An outdoor pot experiment was designed to study the changes of growth parameters, accumulation, and distribution of Cd in poplar (Populus nigra L.) during a prolonged exposure period (growing period of 17 months including three harvest points), allowing the consideration of time effects and prolonged adaptation to Cd stress. Simultaneously, changes to the(More)
Concentrations of cadmium (Cd), arsenic (As), mercury (Hg) and lead (Pb) were measured in muscle, liver and kidney of three cetacean species, the bottlenose (Tursiops truncatus), striped (Stenella coeruleoalba) and Risso's (Grampus griseus) dolphins from the Croatian waters of the Adriatic Sea. In all three dolphin species Cd levels decreased in tissues in(More)
The concentration and relations of Cd and Pb as environmental risk factors were studied by atomic absorption spectrophotometry in the liver, kidney and muscle of free ranging wild boar (n=94) and red deer (n=45) from hunting grounds in four counties of north-east Croatia. In all four counties, the levels of Cd found in the kidney of red deer ranged from(More)
Trace elements concentrations (As, Cd, Cu, Pb and Hg) were determined in the liver, kidney and muscle of 28 red fox (Vulpes vulpes) and 16 stone marten (Martes foina) from suburban and rural habitats from Croatia. Rural and suburban habitats affected Cd and Hg levels in the muscle, liver and kidney of red fox. Significant differences in metal concentrations(More)
Concentrations of cadmium, mercury and lead were analysed by atomic absorption spectrometry in the kidney and muscle of free-living wild boar (n = 169) from hunting grounds in seven counties of continental Croatia. Mean levels of metals (mg/kg) in muscle and kidney of boars ranged as follows: Cd: 0.005-0.016 and 0.866-4.58, Pb: 0.033-0.15 and 0.036-0.441,(More)
Lead concentrations were analysed by atomic absorption spectrometry in multifloral honeys collected in central Croatia (Zagreb County) during a three-year period from 2009 to 2011. The mean levels of elements (μg/kg) in honey samples measured were: 90.8 in 2009, 189 in 2010 and 360 in 2011. Significant differences were observed, and Pb levels determined in(More)
The concentrations of As, Cd, Cu, Hg, Pb and Zn were measured in four shellfish species (oysters, mussels, scallops, warty venus) collected along the Istria Peninsula coast during autumn 2013. Mean metal levels in shellfish ranged as follows (mg/kg): As 1.69-3.91, Cd 0.15-0.99, Hg 0.06-0.2, Pb 0.33-0.74, Cu 1.23-36.2, Zn 16.3-511. Statistical analysis(More)
Beeswax foundations are a necessary material in intensive modern beekeeping. Heavy metals can accumulate in these foundations for decades, as it is a common beekeeping practice to recycle wax. Beeswax samples were analysed using GFAAS for As, Cd, Pb, and Hg concentrations during the production of beeswax foundations using casting technology with a prolonged(More)
The differences in metal exposure (As, Cd, Cu, Pb and Hg) in the muscle, liver and kidney tissues of brown bears (Ursus arctos), grey wolfs (Canis lupus), Eurasian lynxs (Lynx lynx), Eurasian badgers (Meles meles) and pine martens (Martes martes) from Croatia were observed. The highest mean Cd levels were found in kidney and liver of Eurasian badger (3.05(More)
The concentrations of 24 elements in seven honey types (multifloral, heather, common heather, bearberry, sage, mandarin orange-blossom and honeydew) collected in southern Mediterranean regions of Croatia were determined using ICP-MS. Significant differences were found in the concentrations of Ag, As, Ba, Cu, Co, Fe, K, Mg, Mn, Mo, Na, Ni, Se, Sb, U and Th(More)
