“…Woodlice are acknowledged metal macro-accumulators (Udovic et al, 2009) with the midgut tubules, referred to as the hepatopancreas, serving as the main metal depository (Köhler et al, 1996). The tubules are comprised of two distinct types of epithelial cells: small pyramidal 'S'-cells containing Cu and sulphur-rich organelles, referred to as 'cuprosomes', with lysosome-like properties Moreover, these authors deployed transmission electron microscopy to examine the hepatopancreas and corroborated our findings that aggregates of intact nanoparticles are absent within the epithelia.…”

Isopods were exposed to contaminated Lufa 2.2 soil or alder leaves as food.Uptake and elimination rate constants for soil exposure did not significantly differ between Ag NPs and ionic Ag at 30 and 60 mg Ag/kg. For dietary exposure, the uptake rate constant was up to 5 times higher for Ag NPs than for AgNO3, but this was related to feeding activity and exposure concentrations, while no difference in the elimination rate constants was found. When comparing both routes, dietary exposure resulted in lower Ag uptake rate constants but elimination rate constants did not differ. A fast Ag uptake was observed from both routes and most of the Ag taken up seemed not to be eliminated. Synchrotron X-ray fluorescence showed Ag in the S-cells of the hepatopancreas, thus supporting the observations from the kinetic experiment (i.e. low elimination). In addition, our results show that isopods have an extremely high Ag accumulation capacity, suggesting the presence of an efficient Ag storage compartment.

“…For this purpose, isopods are suitable indicators of metal bioavailability (Dallinger et al, 1992;Hopkin et al, 1986;Loureiro et al, 2002;Udovic et al, 2009). They are known to accumulate high levels of metal in their hepatopancreas, which can accumulate up to 90% of total body metal burden (Hopkin and Martin, 1982).…”

“…It has been shown repeatedly that metal contents in isopod tissues reflect the bioavailability of a given metal in the respective terrestrial environment (Hopkin et al 1986(Hopkin et al , 1993Blanuš et al 2002;Udovic et al 2009). This will allow the relation of metal tissue concentrations of woodlice to those metal fractions that have entered the saprophagous food web (Paoletti and Hassall 1999).…”

“…Soil invertebrate species with a particular propensity to accumulate metallic pollutants in their tissues have repeatedly been used as biological indicators for metal contamination in soil (Hopkin et al 1986;Berger and Dallinger 1993;Udovic et al 2009). Despite some critical views on such a ''biological'' concept of environmental monitoring (Cortet et al 1999;Sandoval et al 2001), it is generally agreed that certain species of terrestrial invertebrates lend themselves ideally as soil bioindicator systems of metal accumulation (Van Straalen 1998;Beeby 2001) provided that certain conceptual and procedural precautions are taken into consideration (Dallinger 1994;Hendrickx et al 2003).…”

Mercury (Hg) is a trace element with high toxicological impact on potential receptors, including human beings. Global Hg emissions are predicted to increase significantly during the next 40 years. After emission, the metal is transported by air currents and precipitations, leading to increasing depositions even in areas far from emission sources. In the terrestrial environment, Hg is subjected to redistribution and transformation into different inorganic and metal-organic species that are taken up by vegetation and soil organisms. In the present study, the woodlouse (Porcellio scaber) was used as a biological indicator of total Hg pollution in the city of Dornbirn (province of Vorarlberg), Austria. Woodlice were collected from 30 sampling points scattered over the city area, 25 of them situated within a rectangular transect crossing the city area from west-northwest to east-southeast, starting near the Rheintal motorway and ending at the slopes of the Bregenzer Wald hills. In addition to woodlice, soil substrate samples were collected at nine of the selected sampling points. Total Hg concentrations were measured in isopod tissues and soil substrate samples by means of an Hg analyzer. Total Hg concentrations in isopod tissues were significantly correlated with Hg soil contents (P < 0.05). Moreover, a gradient of increasing Hg concentrations was observed in isopod samples along the transect across Dornbirn, with the lowest concentrations detected in woodlouse samples near the Rheintal motorway and the highest levels toward the ascending slopes of the Bregenzer Wald hills. This gradient of increasing Hg concentrations across the city matches a concomitant increase in wet precipitations along the same direction, indicating that deposition by wet precipitation may be an important source for Hg contamination in the city of Dornbirn. Overall, the degree of Hg contamination across the study area can be regarded as rather low, i.e., comparable with concentrations observed in other, unpolluted terrestrial habitats. It is concluded that bioindication by total Hg analysis in woodlice can be applied to distinguish between different levels and sources of contamination in urban areas.

“…ISO, ASTM, OECD). Moreover they have been widely used for the examination of metal accumulation and toxicity testing, due to their extraordinary capacity to accumulate high metal concentrations from the environment, predominantly in their hepatopancreas (Donker et al 1990;Drobne 1997;Farkas et al 1996;Godet et al 2011;Hames and Hopkin 1991;Hopkin 1990;Hornung et al 1998b;Paoletti and Hassall 1999;Udovic et al 2009). …”

Effects on survival and reproduction of Porcellio dilatatus exposed to different Cd species

2011

The woodlouse Porcellio dilatatus (Crustacea) is a suitable model organism as a biological indicator for the toxic effects evaluation induced by pollutants exposure in the environment. In this study, the influence of cadmium (Cd) species on survival and reproduction of isopods was investigated. Survival, growth and reproductive parameters (time to pregnancy, pregnancy duration, pregnancy and abortion occurrence, number of juveniles per female and juvenile weight) were recorded after isopods were exposed to two species of Cd deployed in food: Cd(Cys)(2) and Cd(NO(3))(2). There was a difference between survival rates of exposed males and females to both Cd species but in the case of Cd(NO(3))(2) these differences were more accentuated, with females having higher survival rates. In the presence of both metal species a reduction in the number of pregnancies and pregnancy duration was observed, while in the case of Cd(Cys)(2) all pregnancies were inconclusive. The number of juveniles delivered per female fed with Cd(NO(3))(2) contaminated food was lower than in the control, whereas the juvenile weights were higher. To the best of our knowledge, the present study is the first toxicity test demonstrating that metal speciation affects reproduction in isopods. Cd(Cys)(2) showed to be the most toxic of the contaminants tested in this long term exposure and capable of jeopardizing the reproduction efforts of isopods.
