COMPARISON OF ACUTE TOXICITY OF SIX DIFFERENT CHEMICALS WITH EISENIA FETIDA BIOASSAY

摘要

One of the most important targets of green chemistry is the use of renewable raw materials, that is, the production of chemicals from biomass rather than fossil resources, such as oil, natural gas, or coal. The main problems of using fossil resources are that they are not renewable and their availability is diminishing rapidly. Chemicals from sustainable sources, including those from biomass, which are usually obtained by fermentation, enzymatic, or esterification processes, can be used for a number of industrial processes. This is the case of the chemicals studied in this work: levulinic acid, ethyl levulinate, propyl levulinate and butyl levulinate.
