Currently there is a great global concern due to the increase of compounds in ecosystems from many products that are used daily in many areas, and the concern increases since these compounds called emerging pollutants (EC) are affecting ecosystems in general to the living organisms and microorganisms. In this work, 9 CE were analyzed in samples of water, suspended material and sediments from three aquatic ecosystems of the department of Córdoba-Colombia, the samples were taken in two climatic seasons of rain and drought, the risk analysis was carried out taking into account the previous concentration without effect and finally the analysis of principal components and the distribution was obtained by using the statistical program R studio. The results obtained in this study show us the presence of these ECs in these ecosystems as well as some of them in concentrations that could be affecting the ecosystem. The maximum concentration found in the water samples was in the Cispatá bay in the first sampling corresponding to 15354.15 ng / L of Ibuprofen, for the suspended material samples it was 251.69 ng / g of Triclosan detected in the first sampling in the bay. of Cispatá in the Zarapa channel and for the sediments the maximum concentration was found in After Playa Blanca with 164.74 ng / g of NPX. In the analysis of principal components, a maximum correlation between the EC of 40.9% was determined in the Cispatá bay corresponding to component 1 of said analysis. For the ecological risk analysis, it was found that in the rainy season, that is, the first sampling the Cispatá Bay in the estuarine zone, the Ayapel swamp in the vast majority of its points and the Lorica swamp 3 points were at high risk. For the second sampling in the dry season, the Cispatá bay decreased the risk to almost zero at all points, The Ayapel swamp the risk remained high for all the points and for the Lorica swamp it was high at three sampling points. Regarding the distribution, the great influence of drugs such as NPX, IBP and GMF in the bay of Cispatá stands out, in the swamps the presence of hormones such as 17alpha-Ethinyl estradiol and Progesterone can be seen more, as well as the antiepileptic Carbamazepine and the plasticizer BPA. These results reflect that many of the ECs are reaching ecosystems and in concentrations that could be affecting organisms and ecosystems in general.
