Annotation of standard text ČSN EN ISO 11268-2 (836456):

Tento dokument specifikuje jednu z metod pro hodnocení funkce půdního prostředí a stanovení účinků půdních kontaminantů a chemických látek na reprodukci Eisenia fetida/Eisenia andrei. Zkušební živočichové jsou vystaveni působení látek, které přijímají pokožkou a zažívacím traktem. Tato chronická zkouška je použitelná pro půdy a půdní materiály neznámé kvality, např. z kontaminovaných stanovišť, upravených půd, půd po remediaci, ze zemědělských nebo jiných stanovišť, a pro odpady. Tato metoda je navržena hlavně pro stanovení účinků půdních kontaminantů a chemických látek na reprodukci Eisenia fetida/Eisenia andrei. Jsou uvedeny také technické informace o tom, jak používat Eisenia fetida/Eisenia andrei pro zkoušení chemických látek v tropických podmínkách (viz příloha A). Nakonec tato metoda zahrnuje také technické informace o tom, jak ji používat s dalšími environmentálně relevantními druhy žížal: např. Dendrodrilus rubidus a Aporrectodea caliginosa (viz přílohy B a C). Tato metoda není použitelná pro zkoušení látek, jejichž rozdělovací koeficient voda/vzduch je větší než jedna, nebo látek, jejichž tlak par při 25 °C je vyšší než 300 Pa. U této metody se nebere v úvahu perzistence látky během zkoušky. .
