Popular rhetoric about immigration often operates by constructing metaphoric representations of immigrants that concretize the social "problem" and connote particular solutions. Scholars have identified discursive connections between the rhetoric of immigration and representations of other human problems such as crime or war. This essay identifies another metaphor present in popular media coverage of immigration, particularly visual images of immigrants. The metaphor of "immigrant as pollutant" present in news media discourse on immigration can have serious consequences for societal treatment of immigrants as well as the policies designed to respond to immigration.
