< div class=" SectionLevel2" > < p class=" subsec1 cdone2" > < span class=" Head3 cdone" > 1.1< / span> Deze gids behandelt procedures voor het verkrijgen van laboratoriumgegevens over de nadelige effecten van mogelijk verontreinigd sediment, of van een testmateriaal dat experimenteel wordt toegevoegd aan verontreinigd of niet-verontreinigd sediment, op mariene of estuariene infaunale polychaeten gedurende een blootstelling van 10 dagen of 20 tot 28 dagen. Deze procedures zijn nuttig voor het testen van de effecten van verschillende geochemische kenmerken van sedimenten op mariene en estuariene polychaeten en kunnen worden gebruikt om de toxiciteit van sedimenten voor andere infaunale taxa te beoordelen, hoewel aanpassingen van de procedures die geschikt zijn voor de geteste soort nodig kunnen zijn. Procedures voor de 10-daagse statische test worden beschreven voor < span style=" font-style:italic font-weight:normal " class=" overriddenformat" > Neanthes arenaceodentata < / span> en < span style=" font-style:italic font-weight:normal " class=" overriddenformat" > Alitta virens < / span> < span style=" font-style:normal " > < span class=" footnote-link" > 2< / span> < / span> (voorheen < span style= " font-style:italic font-weight:normal " class=" overriddenformat" > Nereis virens< / span> en < span style=" font-style:italic font-weight:normal " class=" overriddenformat" > Neanthes virens< / span> ) en voor de 20 tot 28 dagen durende statische vernieuwing van sedimenttoxiciteit voor < span style=" font-style:italic font-weight:normal " class=" overriddenformat" > N. areaceodentata< / span> .

< / div> < div class=" SectionLevel2" > < p class=" subsec1 cdone2" > < span class=" Head3 cdone" > 1.2< / span> Aanpassingen van deze procedures kunnen geschikt zijn voor andere testprocedures voor sedimenttoxiciteit, zoals doorstroomtests of gedeeltelijke levenscyclustests. De methoden die in deze gids worden beschreven, zouden ook nuttig moeten zijn voor het uitvoeren van sedimenttoxiciteitstests met andere aquatische taxa, hoewel aanpassingen nodig kunnen zijn. Andere testorganismen kunnen andere soorten polychaeten, schaaldieren en tweekleppigen zijn.

< / div> < div class=" SectionLevel2" > < p class=" subsec1 cdone2" > < span class=" Head3 cdone" > 1.3 < / span> Andere wijzigingen van deze procedures kunnen geschikt zijn voor speciale behoeften of omstandigheden. Hoewel het gebruik van geschikte procedures belangrijker is dan het volgen van voorgeschreven procedures, zullen de resultaten van tests die zijn uitgevoerd met ongebruikelijke procedures waarschijnlijk niet vergelijkbaar zijn met die van veel andere tests. Vergelijkingen van de verkregen resultaten met gewijzigde en ongewijzigde versies van deze procedures kunnen nuttige informatie opleveren over nieuwe concepten en procedures voor het uitvoeren van sedimenttesten met infaunale organismen.

< / div> < div class=" SectionLevel2" > < p class= " subsec1 cdone2" > < span class=" Head3 cdone" > 1.4< / span> Deze procedures zijn van toepassing op sedimenten die zijn verontreinigd met de meeste chemicaliën, afzonderlijk of in formuleringen, commerciële producten en bekende of onbekende mengsels. Deze procedures kunnen met de juiste aanpassingen worden gebruikt om sedimenttoxiciteitstests uit te voeren op factoren zoals temperatuur, zoutgehalte, opgeloste zuurstof (DO) en natuurlijke sedimentkenmerken (bijvoorbeeld deeltjesgrootteverdeling, organisch koolstofgehalte en totale vaste stoffen). Deze procedures kunnen ook worden gebruikt om bioconcentratietests en in situ tests uit te voeren, en om de toxiciteit te beoordelen van mogelijk verontreinigde veldsedimenten, of van materialen zoals rioolslib, oliën, deeltjes en oplossingen van toxische stoffen die aan sedimenten zijn toegevoegd. Een mediane dodelijke concentratie (LC50) of mediane subletale effectconcentratie (EC50) van toxische stoffen of van sterk verontreinigd sediment vermengd met niet-verontreinigd sediment kan worden bepaald. Materialen die hechten aan sedimentdeeltjes of opgelost zijn in interstitieel water kunnen worden getest.

< / div> < div class=" SectionLevel2" > < p class=" subsec1 cdone2" > < span class=" Head3 cdone" > 1.5< / span> De resultaten van 10-daagse toxiciteitstests met verontreinigde sedimenten kunnen worden gerapporteerd als een LC50 als een reeks concentraties wordt getest of als een percentage mortaliteit ten opzichte van een controle- of referentiesediment. De resultaten van 20 tot 28-daagse toxiciteitstesten met verontreinigde sedimenten kunnen worden gerapporteerd als een LC50 als een reeks concentraties wordt getest of als een percentage mortaliteit of groei ten opzichte van een controle- of referentiesediment.
