“…(ECOTOX Database, 2014) Although there are only a few studies on the toxicity of nCu, 48-h LC 50 ranges from 47 μg/L to 419 μg/L for Ceriodaphnia dubia (Gao et al, 2009;Griffitt et al, 2008) and from 700 μg/L to 1500 μg/L for Danio rerio juveniles and adults (Griffitt et al, 2007;Griffitt et al, 2008). For nCuO, 24-h LC 50 ranges from 470 μg/L to 217 mg/L (Manusadžianas et al, 2012;Heinlaan et al, 2008;Blinova et al, 2010;Gallego et al, 2007), while 24-h EC 50 ranges from 30 μg/L to 126 mg/L across several organisms (Blinova et al, 2010;Mortimer et al, 2011;Kasemets et al, 2009;Mortimer et al, 2010;Jo et al, 2012). This information was used to construct species sensitivity distributions (SSDs) for freshwater organisms (Garner et al, 2015).…”

A B S T R A C TGiven increasing use of copper-based nanomaterials, particularly in applications with direct release, it is imperative to understand their human and ecological risks. A comprehensive and systematic approach was used to determine toxicity and fate of several Cu nanoparticles (Cu NPs). When used as pesticides in agriculture, Cu NPs effectively control pests. However, even at low (5-20 mg Cu/plant) doses, there are metabolic effects due to the accumulation of Cu and generation of reactive oxygen species (ROS). Embedded in antifouling paints, Cu NPs are released as dissolved Cu + 2 and in nano-and micron-scale particles. Once released, Cu NPs can rapidly (hours to weeks) oxidize, dissolve, and form CuS and other insoluble Cu compounds, depending on water chemistry (e.g. salinity, alkalinity, organic matter content, presence of sulfide and other complexing ions). More than 95% of Cu released into the environment will enter soil and aquatic sediments, where it may accumulate to potentially toxic levels (> 50-500 μg/L). Toxicity of Cu compounds was generally ranked by high throughput assays as: Cu + 2 > nano Cu(0) > nano Cu(OH) 2 > nano CuO > micron-scale Cu compounds. In addition to ROS generation, Cu NPs can damage DNA plasmids and affect embryo hatching enzymes. Toxic effects are observed at much lower concentrations for aquatic organisms, particularly freshwater daphnids and marine amphipods, than for terrestrial organisms. This knowledge will serve to predict environmental risks, assess impacts, and develop approaches to mitigate harm while promoting beneficial uses of Cu NPs.

“…24 The mechanisms of killing the fungi by ZnO NPs in different species is different, as it can alter the cellular function that result in deformation of fungal hyphae from one side and also it can disturb in development of conidia and conidiaphores and killing of hyphae. 25 One study claimed both nano and bulk ZnO showed comparable toxicity to yeast Saccharomyces cerevisiae (8-h EC50 121-134 mg ZnO/l and 24-h EC50 131-158 mg/l respectively), 26 whenever it was shown the bulk form of ZnO is more less effective to C. Albicans and other fungi in comparison to MgO, CaO and ZnO NPs could well inhibit the growth of fungi consisted of C. Albicans. 27,28 The synergism of antifungal and antioxidant effects of ZnO NPs that enhances antifungal effect of these NPs material is the other subject of discussion in the literature.…”

“…The statistical analyses have validated the differences between the two groups of particles tested (bulk and nanoparticles) of CuO (p < 0.05). As reported by Heinlaan [27], Neal [28] and Kasemets et al [29], nanoparticles are toxic to bacteria due to the release of bioavailable metal ions that cause cell membrane damage, and therefore, the inhibition of biogas production can occur.…”

Nanotechnology has an increasingly large impact on a wide range of biotechnological, pharmacological and pure technological applications. Its current use in bioenergy production from biomass is very limited. This paper examines the potential interrelationships between nanotechnology and bioenergy production through a comprehensive literature review and analysis of data from biomass characterisation studies. The aim of this review is to indicate how nanotechnology can be applied in biomass-tobioenergy conversion. This study shows currently nanotechnology has been applied in the production of only two types of biomass, i.e. sludge and algae. Hence, interaction of nanomaterials with active sludge and algal cells were examined. Our extensive literature review indicates that anaerobic digestion process in sludge can potentially be enhanced by using magnetite nanoparticles, which gives higher methane yields. On the other hand, nanosilver reduces growth and causes adverse effects on the morphology of green algae. This process for bioenergy generation has already been successfully applied to sludge and algae biomass. Our study confirms that the process can also be used in the production of bioenergy from the other biomasses, such as agricultural wastes and industrial residues. Outcomes of this work will be an important tool for implementing nanotechnology in bioenergy research.
