In these emissions metals are often in the form of sulfide or chloride which are\r\nreadily bioavailable to biota. Nickel (Ni) is a hazardous metal for biota and it is used as a\r\nraw material in metal industry world-wide. In this thesis Ni accumulation in signal crayfish\r\n(Pacifastacus leniusculus) was studied with two 14-d experiments in different Ni exposure\r\nconcentrations and at two different water temperatures (7 ja 17 \u00b0C). The aim was to\r\ncompare Ni accumulation at two different water temperatures in order to examine if the\r\naccumulation is dependent on the metabolic rate of an ectothermic invertebrate. Measured\r\nNi concentrations of signal crayfish differed from control treatment already at the exposure\r\nconcentrations 0.01 and 0.09 mg Ni l-1. At 7.7 mg Ni l-1 concentration nickel accumulation\r\nin signal crayfish was high, and the highest concentrations were measured from the gill\r\nsamples. Ni concentrations of gills, hepatopancreas, digestive tract, tail muscle or gonad\r\ndid not differ statistically significantly between two temperatures. It is characteristic for\r\ncrayfish to have great variance in metabolic rate between individuals. Thus, the high\r\nvariance in Ni accumulation between the exposed crayfish individuals prevented the\r\nobservation of the temperature effect. Based on this study Ni accumulates rapidly in signal\r\ncrayfish and therefore can bioaccumulate from trophic level to another especially in\r\nsituations where nickel concentration greatly exceeds its typical background levels.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Sami Ojala (saotsaoj) on 2017-10-18 06:45:29.617226.
