Services

We deliver reliable environmental toxicity testing and related services including:

 

Ecotoxicological tests:

Bacteria Vibrio fischeri bioluminescence inhibition tests: Microtox acute toxicity test and Flash Assay (ISO 11348-3:2007 and ISO 21338:2010).

Algal growth inhibition test using Raphidocelis subcapitata (OECD 201).

Water flea Daphnia magna acute immobilisation test (OECD 202).

Water flea Daphnia magna reproduction test (OECD 211).

Common duckweed Lemna minor growth inhibition test (OECD 221).

Terrestrial plant test: seedling emergence and seedling growth test (OECD 208).

Genotoxicity assay in vitro:

Mutagenicity assessment by the Ames bacterial reverse mutation test using Salmonella typhimurium strains TA97a, TA98, TA100, TA102 and TA1535 (OECD 471).

Antimicrobial efficiency tests:

Antimicrobial susceptibility testing: bacteria or yeast growth inhibition tests (ISO 20776-1, EURL ECVAM DB-ALM Protocol No 33), respectively.

Antimicrobial efficiency testing of hard surfaces samples in dark, indoor ambient or UVA irradiation (modifications of ISO 27447 and ISO 22196).

Mammalian toxicity tests in vitro:

Chemical toxicity testing in vitro using mammalian cell lines: human alveolar epithelial cell line A549, human intestinal epithelial cell line Caco-2, human monocytic cell line THP-1 and murine fibroblast cell line Balb/c 3T3.

Physico-chemical tests:

Nanoparticle suspension analysis: hydrodynamic size and zeta potential of particles by Dynamic Light Scattering (Malvern Zetasizer).

Elemental analysis of solutions by the reflection X-ray fluorescence spectroscopy (TXRF) (Picofox S2).
