EC number: 701-173-1
CAS number: -
test substance is covered by the category approach of methylenediphenyl
diisocyanates (MDI). Hence, data of the category substances can be used
to cover this endpoint. The read-across category justification document
is attached in IUCLID section 13. It is important to note that the MDI
category approach for read-across of environmental and human hazards
between the MDI substances belonging to the MDI category is work in
progress under REACH. Therefore the read-across document should be
considered a draft.
Two separate short-term toxicity studies (van der Hoeven et al, 1992)
are available with terrestrial organisms for polymeric MDI. For the
earthworm Eisenia fetida, tested according to OECD 207, a
14d-EC50 of 1000 mg/kg soil (d.w.) was obtained. For the plants Avena
sativa and Lactuca sativa, tested according to OECD 208,
14d-EC50 of 1000 mg/kg soil (d.w.) values were obtained. The values may
be considered for the derivation of a PNEC soil.
