通过莱茵衣藻的生长抑制试验来评估短期培养长度下对烷基酚类物质的毒性。以氯代-10-烷基酚、4-丁氧基苯酚、双酚A、邻苯二甲酸二乙基己酯和17-β-雌二醇为化学物质，测定其对莱茵衣藻生长抑制的ErC50。通过对莱茵衣藻的生长抑制试验，发现4-辛基酚和4-壬基酚对莱茵衣藻的生长抑制作用在0-24小时和0-72小时的ERC50之间存在差异，24小时短期抑制试验的敏感性高于常规的0-72小时抑制试验。此外，在除ButoP和DEHP外的11种烷基酚的短期生长抑制试验中，烷基酚BPA对莱茵衣藻的对数24小时-ErC50与它们的对数POW呈高度负相关。说明在24小时内的短期试验中，烷基酚对莱茵衣藻的毒性是敏感的。
Growth inhibition test using Chlamydomonas reinhardtii 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 ErC50 for growth inhibition of Chlamydomonas reinhardtii in this study.Through the result of growth inhibition test of Chlamydomonas reinhardtii, the difference between 0-24h ErC50 and 0-72h ErC50 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-ErC50 of alkylphenols BPA to Chlamydomonas reinhardtii and their log Pow was recognized in short-term growth inhibition test under the various combination of eleven alkylphenols except for ButoP and DEHP.It is indicated that toxicity of alkylphenols to growth of Chlamydomonas reinhardtii is sensitively estimated in short-term test within 24 hours.
