Over deze norm
This International Standard 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: a) samples of contaminated whole fresh water sediment; b) chemical, industrial, or municipal sludge, or other solid wastes that may combine with fresh water sediments; or c) chemicals or preparations spiked into clean sediment. This International Standard is applicable to the testing of sediment samples from the fresh water environment. Hyalella azteca can be used in the testing of brackish waters up to a maximum of 15 ‰, with careful acclimation. This International Standard 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.
