Abstract

Dichloromethane (DCM) is a toxic pollutant showing prolonged persistence in water. DCM biodegradation is usually determined from increases in Cl ions, gas chromatography, or by using radioisotopes. Herein, we present an original and easy spectrophotometric method to estimate DCM concentrations in cultures and environmental samples during DCM biodegradation experiments.

摘要

二氯甲烷（DCM）是一种有毒污染物，在水中具有较长的持久性。DCM的生物降解通常通过Cl离子的增加、气相色谱法或使用放射性同位素来测定。在此，我们提出一种新颖且简便的分光光度法，用于在DCM生物降解实验期间估算培养物和环境样品中的DCM浓度。
