Total legacy lead in CRTs: approximately 1.2-2.4 billion lbs of lead in US households and storage. CRT recycling collapsed after 2014 when the last major US CRT glass-to-glass recycler (Closed Loop Refining) shuttered — leaving millions of tons of leaded glass with no market. Some recyclers stockpiled CRTs and abandoned warehouses full of leaded glass (Columbus, OH warehouse: 207 million lbs). Flat-panel LCD and OLED replacements eliminated CRT lead but introduced mercury in CCFL backlights (3-5 mg per lamp, 6-20 lamps per display) — LED backlights (post-2012) eliminated mercury. TCLP leach testing: CRT glass frequently exceeds 5 mg/L lead threshold — classifying it as RCRA hazardous waste. Many states enacted e-waste laws specifically because of the CRT disposal crisis.","synthesis":{"derived_risk_level":"moderate","synthesis_confidence":0.734,"synthesis_method":"compound_composition","context_used":"human_adult","context_source":"product_users","exposure_modifier":1.1,"vulnerability_escalated":false,"escalation_reason":null,"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]).

Do not place CRTs in household trash or curbside recycling. Contact your local municipality or county hazardous waste program for CRT disposal options.
