“…Amino‐acid‐based ILs demonstrate high EC 50 values to Scenedesmus quadricauda green algae and V. fischeri through suitable selection of cations and anionic amino acids, and some of the synthesized compounds are classifiable as nontoxic to both species. Among the selected amino acids, prolinate is the most toxic, whereas alaninate is the least toxic for S. quadricauda . Mandelate‐derived ILs demonstrate lower toxicity to C. vulgaris and P. subcapitata with EC 50 values 10 3 to 10 7 higher than those of the respective traditional ILs …”

This Review aims to integrate the most recent and pertinent data available on the (bio)degradability and toxicity of ionic liquids for global and critical analysis and on the conscious use of these compounds on a large scale thereafter. The integrated data will enable focus on the recognition of toxicophores and on the way the community has been dealing with them, with the aim to obtain greener and safer ionic liquids. Also, an update of the most recent biotic and abiotic methods developed to overcome some of these challenging issues will be presented. The review structure aims to present a potential sequence of events that can occur upon discharging ionic liquids into the environment and the potential long-term consequences.

“…Interestingly, the claim has yet to be experimentally proven. In our recent work [37], the variation of the toxicity of 1-(2hydroxylethyl)-3-methylimidazolium, [C 2 OHmim] by pairing it with four different types of amino acid anions namely glycinate, alaninate, serinate and prolinate was studied towards the V. fischeri. The reported EC 50 for the amino acid-based ILs was found to be greater than 5000 mg L -1 , which highlighted their non-toxic behaviour.…”

Ionic liquids (ILs) have gained significant attention within the academic and industrial circle owing to their attractive and unique characters. However, the usual green image of the ionic liquids mainly associated with their low vapour pressure has become increasingly doubtful. Several recent studies have highlighted the underestimated ILs toxicity which has not been adequately addressed. Therefore, improving the understanding of the ionic liquids toxicity towards aquatic organisms will undoubtedly lead to formulation of right solutions to address the toxicity problem hence contributing towards the development of green and sustainable ILs-based technology. The chapter provides a collective review of studies conducted on the effect of ILs structure on toxicity, specifically focussing on the various types of cations and anions, and the length of the alkyl chain attached. Based on the qualitative outcome from the review, a discussion on the development of statistical modelling on the impact of ILs structural features towards the overall toxicity is presented. The application of quantitative structure activity relationship (QSAR) for developing the predictive model for toxicity is highlighted.

“…Although these compounds have long been thought of as "green solvents" [9], there is an urgent necessity to explore and identify their effect on living beings in order to avoid negative consequences after unintentional exposure [10]. Research papers dealing with the environmental impact of ILs have become more numerous recently, although our understanding of the biodegradability and toxicity for ecosystems of most ILs is still limited [11][12][13][14][15][16][17][18][19]. Nowadays, the environmental legislation of the EU is mainly focused on the safety of chemicals, an objective that clearly requires ecotoxicological and biodegradation data [20].…”

This research compares the environmental properties (bacterial toxicity and biodegradability) of 12 ionic liquids-ILs-(7 phosphonium, 2 imidazolium and 3 ammonium cation-based ones), potentially applicable as lubricant additive, with two types of the traditional lubricant additive ZDDP. Aquatic toxicity was determined by means of Vibrio fischeri and Escherichia coli bacteria, while biodegradability was evaluated through biological oxygen demand (BOD 5) and chemical oxygen demand (COD) measurements. Regarding toxicity results, [P 4442 ][DEP] was the least toxic IL (acute 3 according to GHS) for both bacteria, whereas ZDDP fell into the acute 1 category (very toxic). All samples tested turned out to be poorly biodegradable, showing BOD 5 /COD values below 0.1. Two ILs showed better combined tribological and environmental properties than ZDDP.
