We conducted three experiments to estimate the toxicity of POPs (persistent organic pollutants) on two copepod species (Acartia erythraea and A. omorii) and Artemia sp.; (1) 48 h-LC$_{50}$ of A. omorii with the five PAHs [polycyelic aromatic hydrocarbons anthracene, benzo¡²a¡³pyrene, fluoranthene, phenanthrene, pyrene¡³ which were often detected in the Gwangyang Bay, (2) toxicity of benzo¡²a¡³pyrene and TBT on Artemia in different temperatures (1$0^{circ}C$, 15$^{circ}C$, 2$0^{circ}C$), (3) effects of benzo¡²a¡³pyrene and TBT on egg Production rate, hatching rate and fecal Pellet Production of two copepod species (A. erythraea and A. omorii) fed on Heterocapsa triquetra (dinoflagellate) exposed in benzo¡²a¡³pyrene. Toxic chemicals which were most effective to A. omorii were flueranthene (48 h-LC$_{50}$ 19.20 $mu extrm{g}$ L$^{-1}$ ) and benzo¡²a¡³pyrene (48 h-LC$_{50}$ 29.89 $mu extrm{g}$ L$^{-1}$ ). The toxi- city of chemicals to Artemia increased when temperature increased. The toxicity of TBT was about 100 times higher than that of benzo¡²a¡³pyrene at 15$^{circ}C$. Food materials (Heterocapsa triquetra) exposed in benzo¡²a¡³pyrene, affected negatively the rate of egg production, hatching rate and the fecal pellet production of the copepods at the high concentration. It is suggested that an increase in the concentration of benzo¡²a¡³pyrene might offset the production of copepods in marine ecosystems. This study suggests that copepods may be used as n indicator for early warning of the risk of POPs in marine ecosystems.
