Mercury is released as vapor when bulbs break — toxic at room temperature. EPA recommends specific cleanup procedures for broken CFLs including ventilation for 15+ minutes. Although LED bulbs have largely replaced CFLs, billions of mercury-containing fluorescent bulbs remain in use and require proper disposal. Most states prohibit fluorescent bulb disposal in regular trash.","synthesis":{"derived_risk_level":"moderate","synthesis_confidence":0.648,"synthesis_method":"compound_composition","context_used":"human_child","context_source":"product_users","exposure_modifier":0.654,"vulnerability_escalated":true,"escalation_reason":"Child exposure group","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]).
