“…Later, these NPs are migrated from roots to other parts of the plants, and accumulation occurs [171]. Shifting of NPs from one trophic level to another trophic level takes place as the microbes, plant products or their waste materials are utilized or consumed by various organisms such as protozoa, arthropods, annelids, mollusks, fish, insects, birds and mammals [172,173]. This demonstrates that the adverse effects may be inherited by their offspring [174].…”

A large number of metallic nanoparticles have been successfully synthesized by using different plant extracts and microbes including bacteria, fungi viruses and microalgae. Some of these metallic nanoparticles showed strong antimicrobial activities against phytopathogens. Here, we summarized these green-synthesized nanoparticles from plants and microbes and their applications in the control of plant pathogens. We also discussed the potential deleterious effects of the metallic nanoparticles on plants and beneficial microbial communities associated with plants. Overall, this review calls for attention regarding the use of green-synthesized metallic nanoparticles in controlling plant diseases and clarification of the risks to plants, plant-associated microbial communities, and environments before using them in agriculture.

“…Differences in bioaccumulation were also observed in different aqueous mesocosms, with clams and biofilms bioaccumulating the most Au nanorods (65-nm length and 315-nm diameter) compared with other species (Ferry et al 2009). Higher BMFs were also calculated for Chinese muddy loaches than for river snails following exposure to 10-to 20-nm TiO 2 NPs (Kim et al 2016).…”

“…For a particular concentration or ranges of concentrations, bioaccumulation was dependent on mode of exposure, with higher bioaccumulation observed in biofilms, quillworts (Isoetes japonica), duckweeds (Spirodela polyrhiza), and Chinese muddy loaches (Misgurnus mizolepis) following exposure to sequentially lower 20-nm TiO 2 NP concentrations than after exposure to a single high concentration (Kim et al 2016). Moreover, bioaccumulation was also dependent on route of exposure.…”

“…For example, differences in the uptake and bioaccumulation of 4-, 18-, and 30-nm AuNPs were observed among 3 morphologically distinct aquatic macrophytes: the AuNPs were absorbed into the tissues of only 2 of the 3 species (Glenn and Klaine 2013). Higher BMFs were also calculated for Chinese muddy loaches than for river snails following exposure to 10-to 20-nm TiO 2 NPs (Kim et al 2016).

The experimental determination of bioaccumulation is challenging, and a number of approaches have been developed for its prediction. It is important to assess the applicability of these predictive approaches to nanomaterials (NMs), which have been shown to bioaccumulate. The octanol/water partition coefficient (K ) may not be applicable to some NMs that are not found in either the octanol or water phases but rather are found at the interface. Thus the K values obtained for certain NMs are shown not to correlate well with the experimentally determined bioaccumulation. Implementation of quantitative structure-activity relationships (QSARs) for NMs is also challenging because the bioaccumulation of NMs depends on nano-specific properties such as shape, size, and surface area. Thus there is a need to develop new QSAR models based on these new nanodescriptors; current efforts appear to focus on digital processing of NM images as well as the conversion of surface chemistry parameters into adsorption indices. Water solubility can be used as a screening tool for the exclusion of NMs with short half-lives. Adaptation of fugacity/aquivalence models, which include physicochemical properties, may give some insights into the bioaccumulation potential of NMs, especially with the addition of a biota component. The use of kinetic models, including physiologically based pharmacokinetic models, appears to be the most suitable approach for predicting bioaccumulation of NMs. Furthermore, because bioaccumulation of NMs depends on a number of biotic and abiotic factors, it is important to take these factors into account when one is modeling bioaccumulation and interpreting bioaccumulation results.

“…Previous studies suggested that TiO 2 nanoparticles production ranged from 7800 to 38,000 metric tons per year in the USA alone and will be approximately 2.5 million metric tons by 2025 [5,6]. The fate and bioaccumulation of TiO 2 based nanomaterials (nanotubes TiO 2 -NTs) and nanoparticles (TiO 2 -NPs) in a paddy microcosm over a period of 17 days showed that the Ti levels were the highest in bioilms during the exposure period [7].…”

Use of nanotechnological based formulations and nanomaterials are increasing day-byday in wide range covering a broad typology of applications, from design and development of targeted drug delivery systems, manufacturing of pesticides, domestic appliances, textiles, to bioremediation engineering. There are therefore concerns about the environmental risks or bioaccumulation-related issues that may arise particularly resulting from the application of drug-loaded nanocarriers or efect of pesticides that reach the natural ecosystems. This is a major threat in the present era and needs to be balanced against their undoubted beneits to human society. The assessment of the physical and chemical properties of nanoparticles and nanomaterials inluencing their toxic manifestation due to accumulation in human or in animal organs is still poorly investigated. This chapter reviews the possibilities of bioaccumulation of diferent nanoscale particles and materials, their potential acute and subacute toxicological proile and their identiication and characterization in diferent organs and tissues of vertebrates.
