“…However, the highest effects on fecundity were observed for ZnCl 2 salt. One hypothesis is that animals assimilated Zn more quickly when it was added as ZnCl 2 salt than as oxides due to presumed greater bioavailability of the salt, and the adverse effects were most likely caused by increased intake rate rather than internal concentration (Lock and Janssen 2001;Van-Straalen et al 2005). The highest intake rate correlates with the metal in solution, and it is associated to direct uptake by way of the skin.…”

The present study assessed the uptake and toxicity of ZnO nanoparticles (NPs), ZnO bulk, and ZnCl 2 salt in earthworms in spiked agricultural soils. In addition, the toxicity of aqueous extracts to Daphnia magna and Chlorella vulgaris was analyzed to determine the risk of these soils to the aquatic compartment. We then investigated the distribution of Zn in soil fractions to interpret the nature of toxicity. Neither mortality nor differences in earthworm body weight were observed compared with the control. The most sensitive end point was reproduction. ZnCl 2 was notably toxic in eliminating the production of cocoons. The effects induced by ZnO-NPs and bulk ZnO on fecundity were similar and lower than those of the salt. In contrast to ZnO bulk, ZnO-NPs adversely affected fertility. The internal concentrations of Zn in earthworms in the NP group were greater than those in the salt and bulk groups, although bioconcentration factors were consistently \1. No relationship was found between toxicity and internal Zn amounts in earthworms. The results from the sequential extraction of soil showed that ZnCl 2 displayed the highest availability compared with both ZnO. Zn distribution was consistent with the greatest toxicity showed by the salt but not with Zn body concentrations. The soil extracts from both ZnO-NPs and bulk ZnO did not show effects on aquatic organisms (Daphnia and algae) after short-term exposure. However, ZnCl 2 extracts (total and 0.45-lm filtered) were toxic to Daphnia.

“…It was proved that while the reduction of worms in control soil was 48%, in the soil with sawdust or straw poultry manure the reductions were 41% and 22% respectively. It can be due to the low availability of food resources in control soil, because the organic matter content was much less than in the amended poultry manure (Van Stralen et al, 2005).…”

Keywords:Poultry manure Multi-Species Soil System Enzymatic activities This paper reports the effects produced on the organisms of the soil (plants, invertebrates and microorganisms), after the application of two types of poultry manure (sawdust and straw bed) on an agricultural land. The test was made using a terrestrial microcosm, Multi-Species Soil System (MS3) developed in INIA. There was no difference in the germination for any of the three species of plants considered in the study. The biomass was increased in the wheat (Triticum aestivum) coming from ground treated with both kinds of poultry manure. Oilseed rape (Brasica rapa) was not affected and regarding vetch (Vida sativa) only straw poultry manure showed significant difference. For length only Vicia sativa was affected showing a reduction when straw was exposed to poultry manure. When the effect on invertebrates was studied, we observed a reduction in the number of worms during the test, especially from the ground control (13.7%), higher than in the ground with sawdust poultry manure (6.7%), whereas in the ground with straw poultry manure, there was no reduction. The biomass was affected and at the end of the test it was observed that while the reduction of worms in the ground control was about 48%, the number of those that were in the ground with sawdust poultry manure or straw poultry manure decreased by 41% and 22% respectively. Finally, the effects on microorganisms showed that the enzymatic activities: dehydrogenase (DH) and phosphatase and basal respiration rate increased at the beginning of the test, and the differences were statistically significant compared with the values of the control group. During the test, all these parameters decreased (except DH activities) but they were always higher than in the ground control. This is why it is possible to deduce that the contribution of poultry manure caused an improvement in the conditions of fertilization and also for the soil.

“…This may result in a continuous increase of Ag accumulation in the isopods over time. The metal accumulation strategy in isopods is very efficient, nevertheless when storage limit is reached, it is very likely that toxicity will take place (Hopkin, 1990a;van Straalen et al, 2005).…”

“…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). Kinetic studies with isopods are considered a better indicator of bioavailability than body burden measurements, since the flux of the contaminants into the organisms is more important in determining toxicity than total body concentration (van Straalen et al, 2005). Even though there are no standard protocols or guidelines to test bioaccumulation in isopods, the species Porcellionides pruinosus has been previously used successfully to evaluate the uptake kinetics of the pesticide lindane (Sousa et al, 2000;Loureiro et al 2002).…”

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.
