Two new studies are included in this section of the dossier. The first is a radiolabelled study conducted on bluegill sunfish which includes both a bioaccumulation and depuration phase. The second study was conducted on a freshwater species (killifish) and a marine species (blue mussel) but only includes the bioaccumulation phase. The results from both studies indicate that 1,1,1-trichloroethane does not bioaccumulate in either freshwater or marine species.
Barrows et al 1980 conducted a
closed system follow-through study on Bluegill Sunfish over 28 days
using radiolabelled material. Experimental results show that 1,1,1-trichloroethane
does not bioaccumulate in fish and when exposure ceases residues in fish
are lost within 24 hours. The BCF (quotient of the mean measured
residues of the compound in fish tissues (whole body) during the
equilibrium period divided by the mean measured concentrations of the
compound in exposure water) was 9 and the DT50 in fish tissues ws 1.0
day. The second study report (Saisho et al 1993) includes data on
freshwater fish and on marine mussels. The results show that 1,1,1-trichloroethane
did not bioaccumulate in either trophic group.
