This assessment uses a weighted scoring model. Each category is weighted based on its relative contribution to measurable body burden, as documented in EPA biomonitoring research, the CDC National Biomonitoring Program, and peer-reviewed environmental health literature. Scores are estimates based on self-reported habits and are intended as a starting point for discussion, not a clinical measurement. View methodology and sources →
