Bibliography

Describes a method for the determination of the growth inhibition of unicellular green algae by substances and mixtures contained in water or by waste water.

This International Standard specifies a method for the determination of the growth inhibition of unicellular green algae by substances and mixtures contained in water or by waste water. This method is applicable for substances that are easily soluble in water.

With modifications to this method, as specified in ISO14442 and ISO5667-16, the inhibitory effects of poorly soluble organic and inorganic materials, volatile compounds, heavy metals and waste water can be tested.

A rapid algal growth inhibition screening test for waste water is described in AnnexA.

An alternative test procedure with algae from algal beads, with direct measurement of algal growth in spectrophotometric cells, is described in AnnexB.
