摘要

本研究的目的是根据《日本化学物质管制法》,建议使用OxiTop®测量生化需氧量(BOD),以正确评估真实环境中的化学命运。在我们之前的研究中,通过用氯仿将化学物质吸附到硅胶上和将介质体积从300增加到3900,加速了测试化学物质的生物降解 mL。然而,由于硅胶中的三氯甲烷残留物,无法根据BOD评估这些化学品的生物降解性,或者由于库仑计的烘箱尺寸,无法进一步增加介质体积。在这项研究中,我们使用OxiTop®建立了一个基于BOD的评估系统,将培养基体积增加到9000 mL。基于一式三份的测试,增加培养基体积加速了生物降解并减少了BOD的变化。

Establishing a ready biodegradability test system using OxiTop® to evaluate chemical fate in a realistic environment
The purpose of this study is to propose the use of OxiTop® for measuring biochemical oxygen demand (BOD) under the Japanese Chemical Substances Control Law in order to properly evaluate chemical fate in a real environment. In our previous study, the biodegradation of test chemicals was accelerated by both adsorbing the chemical to silica gel with chloroform and increasing the medium volume from 300 to 3900 mL in the OECD 301F test using a coulometer. However, the biodegradability of these chemicals could not be evaluated based on BOD due to chloroform residue in the silica gel, or the medium volume could not be increased further due to the oven size of the coulometer. In this study, we established an evaluation system using OxiTop® based on BOD by increasing the medium volume to 9000 mL. Based on triplicate testing, increasing the medium volume accelerated biodegradation and decreased variation in BOD.
