Вы искали: testorganismerne (Датский - Английский)

testorganismerne eksponeres for testkemikaliet i løbet af optagelsesfasen.
the test organisms are exposed to the test chemical during the uptake phase.

beskrivelse af observerede symptomer eller adfærdsændringer hos testorganismerne
description of observed symptoms or changes in behaviour of test organisms,

den første foderration blandes i jorden umiddelbart inden tilsætningen af testorganismerne.
the first food ration should be mixed with the soil immediately before the test organisms are added.

i elimineringsfasen overføres testorganismerne til beholdere med samme substrat, men uden testkemikaliet.
the elimination phase consists of transferring the test organisms to vessels containing the same substrate without the test chemical.

inden testorganismerne tilsættes, kontrolleres det, at testkemikaliet er ensartet fordelt i jorden.
the homogenous distribution of the test chemical into the soil should be verified before introducing the test organisms.

optagelses- eller eksponeringsfasen: det tidsrum, hvori testorganismerne udsættes for testkemikaliet.
the uptake or exposure phase is the time during which the test organisms are exposed to the test chemical.

dødelig koncentration (koncentration, hvor 50 % af testorganismerne dør inden for et bestemt tidsrum)
lethal concentration (concentration at which 50 % of test organisms show lethal effect in defined time)

virkningskoncentration (den koncentration, hvor 50 % af testorganismerne viser en virkning inden for et defineret tidsrum)
effect concentration (concentration at which 50 % of the organisms show an effect in defined time)

der etableres ideelt ligevægt mellem jord- og porevandfasen, inden testorganismerne tilsættes. en periode på fire dage ved 20 °c anbefales.
equilibrium between the soil and the pore-water phase should ideally be established before adding the organisms; a time period of four days at 20 °c is recommended.

elimineringsfasen: tidsrummet efter overførsel af testorganismerne fra et forurenet medium til et medium uden testkemikaliet, hvor elimineringen (eller nettotabet) af kemikaliet fra testorganismerne undersøges.
the elimination phase is the time, following the transfer of the test organisms from a contaminated medium to a medium free of the test item, during which the elimination (or the net loss) of the chemical from the test organisms is studied.
