Some US tolerances are 10-100x higher than EU MRLs. EU applies the 'precautionary principle' setting lower limits; US applies 'risk-based assessment' accepting higher residues where toxicological data supports safety margin. Glyphosate tolerance on oats: US 30 ppm vs EU 20 ppm; chlorpyrifos on apples: US had 0.01 ppm while EU banned all uses.","synthesis":{"derived_risk_level":"moderate","synthesis_confidence":0.711,"synthesis_method":"compound_composition","context_used":"human_child","context_source":"product_users","exposure_modifier":0.977,"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]).
