Abstract

ECHOES OF THE OIL SPILL OF 2019: ASSESSMENT OF THE PRESENCE OF PAH AND BTEX IN PRODUCTS FROM FISHING. The 2019 oil spill in Brazil caused widespread contamination in the Brazilian coast, posing risks to both animal and human health through seafood consumption. Therefore, this study aimed to evaluate seafood samples from different locations impacted by the oil spill. For this purpose, 44 samples underwent extraction processes for the determination of polycyclic aromatic hydrocarbons (PAH) and benzene, toluene, ethylbenzene, and xylene (BTEX). The BTEX compounds were undetected above the limit of detection (LOD) of 0.02 µg g-1 of wet mass. The LOD and limit of quantification (LOQ) for the PAH were 2 and 5 ng g-1,... (More)

ECHOES OF THE OIL SPILL OF 2019: ASSESSMENT OF THE PRESENCE OF PAH AND BTEX IN PRODUCTS FROM FISHING. The 2019 oil spill in Brazil caused widespread contamination in the Brazilian coast, posing risks to both animal and human health through seafood consumption. Therefore, this study aimed to evaluate seafood samples from different locations impacted by the oil spill. For this purpose, 44 samples underwent extraction processes for the determination of polycyclic aromatic hydrocarbons (PAH) and benzene, toluene, ethylbenzene, and xylene (BTEX). The BTEX compounds were undetected above the limit of detection (LOD) of 0.02 µg g-1 of wet mass. The LOD and limit of quantification (LOQ) for the PAH were 2 and 5 ng g-1, respectively. The range of recovery of PAH obtained from spiking was 39 ± 15.8 to 84 ± 5%. The concentration of PAH in the samples ranged from < LOQ to 17.5 ng g-1. Results suggested higher contamination levels in samples collected in Rio de Janeiro, with quantifications for 11 of the evaluated PAH. Benzo[a]pyrene and dibenzo[a,h]anthracene, both potentially carcinogenic, were found in 32 and 14% of samples, respectively. Therefore, additional coastal monitoring is advised to ensure seafood safety, given the potential PAH carcinogenicity, which could strain the Brazilian public health system.
