Occurrence of per- and polyfluoroalkyl substances, pesticides, pharmaceuticals, and heavy metals in Greek backyard chicken eggs and estimation of the consumption risk.

Backyard chicken eggs are widely consumed worldwide, while they are also used as pollution bio-indicators for different groups of chemicals. In this study, home-produced eggs were collected from 17 chicken coops around Greece and analyzed for 46 per- and polyfluoroalkyl substances (PFAS), heavy metals, pesticide, and pharmaceutical residues. The number of PFAS detected per sample ranged from 17 to 24, while the mean concentration of ΣPFAS was 7.

Development, validation and applications of a GC/MS method for the simultaneous determination of 9 amphetamines and 12 NPS analogues in blood and urine.

Amphetamine-type stimulants (ATS), synthetic cathinones (SCs) and phenethylamines (PEAs) pose a challenge to toxicology laboratories. Their extensive use and misuse has led to an increase of intoxications and fatal incidents worldwide. So, the need for new analytical methods for their determination in biological samples is crucial for all toxicology laboratories for a better investigation of these cases.
