MDF is engineered wood made from wood fibers bonded with formaldehyde-based adhesive; melamine coating adds additional formaldehyde off-gassing. These units are placed in living rooms and bedrooms, typically in proximity to seating where occupants spend 2-4 hours daily watching television. Poor ventilation around entertainment units (enclosed in cabinets, positioned against walls) concentrates formaldehyde exposure. Metal frame components may contain nickel or chromium finish.","synthesis":{"derived_risk_level":"extreme","synthesis_confidence":0.757,"synthesis_method":"compound_composition","context_used":"human_child","context_source":"product_users","exposure_modifier":1.265,"vulnerability_escalated":false,"escalation_reason":null,"compounds_resolved":1,"compounds_total":1,"synthesis_date":"2026-05-09","synthesis_version":"1.2.0","methodology_note":"exposure_modifier and adjusted_magnitude are computed from ALETHEIA-calibrated heuristics (route × duration × frequency multipliers, clamped to [0.5, 1.4]).
