Evidence of the biodegradation potential for
1,2-Benzenedicarboxylic acid, di-C6-10-alkyl esters can be observed with
the results from the OECD 301B ready biodegradability studies. After 29
d 87 % was biodegraded. The 10 -day window is reached because during 10
d > 60 % was biodegraded. Therefore 1,2-Benzenedicarboxylic acid,
di-C6-10-alkyl esters is regarded as readily biodegradable. Because the
substance can be regarded as readily biodegradable, the results indicate
that the substance is not persistent (P).
The octanol water partition coefficient of
the substance (Log Kow > 8.2) suggests the potential for the substance
to be bioaccumulative. In general, at log Kow values between 4 and 5,
log BCF increases linearly with log Kow. At high log Kow (> 6), a
decreasing relationship between the two parameters is observed and for
very hydrophobic chemicals, reduced uptake due to the increasing
molecular size may occur. The aquatic BCF of a substance is probably
lower than 2000 L/kg if the calculated log Kow is higher than 10. BCF
has been calculated using the computer program BCFBAF (v3.00). BCF has
been calculated using the computer program BCFBAF (v3.00). It is
predicted that the substance has BCF of 1033 L/kg wet weight. The
substance is not bioaccumulative. For other, structurally similar
materials assessments have been conducted within the EU. A phthalate
ester with branched alcohol chains (as opposed to linear alcohol chains)
has undergone risk assessment (European Union Risk Assessment Report on
1,2-benzenedicarboxylic acid, di-C9-11-branched alkyl esters, C10-rich
and di-“isodecyl” phthalate, Final Report, 2003).The report considers
bioaccumulation in aquatic organisms and cites a single test where a BCF
of < 14.4 was determined for fish (Cyprinus carpio) according to OECD
test guideline No. 305C. Other studies showed BCF’s in the same order of
magnitude. All available data indicate that the estimated BCF for the
test material is likely to reflect the real bioaccumulation and
therefore the substance is considered not to be bioaccumulative (B).
Aquatic toxicity tests do not indicate the
substance meets the criteria to be regarded as toxic (T). Furthermore
1,2- Benzenedicarboxylic acid, di-C6-10-alkyl esters is not classified
into carcinogenic, germ cell mutagenic, or toxic for reproduction or
