Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography- tandem mass spectrometry
limits of detection and quantification are in the range of 0.1-0.3 ng g−1 and 0.2-0.7 ng g−1, respectively. The applicability of the method was demonstrated on 71 human placenta samples from a Belgian ...
Monitoring of pyrrolizidine alkaloids in beehive products and derivatives on the Belgian market
detection were developed with a focus on very low LOQ s and validated for the analysis of 16 PA s and 14 PANO s in honey, honey based candies and snacks as well as beehive products based food supplements. ...
Development of a QuEChERS-Based UHPLC-MS/MS Method for Simultaneous Determination of Six Alternaria Toxins in Grapes
detection in the range of 0.03–0.21 μg kg−1, and limit of quantification in the range of 0.09–0.48 μg kg−1), and precision (relative standard deviation (RSD) ≤ 12.9%), the analytical method was successfully ...
Profiling of the beneficial and potentially harmful components of Trichodesma indicum seed and seed oil obtained by ultrasound-assisted extraction
102.7, 236.0 and 0.6 mg/100 g oil, respectively. Among ten detected hepatotoxic PA s in T. indicum seeds, intermedine/lycopsamine/indicine (90.9%), intermedine N-oxide (4.9%) and lycopsamine N-oxide (4.1%) ...

Arsenic speciation in food in Belgium. Part 2: Cereals and cereal products.
monomethyl arsonate (MA) were the only As species detected. Mean As was 0.150 ± 0.089 mg kg in rice and 0.012 ± 0.008 mg kg in the non-rice cereals. The inorganic arsenic fraction (As = As + As) dominated in ...
Analysis of mineral oil in food: results of a Belgian market survey
of liquid chromatography with gas chromatography (LC – GC) with flame ionisation detection (FID) was used for the quantification of MOSH and MOAH. Totally, 217 packed food samples were selected using ...
High abundance and diversity of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli in faeces and tonsils of pigs at slaughter.
Tryptone Bile X-glucuronide agar supplemented with 1mg/L cefotaxime) were detected in 72 faecal samples (75%; 95% CI: 64-83%) and 45 tonsil samples (47%; 95% CI: 35-59%), in numbers up to 5.5 and 5.6log10 ...
A more sensitive, efficient and ISO 17025 validated Magnetic Capture real time PCR method for the detection of archetypal Toxoplasma gondii strains in meat.
an insufficient sensitivity compared with the mouse bioassay. Here we present a method that is more sensitive (99% limit of detection: 65.4 tachyzoites per 100g of meat), economical and reliable (ISO ...
