Growth inhibition test using <i>Chlamydomonas reinhardtii</i> were performed to estimate a toxicity to alkylphenols under short-term cultural length. C1-10-Alkylphenols, 4-Butoxyphenol(ButoP), Bis-phenol-A(BPA), Di-2-ethylhexyl phthalate (DEHP) and 17β-Estradiol as a chemical substances were added and tested to determine ErC<sub>50</sub> for growth inhibition of <i>Chlamydomonas reinhardtii</i> in this study.<br>Through the result of growth inhibition test of <i>Chlamydomonas reinhardtii</i>, the difference between 0-24h ErC<sub>50</sub> and 0-72h ErC<sub>50</sub> were found in dose of 4-t-Octylphenol and 4-Nonylphenol, and sensitivity of short term test for 24 hours was rather higher than that of conventional 0-72h algal inhibition test. In addition, high negative correlationship between log 24h-ErC<sub>50</sub> of alkylphenols BPA to <i>Chlamydomonas reinhardtii</i> and their log Pow was recognized in short-term growth inhibition test under the various combination of eleven alkylphenols except for ButoP and DEHP.<br>It is indicated that toxicity of alkylphenols to growth of <i>Chlamydomonas reinhardtii</i> is sensitively estimated in short-term test within 24 hours.
