Human health risks were evaluated from consumption of heavy metal contaminated fish the Fırtına and Güneysu Rivers in Rize. The study was aimed to assess load water two species. potential human risk due Oncorhynchus mykiss Salmo coruhensis assessed by estimating average daily intake (EDI), target hazard quotient (THQ) index (HI) metals. Our results showed that levels metals both species are lower than acceptable limit recommended Food Agricultural Organization (FAO) World Health (WHO).

The aim of the present study was to determine most significant heavy metal concentration in hen eggs, particular compare eggs originating from industrial poultry farms versus free-range hens. sampling process carried out between October and December 2018, Republic Kosovo. In total, 22 random egg samples were collected, with 54.5% 45.5% coming hens, respectively. measurements metals taken by inductively coupled plasma mass spectrometry (ICP-MS), using a wide range elements, only important...

Abstract BACKGROUND: Rize in Turkey was contaminated by the Chernobyl accident 1986. A comprehensive study planned and carried out to determine radioactivity levels heavy metal concentrations four food categories collected 2008, 2009 2010. RESULTS: Tomato showed highest concentration of 238 U, at 9.43 ± 0.128 Bq kg −1 , whereas lowest 0.20 0.02 measured aubergine samples. The 232 Th 3.22 0.29 grape 40 K found contribute activity all 137 Cs 10.20 4.19 for parsley. average contribution range...

All living creatures in nature are constantly exposed to ionising radiation, which is emitted from natural and artificial radiation sources. For this reason, it important monitor the levels of radioactivity spaces visited areas. In study, (238U, 232Th, 40K) (137Cs) concentrations sediment samples taken Borçka Black Lake located on Nature Park Artvin province were determined using a high purity germanium detector (HPGe). It was that 238U, 40K 137Cs radioisotope varied between 8.73 26.45, 7.01...

The aim of this study was to determine naturally occurring radionuclides ( 40 K, 226 Ra and 232 Th) the artificial radionuclide 137 Cs in various honey samples from Kosovo.This is particular importance because it first effort evaluate contamination by radioactivity at country level.The average concentrations Ra, Th, K on were found be 0.49±0.15,1.28±0.18,1.03±0.11and 20.44±0.69Bq kg -1 , respectively.The activity values well below limit value (1000 Bq ) recommended ICRP foodstuffs.Only 20%...

The most widely used method to determine the level of tritium in humans is testing urine.
