Abstract

São José do Rio Preto is a city in the interior of the state of São Paulo greatly impacted by the burning of sugar cane, in addition, data collected by DATASUS between the years 2018 and 2021, reveal a worrying scenario regarding diseases of the household appliance among city residents.The objective of this work is the determination of polycyclic aromatic hydrocarbons and derivatives (oxy and nitro-HPA) in samples of fine particulate matter, collected in the dry period. The carcinogenic and mutagenic risk rates due to exposure through inhalation, the sources, will also be calculated through the profiles presented and the calculation of diagnostic reasons and principal components analysis.The HYSPLIT model will also be used to investigate air mass transport arriving in the city. The results will be compared with hospitalizations and data provided by DATASUS, in addition to identifying possible relationships between pollution and health.
