“…On the basis on L(E)C 50 values of ENP for environmentally relevant organisms, AgNP are classified as extremely toxic (L(E)C 50 < 0.1 mg L -1 ), and generally show the highest toxic effects towards aquatic organisms (Bondarenko et al, 2013;Kahru et al, 2010). AgNP can remain relatively stable as they pass through freshwater systems (lakes, rivers) due to being complexed with dissolved organic matter and may eventually reach estuarine or marine environments as a final sink.…”

With the ever growing use of nanoparticles in a broad range of industrial and consumer applications there is increasing likelihood that such nanoparticles will enter the aquatic environment and be transported through freshwater systems, eventually reaching estuarine or marine waters. Due to silver's known antimicrobial properties and widespread use of silver nanoparticles (AgNP), their environmental fate and impact is therefore of particular concern.In this context we have investigated the species-specific effects of low concentrations of 60 The moment at which embryos first encounter AgNP is also shown to be an important factor in the development of abnormalities, and future applications of the sea urchin embryo development test for nanoparticle toxicity testing should carefully address the specific phase of development of embryos when nanoparticles are first introduced.

“…In addition, the environment in which NPs are present determines their behavior, reactivity, and potential toxicity (Baalousha et al 2008;Bian et al 2011). Information regarding the impact of ZnO-NPs on human health as the result of occupational or public exposure is already available, but data concerning the potential impact of these NPs in the environment is still scarce despite the rapid increase of peer-reviewed articles (Maurer-Jones et al 2013;Kahru and Dubourguier 2010). Of note, data on the ecotoxicity of metal oxide NPs remain limited compared with those of other nanostructures, such as carbon-based, silver, and silica NPs.…”

“…Therefore, experiments performed with natural soils are important for the study of NPs toxicity because these more realistically resemble environmental conditions (Zhao et al 2012). 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.

“…Among the researches on different nanotechnologies, 31 % were on the nano TiO 2 , followed by nano Co (18 %), nano ZnO (17 %), nano Ag (13 %), single-wall carbon nanotubes (9 %), and nano CuO (9 %) (Kahru and Dubourguier 2010). Studies on the ecological toxicity of nanotechnologies have mainly concentrated on nanomaterial properties, such as particle size, specific surface area, zeta potential, and interaction between nanotechnologies and the environment (such as light intensity, pH value) Yin et al 2011;Vecitis et al 2010;Jin et al 2010;Li et al 2011b), while there has been little research on the effects of nanotechnologies on the entire ecosystem, such as on ecosystem diversity (Song et al 2011).…”

Nanoscience emerged in the late 1980s and is developed and applied in China since the middle of the 1990s. Although nanotechnologies have been less developed in agronomy than other disciplines, due to less investment, nanotechnologies have the potential to improve agricultural production. Here, we review more than 200 reports involving nanoscience in agriculture, livestock, and aquaculture. The major points are as follows: (1) nanotechnologies used for seeds and water improved plant germination, growth, yield, and quality. (2) Nanotechnologies could increase the storage period for vegetables and fruits. (3) For livestock and poultry breeding, nanotechnologies improved animals immunity, oxidation resistance, and production and decreased antibiotic use and manure odor. For instance, the average daily gain of pig increased by 9.9-15.3 %, the ratio of feedstuff to weight decreased by 7.5-10.3 %, and the diarrhea rate decreased by 55.6-66.7 %. (4) Nanotechnologies for water disinfection in fishpond increased water quality and increased yields and survivals of fish and prawn. (5) Nanotechnologies for pesticides increased pesticide performance threefold and reduced cost by 50 %. (6) Nano urea increased the agronomic efficiency of nitrogen fertilization by 44.5 % and the grain yield by 10.2 %, versus normal urea. (7) Nanotechnologies are widely used for rapid detection and diagnosis, notably for clinical examination, food safety testing, and animal epidemic surveillance. (8) Nanotechnologies may also have adverse effects that are so far not well known.
