hazardous substances (aquatic environment)
2.2.9.1.10.1
General definitions
2.2.9.1.10.1.1
Environmentally hazardous substances include, inter alia, liquid
or solid substances pollutant to the aquatic environment and
solutions and mixtures of such substances (such as preparations
and wastes).
For the purposes of
2.2.9.1.10,
"substance" means chemical
elements and their compounds in the natural state or obtained by
any production process, including any additive necessary to
preserve the stability of the product and any impurities deriving
from the process used, but excluding any solvent which may be
separated without affecting the stability of the substance or
changing its composition.
2.2.9.1.10.1.2 The aquatic
environment may be considered in terms of the aquatic organisms
that live in the water, and the aquatic ecosystem of which they
are part10. The basis, therefore, of the
identification of hazard is the aquatic toxicity of the substance
or mixture, although this may be modified by further information
on the de gradation and bioaccumulation behaviour.
10 This does not
address aquatic pollutants for which there may be a need to
consider effects beyond the aquatic environment such as the
impacts on human health etc.
2.2.9.1.10.1.3 While the
following classification procedure is intended to apply to all
substances and mixtures, it is recognised that in some cases,
e.g. metals or poorly soluble inorganic compounds, special
guidance will be necessary11.
11 This can be found in
Annex 10 of the GHS.
2.2.9.1.10.1.4 The
following definitions apply for acronyms or terms used in this
section:
- BCF: Bioconcentration
Factor;
- BOD: Biochemical Oxygen
Demand;
- COD: Chemical Oxygen Demand;
- GLP: Good Laboratory
Practices;
- EC50: the effective
concentration of substance that causes 50% of the maximum
response;
- ErC50:
EC50 in terms of reduction of growth;
- Kow: octanol/water
partition coefficient;
- LC50 (50% lethal
concentration):
the concentration of a substance
in water which causes the death of 50% (one half) in a group of
test animals;
- L(E)C50:
LC50 or EC50;
- NOEC: No Observed Effect
Concentration;
- OECD Test Guidelines: Test
guidelines published by the Organization for Economic Cooperation
and Development (OECD).
2.2.9.1.10.2
Definitions and data requirements
2.2.9.1.10.2.1 The basic
elements for classification of environmentally hazardous
substances (aquatic environment) are:
- Acute aquatic toxicity;
- Potential for or actual
bioaccumulation;
- Degradation (biotic or abiotic)
for organic chemicals; and
- Chronic aquatic toxicity.
2.2.9.1.10.2.2 While data
from internationally harmonised test methods are preferred, in
practice, data from national methods may also be used where they
are considered as equivalent. In general, it has been agreed that
freshwater and marine species toxicity data can be considered as
equivalent data and are preferably to be derived using OECD Test
Guidelines or equivalent according to the principles of Good
Laboratory Practices (GLP). Where such data are not available,
classification shall be based on the best available data.
2.2.9.1.10.2.3 Acute aquatic
toxicity shall normally be determined using a fish 96 hour
LC50 (OECD Test Guideline 203 or equivalent), a
crustacea species 48 hour EC50 (OECD Test Guideline
202 or equivalent) and/or an algal species 72 or 96 hour
EC50 (OECD Test Guideline 201 or equivalent). These
species are considered as surrogate for all aquatic organisms and
data on other species such as Lemna may also be considered if the
test methodology is suitable.
2.2.9.1.10.2.4
Bioaccumulation means net result of uptake, transformation
and elimination of a substance in an organism due to all routes
of exposure (i.e. air, water, sediment/soil and food).
The potential for
bioaccumulation shall normally be determined by using the
octanol/water partition coefficient, usually reported as a log
Kow determined according to OECD Test Guideline 107 or
asjoint-stocktax-authorityvid
