should be noted that the test substance is not considered as posing a
hazard to the aquatic environment.
test substance, REACTIVE ORANGE F08-0314, is a solid under all
environmental conditions and is highly soluble in water (417 g/L). It is
expected to have a low volatility (based on a melting point >400°C) and
it is expected to have a low affinity for soil / sediment (based on the
low Log Kow value <-4.5). As such, any environmental release will result
in virtually all of the substance compartmentalising into water
compartments, with little release directly to atmosphere or
compartmentalising to soil/sediment compartments.
potential exposure to the environment is predicted to result in rapid
redistribution to water; due to its low volatility, high water
solubility and partitioning values it is indicated that the majority of
the substance would eventually partition to water rather than to soil
and sediment should it be released to the environment.
Level III fugacity model was conducted in the US EPA EPISUITE (Mackay,)
which assumes steady-state but not equilibrium conditions. The
Level III model in EPI Suite predicts partitioning between air, soil,
sediment and water using a combination of default parameters and various
input parameters. This
model has been used to calculate the theoretical distribution of the
highest % component substance between four environmental compartments
(air, water, soil, sediment) at steady state in a unit world.
is detailed to be:
- Air 1.17e-009
- Water 6.01%
- Soil 93.7%
- Sediment 0.249
proposed that although the majority of the substance distributes to the
soil compartments within the model, the high solubility in water
indicates that the substance is more likely to distribute to water – e.
g. soil pore water.
ORANGE F08-0314 displays low biodegradability in that it achieved 1.2%
biodegradation in a 28-day closed bottle test and 0% biodegradability in
a 28 day inherent biodegradability test. This indicates that it is
unlikely to achieve a half life of less than 40 or 60 days within fresh
water attributed to ready biodegradation alone. The substance undergoes
hydrolysis at environmentally relevant pH’s (t1/2 = 87 hours at pH7),
indicating the potential for significant removal by
on direct phototransformation in water are not available but it is
assumed on the basis of chemical structure and nature of use that the
substance is not degraded by direct photolysis. It is concluded,
therefore, that abiotic processes would contribute significantly to the
depletion of the substance within the environment.
ORANGE F08-0314 has a measured log Pow of <-4.5. This value indicates
that possible bioaccumulation in the food chain is not anticipated.
Given the fact that the substance is subject to hydrolysis at
biologically relevant pH’s, it is anticipated that bioaccumulation of
the substance itself would not occur, as hydrolytic effects in
association with metabolic effects would result in removal of the
to soil is deemed to be low, based on the very low Kow value and high
water solubility. Such a low potential indicates that the substance is
unlikely to bind tightly to soils and sediments and instead partition
almost exclusively to water. As such, significant exposure related
effects to sediment and soil dwelling organisms are considered to be
on its high water solubility and low partition coefficient, it can be
concluded that it is unlikely that REACTIVE ORANGE F08-0314 could
potentially be persistent within the environment. As such, significant
contact with organisms via the food chain is not anticipated and can be
considered to be minimised.
REACTIVE ORANGE F08-0314 demonstrates low acute toxicity in mammalian
studies therefore in the event of exposure to environmental organisms,
effects due to secondary poisoning can be excluded.
studies have all been ranked reliability 1 according to the Klimisch et
al system. This ranking was deemed appropriate because the studies were
all conducted to GLP in compliance with recognised guidelines.
