“…Several authors studied the acute toxic effects of these compounds on different aquatic organisms. [65][66][67] In general, SAILs showed moderate to high toxicity, depending on the model system used for toxicity evaluation. [68] It has been reported that the toxicity of ILs is much more affected by the structure of the cation than the anion, being the alkyl chain length considered as the main factor influencing its toxicity.…”

Twelve surface‐active ionic liquids (SAILs) and surface‐active derivatives, based on imidazolium, ammonium, and phosphonium cations and containing one, or more, long alkyl chains in the cation and/or the anion, were synthetized and characterized. The aggregation behavior of these SAILs in water, as well as their adsorption at solution/air interface, were studied by assessing surface tension and conductivity. The CMC values obtained (0.03–6.0 mM) show a high propensity of these compounds to self‐aggregate in aqueous media. Their thermal properties were also characterized, namely the melting point and decomposition temperature by using DSC and TGA, respectively. Furthermore, the toxicity of these SAILs was evaluated using the marine bacteria Aliivibrio fischeri (Gram‐negative). According to the EC50 values obtained (0.3–2.7 mg L−1), the surface‐active compounds tested should be considered “toxic” or “highly toxic”. Their ability to induce cell disruption of Escherichia coli cells (also Gram‐negative), releasing the intracellular green fluorescent protein (GFP) produced, was investigated. The results clearly evidence the capability of these SAILs to act as cell disruption agents.

“…The cause of this effect may be explained by the fact of the complex [anionic SAS (SAS-An) * cationic SAS (SAS-Ct)] formation. On the contrary, the toxicity of cationic surfactants amplifies with increasing water hardness (Lechuga et al 2016;Thomas et al 2009). The phenomenon of the nitrification braking in the presence of CaCO 3 is characteristic for the water in sections downstream of wastewater treatment plants (WWTP) of cities.…”

“…The presence of suspended solid particles and naturally occurring dissolved substances decreases the bioavailability of cationic surfactants but not that of anionic and nonionic ones (Lechuga et al 2016;Thomas et al 2009). In the presence of carbonate and silicate suspended particles, the SAS solutions manifest a specific behavior (Cui et al 2010;Cui et al 2012;Rosen and Kunjappu 2012;Spataru et al 2015).…”

“…Toxic surfactants from pesticides that have polluted natural sources of water have become a serious problem in recent decades (Lechuga et al 2016;Thomas et al 2009). It is known that the presence of surfactants in water can also lead to the solubilization of other oil-soluble pollutants such as DDT and trichlorobenzene (Scott and Jones 2000).The reported toxicities of surfactants vary widely over several orders of magnitude.…”

Influence of the interaction of calcium carbonate particles with surfactants on the degree of water pollution in small rivers

et al. 2017

Introduction: The influence of the interaction of calcium carbonate (CaCO 3 ) and surface-active substances (SAS; surfactants) with different chain lengths and cationic and anionic hydrophilic centers has been analyzed. Results: Laboratory simulations indicate reduced negative influences on cationic SAS nitrification/self-purification processes in the presence of anionic species. This suggests the role of complex ionic formation [anionic SAS * cationic SAS] as a cause of this effect. UV-Vis spectra of lauryl sulfate (LS) and of cetyltrimethylammonium (CTMA), as well as of their mixtures in ratios of 2:1 and 1:1, treated by fine particles of CaCO 3 , display decreased amounts of SAS in analyzed solutions and their presence on the surface of CaCO 3 nanoparticles. UV-Vis spectra reveal the decomposition of the complex [anionic SAS (SAS-An) * cationic SAS (SAS-Ct)] in solutions when CaCO 3 is added. CTMA can be bonded by LS through hydrophobic chains, on the surface of CaCO 3 particles. Therefore, CaCO 3 modifies the nature of LS and CTMA interactions. This leads to an increased degree of toxicity of cationic SAS in aquatic environment. The amounts of CTMA in aqueous solutions are diminished in the presence of ammonium ion NH 4 + (2 mg/L). In the presence of two orders higher concentration of ammonium ion, this effect strongly increases, making the association obvious. The structure of cationic SAS does not influence this effect. The obtained results have been confirmed both by timed natural aquatic sample analysis and laboratory simulations using water from Moldovan small rivers (Isnovat, Raut, and Bic). Conclusions: UV-Vis spectra and laboratory simulations demonstrate the change due to the addition of calcium carbonate. Simulations and laboratory tests of water samples from Isnovat, Bic, and Raut Rivers, establish the cationic SAS negative influence on treatment and self-purification processes.

“…Several eco-toxicity studies have also been carried out to understand the effect of surfactants on the ecosystem. Lechuga et al used four test organisms to assess the environmental risk of surfactants: a fresh water crustacean Daphnia magna, a bacterium Vibrio fischeri, a freshwater microalgae Selenastrum capricornutum and a seawater diatom Phaeodactylum tricornutum [14]. Their results indicated that the bacteria V. fischeri was the most sensitive organism while the freshwater alga S. capricornutum and D. magna were least sensitive to toxic effects of the surfactants.…”

Biolytic Effect of Rhamnolipid Biosurfactant and Dodecyl Sulfate Against Phagotrophic Alga Ochromonas danica

Surfactants can affect biological activities and pose serious threats to the aquatic ecosystem if discharged without proper treatment. Rhamnolipid is a biosurfactant with promising agricultural, industrial and biomedical applications. It is important to assess the risks posed by rhamnolipid before it is adopted for large scale use. In this study, toxicity of rhamnolipid was estimated with the effects of motility loss, membrane permeability, and cell lysis using a phagotrophic alga Ochromonas danica. O. danica is a sensitive algal species without a protective cell wall and it represents a group of phagotrophic flagellates ecologically important in the aquatic ecosystem. A common synthetic surfactant, sodium dodecyl sulfate (SDS), was used for comparison. Results suggested that rhamnolipid is significantly less biolytic than SDS and the effects required longer exposure. Lysis of O. danica cells by rhamnolipid was serious only at concentrations over its critical micelle concentration. Motility loss was, however, significantly more sensitive; about 75% loss after 20 min exposure to 50 mg/L rhamnolipid.
