Monitoring of pyrrolizidine alkaloids in beehive products and derivatives on the Belgian market
and snacks were very low, with respective maxima of 7.61 ng/g and 0.36 ng/g. Seventy five percent among the pre-dosed food supplements based on beehive products were contaminated, with a maximum of 43 ...
Pesticide residues in Tunisian table grapes and associated risk for consumer’s health
samples contained multiple residues (4 to 24 residues), with an average of 11.6 residues per sample. Individual concentrations of pesticides in grapes ranged from 0.01 to 5.86 mg kg−1. For at least one ...
Development of a QuEChERS-Based UHPLC-MS/MS Method for Simultaneous Determination of Six Alternaria Toxins in Grapes
mycotoxin (37.5%), with a concentration range of 0.10–1.64 μg kg−1, followed by TeA (28.6%) and AOH (26.8%). ALT (10.7%), AME (3.6%), and ALS (5.4%) were also detected in some samples. To the best of our ...
Towards the use of ion mobility mass spectrometry derived collision cross section as a screening approach for unambiguous identification of targeted pesticides in food
Conclusions The screening approach proposed in this study is unconventional and based on large mass accuracy (20 ppm) and retention time windows (0.5 min) to capture, in a first step, a maximum of detected ...
Profiling of the beneficial and potentially harmful components of Trichodesma indicum seed and seed oil obtained by ultrasound-assisted extraction
present study. The T. indicum seeds were rich in oil (29.0%), phenolic compounds (PC s, 1881.2 mg/100 g) and pyrrolizidine alkaloids (PA s, 2,702,338 ng/g). Seven PC s were identified in T. indicum seeds by ...
Exposure of workers to pesticide residues during re-entry activities: A review

Performance of in silico models for mutagenicity prediction of food contact materials
(FCM) constituents were chosen as study substances since many of these lack experimental data, making them an interesting group for in silico screening. Accuracy, sensitivity, specificity, positive ...

Analytical strategies for the determination of pyrrolizidine alkaloids in plant based food and examination of the transfer rate during the infusion process
s concentration of samples purchased on the Belgian market varied greatly with matrix type ranging from< LOD to 187151 ng/g for dry samples, while for infusions and ice-tea beverages the highest PA ...
