Name, CAS number, and

Provide reasoning why
substances were or were not selected for further investigation during
risk assessment.

Information on all analysed substances, even if the analytical
results were below the detection limits, is desired here. All substances
in the treated ballast water that were detected above the detection
limit are regarded as Relevant Chemicals and should be evaluated.
Chemical analysis results should be accompanied by a specification
of the applied Active Substance concentration, test conditions, characteristics
of the test water (temperature (T), pH, salinity, TOC, DOC, TSS),
sampling time, handling and storage of samples before analysis, and
analytical method.
If chemical analyses were performed during more than one
test run, the number of test runs should be stated and results should
be reported either in the form of mean values ± standard deviation
or minimum/maximum concentrations measured or individual measurements
for each test run. Analytical results should be provided for both
treated and control samples.
Reasoning should be provided, based on the documented state
of knowledge, on which basis the selection of substances for inclusion
in the chemical analysis was made, taking into account the chemical
reactivity of the Active Substance and other components of the respective
system. For instance, for chlorination systems, a minimal set of potentially
relevant substances can be found in document MEPC 59/2/13. A more
extensive list can be found in Annex II of the final report of the
R&D-project "Proposal for a harmonized Emission Scenario Document
on ballast water discharge" (MEPC 62/INF.19).
