been shown to biodegrade to a high extent in an extended ready
biodegradation test using a standard OECD test guideline and is expected
to be inherently biodegradable. The principle transformation products (such
as mono-isotridecyl phthalate) are likely to be biodegradable.
also demonstrated a moderate extent of biodegradability in a simulation
test using river water, and moderate degree of removal in a wastewater
treatability test based on a DT50of <1 day. These data are
consistent with modelled data that suggest DTDP will be largely
eliminated in a STP.
not available to assess the biodegradability of DTDP in sediment.
However, the monoester of DIDP (mono-isodecyl phthalate) demonstrated an
average half-life of 25 hours in marine sediments. Because the formation
of the monoester occurs as the first step in the biotic degradation of
DIDP and because this step does not appear to be rate limiting, as
evidenced by the high extent of biodegradation demonstrated by DIDP in a
ready test, the degradation of the diester in sediment is expected to
occur at a similar high rate. Because
Di-isodecyl phthalate ester (DIDP) is an analog to DTDP, DTDP is
expected to biodegrade in sediment at approximately the same rate as was
exhibited by DIDP.
not available to assess the biodegradability of DTDP in soil. However,
data for an earthworm toxicity test suggest DINP, an analog to DTDP,
would have a half-life in soil of approximately 51 days. Based
on the extent of biodegradability measured using various test
procedures, DTDP and its degradation products are expected to biodegrade
at a moderate rate under simulated conditions and in sediment and soil.
