Technical Approach to OECD 201

Overview:

The purpose of this test is to determine the effects of a substance on the growth of freshwater microalgae and/or cyanobacteria. Exponentially growing test organisms are exposed to the test substance in batch cultures over a period of normally 72 hours.

We offer 106 studies across 5 species including:

  • Pseudokirchneriella subcapitata,

  • Synechococcus leopoliensis,

  • Anabaena flos-aquae,

  • Desmodesmus subspicatus,

  • Navicula pelliculosa

Control types include DWC, DWC (WAF), Solvent Control

(THF), and Solvent Control (DMF).

Our team comprises proven experts in testing routine and problematic (hydrolytically unstable, highly sorptive, volatile, low solubility) materials and regularly develop novel methodologies, exposure systems and culture techniques to support bespoke testing strategies. We operate in modern GLP-compliant facilities striving to provide the highest quality service possible. We offer a comprehensive range of acute, chronic and bespoke aquatic ecotoxicology studies with a variety of test species and we can conduct testing to a variety of test guideline requirements.
