The potential risk from cultural and religious practices involving mercury in Latino and Caribbean communities raises central methodological and ethical questions for risk assessment and risk communication. Here, specific cultural practices unfamiliar to most risk professionals carry significant inherent risks in the eyes of those professionals but not necessarily in the eyes of practitioners. Practitioners' past experience and history as targets of religious suppression and anti‐immigrant sentiment create a reluctance to engage with researchers or public health officials in risk assessment or preventive risk communication efforts. The potential for the risk—in this case mercury contamination in dwellings—to extend beyond the practicing community to future occupants adds to public health concern. Understanding the risks of these practices requires both an understanding of the cultural and political context, beliefs, and behaviors of mercury users and an understanding of the fate and transport of mercury in typical use scenarios. In this study, we employed ethnographic methods (interviews and participant observation) to understand beliefs and behavior about mercury use as well as quantitative modeling and measurement to estimate and assess potential exposures. This represents a new methodology tailored to situations in which traditional activities or observances that are integral components of cultural identity pose risks in and of themselves. Our findings indicate that there are different types of mercury use stemming from different cultural and religious traditions that result in different levels of exposure. Many of the mercury uses that can result in the highest exposures to mercury vapors have previously been attributed to the religious tradition of Santeria, but appear instead to have their roots outside of the religion.

Communication about risks offers a voluntary approach to reducing exposure to pollutants. Its adequacy depends on its impact on behavior. Estimating those impacts first requires characterizing current activities and their associated risk levels, and then predicting the effectiveness of risk‐reduction strategies. Characterizing the risks from chemical consumer products requires knowledge of both the physical and the behavioral processes that influence exposures. This article presents an integrated approach that combines consumer interviews, users' beliefs and behaviors, and quantitative exposure modeling. This model was demonstrated in the context of consumer exposure to a methylene chloride‐based paint stripper, showing how it could be used to evaluate current levels of risk and predict the effectiveness of proposed voluntary risk‐reduction strategies.
