In the industrialized nations of the global North, well-funded agencies like the CDC attend to citizens' health, monitoring and treating for toxic poisons like lead. How do the under-resourced nations of the global South meet such challenges? In Edges of Exposure, Noémi Tousignant traces the work of toxicologists in Senegal as they have sought to warn of and remediate the presence of heavy metals and other poisons in their communities. Situating recent toxic scandals within histories of science and regulation in postcolonial Africa, Tousignant shows how decolonization and structural adjustment have impacted toxicity and toxicology research. Ultimately, as Tousignant reveals, scientists' capacity to conduct research—as determined by material working conditions, levels of public investment, and their creative but not always successful efforts to make visible the harm of toxic poisons—affects their ability to keep equipment, labs, projects, and careers going.

“Noémi Tousignant's innovative historical ethnography of Senegalese toxicology moves science and technology studies in Africa beyond familiar images of postcolonial domination and simplified historical continuities by carefully attending to the fragments of past efforts and their valence for present and future relations between science, state, and citizens. Without losing view of global exploitation and violence, her scrutiny of African scientific institutions' failure to protect citizens retains profound respect for the sustained efforts and achievements of African scientists, and their striving for civic and professional virtue, public service, and professional advancement. A must-read for all interested in twenty-first-century Africa, toxic exposures, and global science.”

“An impressive contribution to the historical record and an urgent call to action, Noémi Tousignant's account of toxicological research in Senegal is both riveting and horrifying. Her analysis of the impacts of structural adjustment on scientific capacity in postcolonial Senegal considerably adds to discussions about the anthropology of science and the history of public health (and thus the state) in postcolonial Africa; gender in science; and the social dimensions of environmental health sciences.”

"Edges of Exposure has much to recommend it and belongs on the bookshelf of anyone interested in postcolonial and African science, toxic exposure and risk, global health, or contemporary Africa. At a brisk 149 pages of readable prose and relatively accessible academic language, it would also fit well on graduate or upper-level undergraduate reading lists."
