Description of key information
Additional information
By data of the supporting substances (C20/22 ATQ, if not specified otherwise) three terrestrial trophic levels are covered with the available tests
1) AUTOTROPHS (Producer)
Terrestrial plant studies (9 different species) read across from Quat DHTDMAC (CASNo. 61789-80-8) with NOEC between 40 and 1400 mg/kg dw (median value is 1000 mg/kg dw.)
2) HETEROTROPHS (Consumer)
Earthworm (Eisenia fetida), OECD 207 (acute) & OECD 222 (chronic), Collembola ISO 11267 (chronic)
3) DETRITIVORS (Decomposer)
Soil microorganisms, OECD 216 (chronic)
In Table 6.3 the different test results for the terrestrial compartment are given.
