Review of higher plant toxicity and biodegradation of ionic liquid

As the green solvent, ionic liquids have certain toxicity, and it's incompleted degradation will cause huge damage to the environment. The study of ionic liquids toxicity to the higher plants focused on its impact on seed germination and seedling growth. The biodegradablity of imidazole and pyridine ionic liquids are not ideal; amino ionic liquids with biodegradability, low toxicity and high biocompatibility will become new research direction. Exploring the impact of ionic liquids on plant life cycle, designing readily biodegradable ionic liquids, screening dominant bacteria that have high degrading effect to ionic liquids through genetic engineering and building a comprehensive QSAR models of ionic liquid toxicity and biodegradability, will be the main studies in the future.
