Exposure to Oil Spill Among Fishers on the Brazilian Coast in 2019/2020

In 2019/2020, the Brazilian coast was affected by the largest oil spill disaster affecting the extent of the coastline recorded in tropical oceans. The impact on fishing areas and the prohibition of seafood sales and consumption exacerbated small-scale fishers' vulnerability. The small-scale fishers (SSFs) were the most active in protecting fishing territories, carrying out cleanup efforts without adequate personal protective equipment. Following the disaster, they suffered significant economic losses, compromising food security, including consuming potentially unsafe seafood. About 5000 tons of oil residues were collected, mainly by artisanal fishers. This study aimed to describe and identify levels of exposure to oil spills in the artisanal fishers, the population affected by the disaster on the Brazilian coast.

This epidemiological cross-sectional study used a questionnaire containing 325 questions, administered to 959 artisanal fishers living in areas affected by the spill. The graded response model of the Item Response Theory (IRT) was used to classify the artisanal fishers regarding their level of exposure.

The model identified three levels of exposure: low (17.5%), medium (19.8%), and high (7.6%) in oil removal and fishing activities.

This study demonstrated that SSFs residing in areas affected by the oil spill showed different levels of oil exposure during oil removal activities and fishing/shellfishing activities. The results highlight the need for environmental monitoring of fishing territories, prioritizing these populations in disaster preparedness training, and including social, health, and labor assistance policies during and after oil spill disasters. This study contributes to planning integrated solutions for small-scale fishing programs.
