Multiple chemical sensitivities: the social construction of an illness

Multiple chemical sensitivities (MCS) has emerged as an important and highly controversial issue in occupational health. Debate centers on whether the illness is "physical" or "psychological." A strong corporate-backed campaign has framed the debate and has pushed MCS advocates into a strategy of "proving the physical" nature of MCS. Proponents of both positions, however, share key assumptions that impede long-term efforts to benefit MCS sufferers, including acceptance of the physical/psychological dichotomy as a paradigm for the illness, a desire to rid the debate of "politics" to allow "objective scientific" data to be amassed, and a view of MCS as unique without links to other occupational illnesses. While a grassroots movement has benefited MCS sufferers in a number of important ways, the shared assumptions have impeded development of a more complex model for the illness that is reflective of a complex reality, reproduced mainstream expert/non-expert relationships, and failed to connect with the broader occupational health and safety movement. The author outlines an alternative theory and practice to begin addressing these issues, beginning with a recognition of MCS as a problem of developing knowledge within a context of class power.
