Water quality - Guidelines for algal growth inhibition tests with poorly soluble materials, volatile compounds, metals and waste water

ISO 14442:2006 provides procedures, not covered by the methods described in ISO 8692 and ISO 10253, for testing difficult substances for inhibition of algal growth. The main subjects covered by ISO 14442:2006 are the methods for preparing the test substance for testing and the procedures needed to carry out an appropriate test. The following test substances are covered by this guideline: poorly soluble pure organic compounds; poorly soluble mixtures of organic substances; poorly soluble inorganic materials; volatile substances; waste waters and environmental samples containing water and sediments; coloured and/or turbid samples; compounds of heavy metals. The following methods of addition are covered: direct; dispersion; water-soluble and water-accommodated fractions. Some guidelines related to the analytical procedures and to the interpretation of the results have been included.
