Chemical bioaccumulation flow-through fish test
1 Scope
This standard specifies the chemical bioaccumulation flow-through fish test methods outlined, test preparation, test procedures, quality assurance and quality
Control, data and reports.
This standard applies to testing and evaluation lgPow value in a stable organic chemicals bioaccumulation between 1.5 to 6.0, also applies to
Testing and evaluation lgPow > highly lipophilic substances 6.0 bioaccumulation.
2 Terms and definitions
The following terms and definitions apply to this standard.
2.1
The concentration of the test organisms (or specific tissues) within certain test substance increases relative to the concentration of test substance in the medium.
2.2
Any time trial stage of absorption of the test organism (or specific tissues) in the concentration of the test substance concentration in the media for some of the test substance
The ratio. BCF also be dynamic equation rate constants (K1/K2) calculated directly, denoted BCFK.
2.3
The concentration of test substance in fish plotted curves and the corresponding time axis tends to parallel (change in amplitude ± 20%) state.
2.4
In the steady state, the test organisms (or specific tissues) ratio of the concentration of the substance and the concentration of the test medium within certain test substances.
2.5
Substance in octanol - than concentration of water reaches equilibrium two-phase medium. Usually expressed as Pow.
2.6
Test fish exposed to the medium containing the test substance in fish tissue or a specific rate of increase in the concentration of the test substance. Generally d-1
FIG.
2.7
After the transfer of the test fish from a medium containing the test substance to a medium free of the test substance, fish or a particular tissue concentration of the test substance
Reduced-rate. Usually expressed in d-1.
3 test substance information
a) solubility in water;
b) octanol - water partition coefficient (Pow);
c) hydrolysis resistance;
