AgroChemex - Algae

Studies can be conducted to assess the inhibitive effect a chemical has on the growth of freshwater algal species. The study can be designed to comply with regulatory guidelines.

Exponentially growing algae cells are exposed via growth media to the test item at a range of concentrations. The test is conducted under static conditions.  Increase of biomass is assessed and recorded, using cell counts or surrogate measurements, at 24 hourly intervals for typically 72 hours.

The data can be used to determine ECx, LOEC and NOEC, with relation to  specific growth rate and yield.

Measurements of pH and temperature are taken; environmental conditions can be maintained within the requirements of the test in one of our controlled environment rooms. Microscopic observations to determine the health status are made at the beginning and end to observe any abnormal appearance of algae caused by the test substance at the end of the test.
