Analysis of the results of research into the mercury content in fish and seafood during import-export operations in Ukraine for 2019–2021

The article presents the results of research on determination mercury in fish muscles and seafood, conducted based State Research Institute for Laboratory Diagnostics Veterinary-Sanitary Examination by Atomic Absorption Spectrometry as systematic period from 2019 to 2021. Mercury content was determined atomic absorption spectrometry with direct sample injection. study carried out using a Milestone DMA-80 spectrophotometer (Italy). Certified standard samples (MERK) ion solution composition an accredited value 1.0 mg/cm2 were used construct calibration curves. detection limits seafood are according validation data: LOD limit is 0.1 μg/kg, LOQ 5.0 μg/kg. During studied period, 3368 products: 2587 sea fish, 161 freshwater 130 other types – 490 pieces, which four examples namely tuna family, found exceed maximum permissible level mercury, 0.12% total number samples. ranged 0.356 1.889 mg/kg, 1.8 times higher than MDR. It that average 0.006–0.315 significantly lower concentration marine fish. 0.008–0.472 mg/kg did not regulated norms.
