Environmental Epidemiology in Latin America: Impact of an Oil Spill in the Peruvian Amazon (2017-2018)
Over the past years, five large-scale oil spills have occurred in the northern Peruvian Amazon region of Loreto, resulting in over 7,000 barrels of oil being spilled into the rainforest, primarily near or in indigenous lands. Over 8,000 people from approximately 30 indigenous communities have been affected by the oil spills and interventions by government and industry have been slow, insufficient and short term, suggesting environmental injustice.
Crude oil spills are well documented to affect human and animal health, both directly via exposure to toxic chemicals, in particular polycyclic aromatic hydrocarbons (PAHs), and indirectly through impacts to water quality, agricultural production and overall ecosystem services.
This team studied the relationship between vulnerability and risk perception of oil spills with environmental justice issues. Team members traveled to Peru for eight weeks of field work in Summer 2018 and evaluated exposures to PAHs following the oil spills in invertebrates, sediment cores and humans. The team also conducted a case-control study to examine differences in oxidative stress, spirometry and asthma, obesity, hypertension and kidney function among people who “volunteered” to clean up oil spills and those living near oil spills.
The team worked with the regional health and environmental authorities on drafting and performing basic health and environmental impact assessments on the areas impacted by the oil spills. Team members also helped design an assessment of chemical exposure in select regions of Peru (focusing on chemicals associated with crude oil spills), consisting of exposure assessment, human health impact, human adaptation and response as well as environmental impact.
