SUMMARY:

Introduction: The oil spill on the Brazilian coast is considered the most extensive environmental disaster in the history of Brazil. The state of Bahia was fourth in the amount of waste collected and first with the highest number of marine protection areas affected. The ecosystem effects can last for decades, in addition, the spill severely affected communities of artisanal fishermen, since economic, subsistence and cultural activities were harmed and the repercussions of the spill intensified with the Covid-19 pandemic. Exposure to oil components may be associated with acute neurological symptoms and little is known about such symptoms related to exposures in oil cleaning/removal work and work activity. Objective: To investigate acute neurological symptoms related to exposure to oil spills in artisanal fishermen residing in affected locations in the state of Bahia. Method: This is a cross-sectional epidemiological study with data from artisanal fishermen residing in marine protected areas affected by the oil spill off the coast of Bahia. Crude oil exposure was assessed using self-reported metrics on time and duration of slick removal tasks, crude oil exposures, exposure to oil components during fishing activity, specific symptoms they experienced during the spill, use of personal protective equipment, and lifestyle factors. Patterns of exposure to crude oil were assessed using a 5-point Likert scale (never, rarely, sometimes, most of the time, always), which were subsequently dichotomized. Prevalence ratios were calculated using logistic regression, and confidence intervals estimated using the delta method. Results: Analyzes included 959 participants who completed the survey. Most respondents were female (n = 536; 55.89%), mixed race (n = 493; 51.41%), with complete/incomplete elementary school (323; 33.79%), residents of RESEX Canavieiras (532; 55.50%) and considered fishing/shellfishing as their main job (912; 95.10%). The average age of the participants was 42.64 (standard deviation 10.64) and the mean monthly family income averaged R$239.00 (standard deviation R$127.00). Among the neurological symptoms, the most frequent was “severe headache or migraine” (368; 38.37%). Artisanal fishermen who helped remove oil/petroleum residues are twice as likely to have neurological symptoms when compared to those who did not help. Conclusion: This study provides evidence of a cross-sectional association between exposure to crude oil and acute neurological symptoms in a sample of artisanal fishermen off the coast of Bahia. Furthermore, it suggests that being female, repairing oil-containing fishing equipment, smelling oil while fishing/shellfishing, and helping to remove oil residues are more likely to have acute neurological symptoms.
