ISO 16712:2005 specifies a method for the determination of acute toxicity to amphipods exposed over a period of 10 d to samples of contaminated marine or estuarine sediment, to chemical, industrial or municipal sludge or other solid wastes that may combine with marine or estuarine sediments, or to chemicals or preparations spiked into clean sediment.
