“…Effects of NPs on invertebrate organisms often yield conflicting results, when regarding different LC50 values obtained [42,95] or whether toxicity is caused by NPs or dissolved ions [59,71]. Often such conflicts may simply be attributable to differences in the properties of the NPs and test media employed because of their complex interaction and effect on the NP fate and behavior.…”

“…For the collembolan Folsomia candida, effects of ZnO NPs (<50 nm) on survival and reproduction were related to nanosize particles and not to the soluble form of Zn (ionic Zn) [71]. Conflicting results were found when testing ZnO (<100 nm) in a range of concentrations [59].…”

“…In these studies, the particles are typically found to be agglomerated/aggregated, for example, TiO 2 [53,62,65,66], ZnO [43,53,[66][67][68], Ag [23,69], SiO 2 [70], and CeO 2 [53]. Manzo et al [71] analyzed an ZnO NP-contaminated soil by the Brunauer-Emmett-Teller method and found that the particles were not aggregated. The author attributed this result to the spiking procedure, which consisted of mixing a dry powder of the NPs with dry soil.…”

Abstract-Metal-based nanoparticles (NPs) (e.g., silver, zinc oxide, titanium dioxide, iron oxide) are being widely used in the nanotechnology industry. Because of the release of particles from NP-containing products, it is likely that NPs will enter the soil compartment, especially through land application of sewage sludge derived from wastewater treatment. This review presents an overview of the literature dealing with the fate and effects of metal-based NPs in soil. In the environment, the characteristics of NPs (e.g., size, shape, surface charge) and soil (e.g., pH, ionic strength, organic matter, and clay content) will affect physical and chemical processes, resulting in NP dissolution, agglomeration, and aggregation. The behavior of NPs in soil will control their mobility and their bioavailability to soil organisms. Consequently, exposure characterization in ecotoxicological studies should obtain as much information as possible about dissolution, agglomeration, and aggregation processes. Comparing existing studies is a challenging task, because no standards exist for toxicity tests with NPs. In many cases, the reporting of associated characterization data is sparse, or missing, making it impossible to interpret and explain observed differences in results among studies. Environ. Toxicol.

“…The bioavailability and toxicity of ZnO NPs has been evaluated for collembolans [13][14][15] and earthworms [16] by comparing the outcome with microsized ZnO, ionic Zn forms, or both. For terrestrial isopods, the toxicity of ZnO NPs has been assessed using contaminated food as the route of exposure [17].…”

“…Regarding organisms, more information is available about freshwater receptors compared with organisms that live in the soil (Kahru and Dubourguier 2010). In general, this information focuses on tests of acute toxicity (Tourinho et al 2012;Li et al 2011), thus leaving a gap (with some exceptions) in the knowledge about potential long-term effects (Kool et al 2011;Manzo et al 2011).…”

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.
