ABSTRACT
  The ecotoxicological effects of 4-tert-octylphenol were observed on Harpacticoid copepoda Tigriopus japonicus s.l. gathered and cultured from tidal pool of Korean coast. There were no significant differences in survival rate (except 10 ㎍/ℓ; 70.00%) and sex ratio (except 30 ㎍/ℓ) on T. japonicus s.l. exposed to 4-lert-octylphenol. However, 4-rert-octylphenol induced developmental delay (copepodite emergence day and adult male mergence day) and retardation of first brooding day of adult female. Moreover the body size and biomass decreased at 4-tert-octylphenol exposure. As a result, detailed life-cycle research of T. japonicus s.l. may yield potential bioindicators for environmental monitoring and assessment.
Keywords: 4-tert-octylphenol; endocrine disrupter; copepod; Tigriopus japonicus s.l.; developmental delay
