i) Average-30 values Post-DeSOx. Samples taken before any dilution for pH adjustment.
ii) Sum of average-30 values of single PAHs.
iii) Values shown in this table were calculated, for better comparability, from the originally sulphate measurements (SO4?- mg/L) reported in Table A-4 of that study
iv) Values shown in this table were calculated, for better comparability, from the originally reported values in NO3-N and NO„-N, respectively, from that study.
v) Instead, total nitrogen was measured. Results range between 0.22 — 0.56 mg N/L in OL and 86 - 120 mg N/L in CL.
vi) Measured parameter was Hydrocarbon Oil Index (HOl) according to standard ISO 9377-2.
vii) Reported value corresponds to the sum of all aliphatic (Cs-Cao) and aromatic (C10-C36) fractions measured, in the report called Total Hydrocarbons.
viii) Reported value corresponds to the sum of benzene —- C3s, in the report called Total Hydrocarbons.
ix) Samples taken before any dilution for pH adjustment.
x) Reported value corresponds to the sum of hydrocarbon fractions (C10-Cao).
xi) Values taken from the Table 6 column “Washwater before discharge” — “IMO (no dilution)” of the referenced article. Samples were taken after water treatment (particle removal) and prior
any dilution.
