  • Abstract Polycyclic aromatic hydrocarbons (PAHs) are one of the persistent organic (POPs), which have the following characteristics: carcinogenic, bioaccumulation, biomagnification and long-distance shift with the atmosphere and biology. PAHs are mainly produced by the incomplete combustion of wood, coal and fossil fuels, influencing the land and marine ecosystems. Zooplankton are the primary consumer and play an important role in the marine food web. The observation of the PAHs accumulation in zooplankton provides us with more knowledge, which is essential information to further understand the spread of PAHs in the marine ecological environment. Zooplankton samples were collected at 16 stations in the Gaoping coastal waters from three Ocean Research III cruises: August, December 2014 and April 2015. Significant seasonal difference in zooplankton abundance was observed in the study, with the higher mean abundances in December (1246 ± 399 ind./m3) and April (1371 ± 521 ind./m3) than in August (463 ± 80 ind./m3). In general, copepods are the most dominant group (with a relative abundance >70%) at all sampling stations, except for April at station 1 (cladocera, 74%). The PAHs concentration of zooplankton ranged between 25 and 5440 ng / g dw. Higher PAHs concentrations were noted in Gaoping River estuary transect than in transects of Kaohsiung harbor and Fangshan. However, in terms of PAHs concentration of zooplankton biomass in seawater, PAHs concentration changed between 4 and 203 ng/m3, and the higher concentrations were found in Gaoping River estuary transect. Six PAHs, 1-Methylnaphthalene, 2-Methylnaphthalene, 2,6-Dimethylnaphthalene, Phenanthrene, Fluoranthene and Pyrene, produced by petroleum and petrochemical fuel, were the most abundant components in zooplankton in the study. They are common low rings PAHs in the marine environment. Among the above-mentioned components, the concentration of 2,6-Dimethylnaphthalene showed significant negative correlation with zooplankton abundance. The results demonstrated that the Gaoping coastal waters have been greatly influenced by petroleum pollutions produced from shipping and industrial activities.
