SUMMARY:

Air pollution is a long-standing issue, and the constant increase in demand for goods and services has led to a rise inair quality degradation, resulting in the creation of policies for pollution control and mitigation. Industrial and portemissions are significant contributors to the release of atmospheric pollutants, particularly when concentrated in thesame area, such as in Industrial Port Complexes. However, despite the widely known adverse effects, air qualitylegislation and monitoring in Brazil are still inadequate, especially in the North and Northeast regions of the country. Inthe entire state of Pernambuco, there are only five active air quality monitoring stations and one deactivated station,all located in the vicinity of the Suape Industrial Port Complex (SIPC). These issues highlight the need for alternativemonitoring approaches, such as the implementation of atmospheric modeling systems. Considering theaforementioned challenges, the objective of this study was to diagnose the air quality in the vicinity of SIPC andassess the use of an atmospheric model as an alternative for broader monitoring. To achieve this, data from fivepollutants (CO, PM10, NO2, O3, and SO2) were analyzed at five air quality monitoring stations (CPRH, Cupe, Gaibu,IFPE, and Ipojuca) located in the Metropolitan Region of Recife, Pernambuco, between 2017 and 2021. To assesslocal air quality, the obtained concentrations were compared with the final standard (FS) established in ConamaResolution No. 491/2018. Meteorological data were also applied to identify the predominant wind directionsthroughout the study period and during instances when PFs were exceeded. Additionally, the Hysplit (Hybrid Single-Particle Lagrangian Integrated Trajectory) atmospheric model was employed, using backward trajectory simulationsand cluster analysis to identify possible pollutant sources capable of generating the secondary pollutant O3. Based on the applied methods, it was observed that, in addition to the limited number of monitoring stations in the state, theprovided information is incomplete, and the majority of monitored concentrations did not exceed the FS. Among theinstances of FS exceedance (221 events), PM10 exceeded the limit the most (132 days). According to wind patterns,it is likely that the exceedances at all studied stations are related to industrial and port emissions from SIPC. Ozonewas another pollutant of concern, with 214 hourly moving averages above the FS. Through cluster analysis ofbackward trajectories, it was observed that 89% of air trajectories originated from the ocean, and 11% from the SIPCarea, potentially influenced by ship-emitted NOx and petrochemical-related VOCs. Based on the obtained results, itcan be concluded that both industrial and port activities conducted at SIPC are significant potential sources of airpollution.
