Composite wood adhesives emit formaldehyde continuously; bedside tables are positioned directly at head level in bedrooms, where users spend 6-8 hours sleeping in close proximity to off-gassing compounds. Poor bedroom ventilation concentrates formaldehyde exposure. Metal drawer slides or handles may contain nickel or chromium finish. Enclosed drawer spaces concentrate formaldehyde.","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]).
