Biomass pyrolysis is the anoxic thermal conversion of biomass into a carbon rich, porous solid, often called biochar. This could be better waste management alternative for contaminated organic wastes than incineration, due to useful properties biochar and potential sequestration. There are, however, concerns about formation/destruction polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) dibenzo-p-dioxins furans (PCDD/Fs). Six wastes, including digested sewage sludges, wood food reject, were pyrolyzed (500-800°C) in full-scale relevant unit (1-5 kg hr-1). Removal efficiencies PCBs PCDD/Fs > 99% produced biochars. Biochar PAH-content (2.7-118 mgkg-1) was not significantly correlated feedstock or temperature. PAHs (2563-8285 mgkg-1), (22-113 µgkg-1), (1.8-50 ngTEQ kg-1) accumulated condensate, making this hazardous best handled as fuel high temperature combustion. Emission concentrations (0.22-421 µgNm-3) (≤2.7 pgTEQ Nm-3) mainly associated with particles below European Union's incineration thresholds. factors ranged from 0.0002 78 mg tonne-1 0.002-0.45 µgTEQ PCDD/Fs. PCDD/F-formation negligible during (≥500 °C) (69-90% net loss).

The present investigation aimed to enhance the identification of polycyclic aromatic hydrocarbons in water and beverages by employing large-volume injection (LVI) conjunction with membrane-assisted solvent extraction for gas chromatography-mass spectrometry analyses. High-purity solvents isotope-labeled standards were used calibrate create hydrocarbon (PAH) standards. Water samples from polluted rivers India commercially available collected preserved under controlled conditions. Microwave-assisted (MASE) was optimized adjusting temperature pH efficient extraction. extracts analyzed using (GC-MS) a system sensitive PAH detection. MASE-LVI-GC-MS efficiently determined 16 PAHs aqueous optimizing parameters like shaking speed, temperature, composition. Recovery percentages above 65 %, relative standard deviation 6 % guaranteed repeatability 18 during five consecutive extractions. It shown that great sensitivity achieved reaching detection limits within range nanograms per litre. In conclusion, combined GC-MS detects various beverage samples, achieving nanogram-per-liter sensitivity. offers uniform extraction, rapid analysis, reduced use across diverse matrices.
