Prolonged feeding of terrestrial isopod (Porcellio scaber, Isopoda, Crustacea) on TiO 2 nanoparicles. Absence of toxic effect
Nanoparticles of titanium dioxide are one of most widely used nanomaterials in different products in everyday use and in industry, but very little is known about their effects on non- target cells and tissues. Terrestrial isopods were exposed to food dosed with nano-TiO(2) to give final nominal concentration 1000 and 2000 µg TiO(2)/g dry weight of food. The effects of ingested nano-TiO(2) on th...
متن کاملTransformations of mercury in the terrestrial isopod Porcellio scaber (Crustacea).
The biological cycle of mercury in the terrestrial isopod Porcellio scaber was investigated. Testing the possibility of in vivo Hg(2+) methylation was divided into two methodologically different parts. Firstly, concentrations of total mercury and MeHg in isopods P. scaber and their environment from a Hg-unpolluted area were measured by the use of validated methods (CV AAS, CV AFS). The data obt...
متن کاملToxicity of abamectin to the terrestrial isopod Porcellio scaber (Isopoda, Crustacea).
To determine effects of the antiparasitic veterinary drug abamectin on the isopod Porcellio scaber, animals were exposed for 21 days to Lufa 2.2 soil spiked at concentrations of 3-300 mg/kg dry soil. After exposure, abamectin residues in the isopods were analysed using a novel analytical method. Toxicity was evaluated on different levels of biological organisation: biochemical, cellular and the...
متن کاملReduction and methylation of mercury in the terrestrial isopod Porcellio scaber (Crustacea) and its environment.
Reduction and methylation of inorganic mercury in Porcellio scaber (Isopoda, Crustacea) and its environment were studied, using a purpose-built experimental setup where Hg cycling was followed using 203Hg2+ tracer in experiments without and with isopods. In experiment without isopods, daily reduction of 203Hg2+ to 203Hg0 under sterile and nonsterile conditions was measured for three weeks to as...
متن کاملReference values for feeding parameters of isopods (Porcellio scaber, Isopoda, Crustacea)
The advantage of using terrestrial isopods in toxicity studies is that a battery of parameters can be tested at different levels of biological complexity. Feeding parameters for example link organism level response to potential ecological consequences but a problem with using feeding parameters in toxicity tests with terrestrial isopods is their high variability. The aim of our study was to set...
