Water quality - Determination of toxicity of fresh water sediments using Hyalella azteca

PUBLISH DATE 2013
ISO 16303:2013

ISO 16303:2013 specifies a method for the determination of toxicity to young Hyalella azteca in whole sediment based on survival and growth inhibition after 14 d and/or 28 d.

The method is applicable to:

  • samples of contaminated whole freshwater sediment,
  • chemical, industrial, or municipal sludge, or other solid wastes that may combine with freshwater sediments, and
  • chemicals or preparations spiked into clean sediment.

ISO 16303:2013 is applicable to the testing of sediment samples from the freshwater environment. Hyalella azteca can be used in the testing of brackish waters up to a maximum of 15 ‰, with careful acclimation.

ISO 16303:2013 is not applicable to the testing of sediment samples from the marine and estuarine environment with a salinity of > 15 ‰.

This method is a 14 d and/or 28 d survival-and-growth test applicable to the sediment sample types described above.
