Lacquers and polyurethane sealants emit volatile organic compounds (toluene, xylene, formaldehyde, MEK) during application and curing, with off-gassing continuing for weeks to months. Veneered tables may use particleboard or MDF substrates with formaldehyde-based adhesives. Families consume food at these tables for extended periods (1-3 hours daily), and children place food directly on surfaces where chemical residues may accumulate. Sealant degradation increases VOC release.","synthesis":{"derived_risk_level":"extreme","synthesis_confidence":0.757,"synthesis_method":"compound_composition","context_used":"human_infant","context_source":"product_users","exposure_modifier":1.38,"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]).
