Key chemical: 4-phenylcyclohexene (4-PCH) — the distinctive 'new carpet smell' from SBR latex backing. Modern carpet tiles increasingly use PVC or polyolefin backing (lower 4-PCH but different VOC profile). Carpet adhesive: solvent-based adhesives can emit toluene, xylene for weeks — water-based or pressure-sensitive alternatives are lower VOC. Carpet cleaning chemical residue: extraction cleaning leaves detergent, deodorizer, and antimicrobial residue that off-gasses. CRI Green Label Plus: industry certification for low-emission carpet and adhesive. FloorScore: broader flooring emission certification.","synthesis":{"derived_risk_level":"moderate_to_high","synthesis_confidence":0.82,"synthesis_method":"compound_composition","context_used":"human_adult","context_source":"product_users","exposure_modifier":1.265,"vulnerability_escalated":false,"escalation_reason":null,"compounds_resolved":2,"compounds_total":2,"synthesis_date":"2026-03-27","synthesis_version":"1.0.0"},"hazard_summary":{"sensitive_populations":"office workers (chronic exposure), chemically sensitive individuals, asthmatics","overall_risk":"low","primary_concerns":["4-PCH (new carpet smell): primary SBS complaint trigger from new carpet","Carpet adhesive VOCs: solvent-based emits toluene/xylene for weeks","Post-cleaning chemical residue off-gassing","Cumulative allergen and dust accumulation in carpet over time"],"exposure_routes":"Inhalation (4-PCH, adhesive VOCs, cleaning chemical residue)"},"exposure":{"routes":["inhalation"],"contact_types":["inhalation"],"users":["adult"],"duration":"hours","frequency":"daily","scenarios":["New carpet tile installation: 4-PCH and VOC off-gassing (first 1-4 weeks)","Carpet adhesive: solvent-based emits toluene/xylene for weeks","Post-cleaning residue: detergent, deodorizer off-gassing","Accumulated allergens and dust in carpet over time"],"notes":"CRI Green Label Plus: tests carpet, cushion, and adhesive for emissions of 13 chemicals including formaldehyde, 4-PCH, styrene, toluene.
