Risk assessment of replacing synthetic preservatives with natural ingredients. [PDF]
EFSA JAbstract The present work, developed within the EU‐FORA fellowship programme, assessed the risk assessment of vegetable by‐product extracts as natural alternatives to synthetic preservatives in food formulations. Extracts were obtained from onion peel (Allium cepa L.), zucchini (Cucurbita pepo L.) and kale (Brassica oleracea L. var.

Automated Analysis of Pollutants in Wastewater Using Atmospheric Pressure Gas Chromatography-Tandem Quadrupole Mass Spectrometer With Robotic Autosampler and Solid Phase Micro Extraction. [PDF]
J Sep SciABSTRACT The analysis of organic pollutants using gas chromatography coupled to mass spectrometer (GC‐MS) with electron impact (EI) ionization and liquid–liquid or solid‐phase extraction (LLE or SPE) often suffer from a limited selectivity and arduous sample preparation.

Persistent Beetroot Colored Urine in a Three-Year-Old Child: A Case Report. [PDF]
Clin Case RepClinically manifest porphyria cutanea tarda (PCT) is rare in children. Of ~1400 cases diagnosed at Porphyria Center Sweden, only five were children, all with pathogenic UROD variants and HFE homozygous. Diagnosis is often delayed; in our case, beetroot‐red urine prompted suspicion despite the absence of cutaneous symptoms.

The kinetic reaction of anaerobic microbial chloerobenzenes degradation in contaminated soil
Chemical Engineering Journal Advances, 2022 The kinetic reactions of hexachlorobenzene (HCB) and coexisting chlorobenzene congeners in real HCB-contaminated soil and effects of environmental factors on degradation rate, such as solid-liquid ratio, pH and incubation temperatures, were investigated.
