Abstract

The ecotoxicological effects of 4-tert-octylphenol were observed on non-biting midge, Chironomus plumosus collected from Anyang stream in Seoul. The survival rate and adult emergence rate on C. plumosus exposed to octylphenol were not significantly affected. However, 4-tert-octylphenol induced developmental delay and disrupted sex ratio in high concentration of octylphenol. The mouth deformity such as tooth deletion or fusion in mentum, and tooth deletion in mandible were observed exposure to 4-tert-octylphenol. The deformity type of the mentum showed deletion (LT, 6.7%), and fusion (LT, 6.3%). Moreover, tooth deletion of mandible was observed in 4-tert-octylphenol treated groups (6.7%, 3 ppm).
