Both geolocalization and description of stations from the Container Terminal from San-Pedro Port Area (CTSP) were presented in [8] . Concerning Ebrié Lagoon, the geographic coordinates of study stations are presented in Table 1. Sampling Stations P1, P2, P3 and P4 are located in the lagoon between the EOLIS fruit terminal and the National Customs School. Sampling Stations P5, P6, P8, P9 and P10 are located in the lagoon between the ADDOHA lagoon city, the Municipal High School of Attécoubé, Abobo-Doumé Beach and the Abobo-Doumé Lagoon station. Sampling Station P7 is located between Stations P4 and P9.

The samples used for the study of phytoplankton were obtained 1) from the remaining volume of sample taken using the Van Dorn bottle for the analysis of nutrient salts in Stations S1, S2, S3, S4, S5, S6, S7, S8, S9 and S10 between 8 a.m. and 3 p.m. for the Container Terminal from San-Pedro Port Area (CTSP) and 2) using a plastic bottle of 1-liter capacity at 0.5 m from the lagoon water body in 10 sampling Stations P1, P2, P3, P4, P5, P6, P7, P8, P9 and P10 between 8 a.m. and 3 p.m. The TCSP samples were filtered through a 20 µm diameter plankton net, stored in 100 mL pillboxes and then fixed in 5% formalin for subsequent analysis in the laboratory. In total, 27 samples including 17 samples for the TCSP and 10 samples for the Ebrié Lagoon were collected from the surface water sampling. Observations and counting of organisms were carried out using an Optika-type inverted microscope. The observed taxa were photographed using a Sony Cyber-shot DSC-W800 type camera. The methodology of [9] was used for the preparation of diatoms. The identification of the taxa observed was carried out using general and specific identification books and keys.

Concerning the CTSP samples, the counting of all the organisms was made using the sedimentation cups of volume 3.4 mL, 5 mL, 10 mL, and 25 mL from the inverted microscope according to the method of [10] modified (standard NF EN 15204) by [11] . Replica counts of organisms were carried out on all samples except for samples from Stations S1, S2, S3, S5, S6 and S7 of the second mission. For this mission, 3.4 mL sedimentation cups were used for the samples from Stations S1 and S6, those of 10 mL were used for the samples from Stations S2, S5 and S7. The samples from the Station S3 were counted using the 5 mL volume sedimentation dish. Counting replicas of samples from the first mission were made with 3.4 mL and 5 mL sedimentation cups for samples from Stations S2, S3, S7, S9 and S10. The 5 mL and 10 mL sedimentation cups were used for the samples from Stations S1 and S4. The samples from Stations S5, S6 and S8 were counted using 5 mL and 25 mL sedimentation cups. The sample from the Station S4 of the second mission was counted with 3.4 mL and 25 mL cups. The samples from the Ebrié Lagoon, sub-samples were made in Petri dishes for the observation and counting of the taxa contained in 1 liter of water sample.

The results are expressed in number of individuals per milliliter for the CTSP samples and per liter for the samples from the Ebrié Lagoon.

A total of 324 taxa were collected from fresh and brackish waters studied (Table 2). The Container Terminal from San-Pedro Port Area (CTSP) was characterized by 274 taxa while Ebrié Lagoon was represented by 82 taxa belonging to Cyanobacteria (11 taxa), Euglenophyta (34 taxa), Chlorophyta (31 taxa), Dinophyta (80 taxa), Cryptophyta (2 taxa), Chrysophyta (12 taxa), Rhodophyta (2 taxa), Ochrophyta (1 taxon) and Bacillariophyta (151 taxa).
