Meat samples (n = 100) from semi-domesticated reindeer (Rangifer tarandus tarandus L.) were randomly collected from 10 grazing districts distributed over four Norwegian counties in 2008 and 2009. The main aim was to study concentrations and geographical variations in selected toxic elements; cadmium (Cd), lead (Pb), arsenic (As), copper (Cu), nickel (Ni) and vanadium (V) in order to assess the ...
Introduction. Intake of wild growing edible mushroom in selected regions of Europe (especially East and Central Europe) is signifi cant. Additionally, mushrooms are able to accumulation many times higher amounts of nutritional and toxic elements than plants, therefore knowledge on their concentration levels and changes in their content is important for human health. Material and methods. Eleven...
Many of the trace elements which have essential roles in animals, such as zinc (Zn), manganese (Mn) and copper (Cu), are required for the growth, development and maintenance of healthy bones (Rucker, 1988; Leach, 1988). Of the remaining trace or ultratrace elements, which by definition are normally present at low concentrations in animal tissues, some have a toxic effect on bone such as lead (P...
The aim of study was to integrate chemical analyses and toxicity bioassays in order to assess the environmental risk connected with the presence of trace elements in the sediments. This study examined the ecological significance of trace elements in bottom sediments by applying a set of complementary sediment quality assessment methods sediment quality guidelines (SQGs) (mean probable effect co...
concentrations of elements (as, co, cu, ni, mo, pb, v, cd, cr and zn) are studied in the surface sediments of bakhtegan lake, northwest of nyriz city, iran, to assess metal contamination. the average abundance order of trace elements content in bakhtegan lake sediments is cr>ni> v> zn> cu> co> as> pb> mo>cd. the comparison of trace elements concentration in bakhtegan lake sediments with toxicol...
