🔬 New study reveals soils are hidden sources of toxic air pollution

In Journal of Hazardous Materials, an international team with Gerhard Lammel (RECETOX) measured air–soil exchange in rural grassland and a Finnish boreal forest.

• 🌫️ PACs from fossil fuel and wood burning deposit to soil, then re-volatilize—turning soils into secondary sources
• 📈 In Finland, re-emission flux was 0.5–12 ng m−2 h−1; scaled up, it’s comparable to primary emissions from industry, household heating, and traffic
• 🌍 Secondary emissions in receptor countries may even exceed domestic primary emissions
• 🧮 Inventories, especially in less populated European countries, should include soil re-emissions
• 🧪 “We need more measurements…” — Gerhard Lammel (RECETOX)
• 🦗 Highlights the “grasshopper effect,” extending spread and lifetimes of hazardous substances

How to spot sesame oil fraud with science 🔬🌿

Ruibing Jin, Fuyun Kuang, Qi Meng, Lijin Wang, Huanlu Song, Xueping Feng, and Mingshan Zou report a volatile fingerprinting method in the Journal of Food Composition and Analysis (2026).

• 🧪 HS‑SPME‑GC‑MS with GC×GC‑MS-assisted identification authenticates traditional sesame oil
• 🔍 Detects maize oil dilution from 5% and sesame oil essence from 0.2%
• 📊 Fingerprint Similarity System uses a clear 0.900 cutoff (ROC AUC=1.000)
• 🧠 PCA/OPLS‑DA separate samples; pyrazines and guaiacol emerge as key markers
• ✅ Single workflow distinguishes dilution vs essence; robust, reproducible

Why it matters: higher specificity than e‑nose/IMS and actionable thresholds for brands, QC labs, and regulators. Next steps expand to other adulterants and commercial blind tests.

Gas chromatography powers precise decisions in pharma, environmental testing, and food safety 🔬🌿🍎. Here’s a quick guide to the GC essentials you need to master:

• Injector: Split/Splitless, PTV, on-column—match mode, temperature, and volume to sample for reproducible results.
• Carrier gas: He for robustness, H2 for speed (handle with care), N2 for economy—optimize flow and pressure.
• Column: Packed vs capillary; choose length, ID, and stationary phase (polar/non-polar) to tune resolution.
• Detector: FID (sensitive, broad), TCD (universal), ECD (for halogenated), MS (ID + quant).
• Data system: Convert signals to chromatograms; integrate peaks confidently.
• Reading a chromatogram: Use retention time for identity, peak area/height for quantity, and peak shape/count for purity. Calibrate and confirm with standards—GC-MS or HR-MS/MS when available.

Master these levers to deliver faster, cleaner, and defensible results ✅
