Abstract
Collaboration among community residents, environmental scientists, and local health agencies and providers in the Casa de Salud (Health House) project informs the environmental health agenda for Lawrence, Massachusetts, a largely Latino-populated city suffering from industrial decline, antiquated rental housing, and myriad environmental hazards. For example, when Casa learned from residents that localbotanicas sold mercury in capsules for ritual purposes, the project conducted a community-based, participatory research study that documented and described extensive mercury use among Spanish-speaking residents; in response, the Casa project partners generated educational outreach activities in Spanish and English. This report describes this community-based, participatory research study.
