Sensibity of two procedures to estimate the impact of the ionic liquid 1,3-Dimethylimidazolium Dimethyl Phosphate ([MMIM][DMP]) on soil microbial activity

| Sumario: | Ionic liquids are playing an increasingly relevant role in green chemistry due to one of their main important characteristic, their negligible vapour pressure, which means they are non-contaminant (o harmless) to the atmosphere. Nevertheless, they could be toxic for terrestrial ecosystems and therefore research to assess its toxicity to aquatic and terrestrial environments should be performed to assess whether they are as innocuous as sometimes assumed. The 1,3 dimethylimidazolium dimethylphospate, [C1C1Im][DMP], is an imidazolium ionic liquid with potential use in several industrial applications. Thus estimating the toxicity of this compound to these terrestrial ecosystems is of priority. In this study, we investigated the impact of different amounts of 1,3-dimethylimidazolium dime thyl phosphate ([C1C1Im][DMP]) on soil microbial activity by using two different methods: isothermal microcalorimetry and the classical method for meas uring basal soil respiration. The aims of the study were to estimate the toxicity of this compound to soil microorganisms, to assess whether both methods were equally sensitive to estimate the impact of this ionic liquid on soil microbial activity and to combine the information obtained by both methods to obtain a more insightful picture of the impact of this compound on soil microbial activity. |
