AB The main aim of this work was to measure the influence of the volume of shipping over the Sulphur dioxide (SO2)concentration in the air pollution in two monitoring stations located at Algeciras city and Alcornocales Parkdeveloping the same analysis in these two locations. The target is to demonstrate the assumption that Algeciras ismore affected by SO2 than Alcornocales Park which is 30 km far away from Algeciras Port. A multiple regressionapproach has been applied using wind data: wind direction (degrees) and wind speed (km/h) recorded in two weatherstations, together with the volume of the gross tonnage per hour (GT/h) of vessels in the Bay of Algeciras to estimateSO2 concentration values in the two stations Algeciras and Alcornocales. The database contains records of hourlysamples of these variables during the year 2019. Different artificial neural networks (ANNs) models were comparedand the results showed that SO2 in Algeciras station could be better explained than the same pollutant in Alcornocalesstation. On the other hand, ANNs produced better results than linear models which means that nonlinear models fitbest the data. A cross-validation procedure has been applied in order to assure the generalisation capabilities of thetested models. The results showed that in Algeciras a more reliable estimation could be done reaching a correlationestimation between the model and the target (real) values of SO2. This fact highlights the major influence of maritimetransport in the Bay of Algeciras.
