Literature on petroleum and its toxicities understands both as simultaneously social and ecological. Beginning with scholarship on petroleum and its toxicity that captures that simultaneity and mutual constitution, this review defines petrotoxicity as the socioecological toxicity inherent in petroleum commodification. The term signals that petroleum's social and ecological toxicities are not merely related, but always/already interdependent and inherent in petroleum commodification. Thinking about petrotoxicity this way frames it as something similar to repressive and ideological apparatuses. Althusserian apparatuses shape subjects and spaces in violent and bureaucratic ways. Generating and resisting petrotoxic apparatuses are consistent themes of literature on petrotoxicity. Thinking with Stuart Hall's critique of Louis Althusser, this review concludes by highlighting scholarship showing the limits of this popular framing of power, ecology, and intervention vis-à-vis petroleum. Long-term fieldwork in North Dakota's Bakken region informs this article at various points.
