"When the Deepwater Horizon oil rig blew out in 2010, the immediate threats to productive deep water and estuarial fisheries and the region's fishing and energy economies were obvious. Less immediately obvious, but equally unsettling, were risks to human health posed by potential damage to the regional food web. This paper describes grassroots and regional efforts by the Gulf Coast Health Alliance: health risks related to the Macondo Spill Fishermen's Citizen Science Network project. Using a community-based participatory research approach and a citizen science structure, the multiyear project measured exposure to petrogenic polycyclic aromatic hydrocarbons, researched the toxicity of these polycyclic aromatic hydrocarbon compounds, and communicated project findings and seafood consumption guidelines throughout the region (coastal Louisiana, Mississippi, and Alabama). Description/analysis focuses primarily on the process of building a network of working fishermen and developing group environmental health literacy competencies."

"This paper is intended to complement our extended documentation and analysis of the activities of the Gulf Coast Health Alliance: Health Risks related to the Macondo Spill project Community Outreach and Dissemination Core entitled, “Building and maintaining a citizen science network with fishermen and fishing communities after the Deepwater Horizon oil disaster using a Community-Based Participatory Research (CBPR) approach.” We discuss nuances of CBPR practice, including trust-building, clarification of stakeholder expectations, balancing timelines and agendas, cultural fluency, and the importance of regional history—political-economic context, regulatory practices, and cultural life-ways—in creating social dynamics that overarch and underpin the entire process. We examine the unique role of knowledge-making hybrid structures like the project's Fishermen's citizen science network and compare/contrast this structure with other models of participatory science or deliberation. Finally, we reiterate the importance of environmental health literacy efforts, summarize project outcomes, and offer thoughts on the future roles of collaborative efforts among communities and institutional science in environmental public health."

This article provides a description of the rationale and processes adopted by the Gulf Coast Health Alliance: Health Risks related to the Macondo Spill consortium to evaluate and communicate the risk of exposure to polycyclic aromatic hydrocarbons (PAHs) in seafood over several years following the Deepwater Horizon disaster and subsequent oil spill. We examined gaps in knowledge associated with PAH toxicity following exposure to petrogenic (oil-derived) PAHs by studying the metabolic fate of PAHs and their potential toxicity using sophisticated analytical methods. Using the data generated, we developed a risk communication strategy designed to meet the needs of the stakeholder communities including a consumption guideline calculator, a web-based tool to reconcile seafood consumption with risk of adverse health effects."
