed to 
      identifying the effects of anthropogenic disturbances and climate changes on 
      estuarine sediment quality.
