Flow-through fish test static fish test
1 Scope
This standard specifies the flow-through fish test fish static test definitions of terms, test methods and data processing and report the results.
This standard applies to discrimination bioaccumulation characteristics of chemicals, assessment of test substance in fish enrichment capability, determined to have a low, medium enrichment
Characteristics (BCF < 103) of the test substance BCF.

3 Definition of Terms
The following terms and definitions apply to this standard.
3.1
Biological aggregation
Test substance in organs (especially in the tissue) and increasing concentrations of substances in the environment related to the concentration.
3.2
Bioconcentration factor (BCF)
At steady state, the concentration of the test fish and test water to the test substance concentration ratios.
3.3
Octanol dissolution rate in water at equilibrium. Bio-accumulation potential of aquatic organisms logarithm of Pow to mark.
3.4
The absorption rate constant (K1)
Fish in fish exposed to the determination of test substance concentration of a substance when the growth rate of the digital representation (unit. day-1).
3.5
Release rate constant (K2)
The fish species from the environment is transferred to the concentration of substances in the environment after fish in the test substance-free assay comprising measuring the rate of decrease
Digital Expression (unit. day-1).
3.6
Release phase
The fish is measured from a substance containing an environment free of the test substance is transferred to the environment, the substance of foreign release assay stage.
4 test equipment and solutions
4.1 Test Instrument
The test to avoid the use of any part will be dissolved, absorbed, or have an adverse effect on the fish of the instrument. It can be used with rectangular or cylindrical
Chemically inert material prepared instruments, have a certain volume and loading rate. Use of soft plastic tubing should be minimized. PTFE can be used
