'Zero-VOC' (<5 g/L) and 'low-VOC' (<50 g/L for flat, <150 g/L for non-flat) designations per EPA. But VOC content measures only the coating itself — tinting (color addition) adds 5-50 g/L of VOCs. Dark colors can convert a zero-VOC base into a low-VOC product. Biocides (MIT/BIT isothiazolinones) in wet-state preservation cause contact dermatitis — not captured in VOC measurements.","synthesis":{"derived_risk_level":"moderate_to_high","synthesis_confidence":0.715,"synthesis_method":"compound_composition","context_used":"human_child","context_source":"product_users","exposure_modifier":0.77,"vulnerability_escalated":true,"escalation_reason":"Child exposure group","compounds_resolved":2,"compounds_total":2,"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]).
