<p>ISO 16303:2013 specifies a method for the determination of toxicity to young <em>Hyalella azteca</em> in whole sediment based on survival and growth inhibition after 14 d and/or 28 d.</p>
<p>The method is applicable to</p>
<p>a) samples of contaminated whole freshwater sediment,</p>
<p>b) chemical, industrial, or municipal sludge, or other solid wastes that may combine with freshwater sediments, and</p>
<p>c) chemicals or preparations spiked into clean sediment.</p>
<p>ISO 16303:2013 is applicable to the testing of sediment samples from the freshwater environment. <em>Hyalella azteca</em> 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 ?.</p>
<p>This method is a 14 d and/or 28 d survival-and-growth test applicable to the sediment sample types described above.</p>
