OECD validation study to assess intra- and inter-laboratory reproducibility of the zebrafish embryo toxicity test for acute aquatic toxicity testing.
Synthesis, toxicity, biodegradability and physicochemical properties of 4-benzyl-4-methylmorpholinium-based ionic liquids
It was found that new 4-benzyl-4-methylmorpholinium-based ionic liquids with anions commonly used for dissolving cellulose, such as formate or acetate, can also be used as new biomass solvents.

Investigation of the effect of low concentration of two widely used pyrethroids--cypermethrin and deltamethrin on phyto- and zooplankton found 13% growth inhibition of Chlorella vulgaris (statistically insignificant) after 14 days of exposure to deltAMethrin as well as cypermethin was observed.
Acute toxicity of nine pesticides as determined with conventional assays and alternative microbiotests
- P. Fochtman
Toxkit microbiotests seem to be a tempting alternative to conventional bioassays in aquatic toxicology because they are time and space consuming and depend on the continuous culture and maintenance of the test species.
CON4EI: Slug Mucosal Irritation (SMI) test method for hazard identification and labelling of serious eye damaging and eye irritating chemicals.
Betaine and Carnitine Derivatives as Herbicidal Ionic Liquids.
The obtained results suggest that the synthesized herbicidal ionic liquids displayed low toxicity and showed similar or improved efficacy against weed compared to reference herbicides.
Herbicidal ionic liquids based on esterquats
Novel herbicidal ionic liquids (HILs) containing different anions and cations derived from ammonium esterquats were prepared by employing a simple, inexpensive pathway. The basic physicochemical…
The use of conventional bioassays, microbiotests, and some “rapid” methods in the selection of an optimal test battery for the assessment of pesticides toxicity
Principal component analysis (PCA) separated unicellular and multicellular organisms in regard to their sensitivity to pesticides and provided more detailed insight into the “connections” within the separated group of biotests.
CON4EI: Short Time Exposure (STE) test method for hazard identification and labelling of eye irritating chemicals.
