Mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH) from newspaper and magazine printing inks are the primary concern: when recycled fiber containing ink residues is used to manufacture food packaging (cereal boxes, pizza boxes, rice bags), MOSH and MOAH migrate through the packaging into food. A 2012 study by Biedermann & Grob (Journal of Chromatography A) found MOSH levels of 10-100 mg/kg in dry foods packaged in recycled cardboard, with MOAH levels of 0.5-10 mg/kg. MOSH accumulates in human tissues (liver, lymph nodes, spleen) and MOAH contains potential mutagens and carcinogens (3+ ring aromatics). The EU proposed MOSH limits of 0.5 mg/kg food and MOAH limits of 0.5 mg/kg food (detected/not detected approach for MOAH >3 rings), though a binding EU regulation has been delayed repeatedly. Germany's Mineral Oil Ordinance (Mineralolverordnung, 2022 draft, effective expected 2025) is the most advanced national regulation, requiring functional barriers in recycled fiber food packaging and setting migration limits. Bisphenol A (BPA) from recycled thermal receipt paper is a second contamination vector: thermal paper constitutes 2-4% of recovered paper but contributes disproportionate BPA to the recycled fiber pool. Studies measure BPA at 0.2-4.4 mg/kg in recycled cardboard, with migration to food at 0.01-0.1 mg/kg under standard conditions. EFSA's 2023 re-evaluation dramatically lowered the BPA tolerable daily intake from 4 ug/kg bw/day to 0.2 ng/kg bw/day (a 20,000-fold reduction), making even low-level BPA migration from recycled paper significant. Functional barriers (PET or aluminum liners within recycled cardboard packaging) can reduce migration by 90-99% but add cost and complexity to the recycling stream.","synthesis":{"derived_risk_level":"moderate","synthesis_confidence":0.612,"synthesis_method":"compound_composition","context_used":"human_infant","context_source":"available_priority","exposure_modifier":1.15,"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]).
