“…Similar adverse effect on the circulatory system manifested by the presence of heart oedemas and decreased heart rate was observed in zebrafish embryos exposed to Au NPs stabilized with PVP (Hlavkova et al 2020). Upregulation of oxidative stress gene expression, as well increased levels of protein biomarkers, such as catalase, superoxide dismutase, and metallothioneins were found in adult zebrafish exposed to Au NPs for 96 h. Furthermore, decreased swimming speed and abnormalities in the swimming behaviour were observed (Botha et al 2019).…”

Many important discoveries have been made in the field of nanotechnology in the last 40 years. Since then, nanoparticles became nearly ubiquitous. With their spreading use, safety concerns have warranted extensive research of nanotoxicity. This paper offers information about the occurrence, transport, and behaviour of metallic nanoparticles in the aquatic environment. It further summarizes details about parameters that dictate the toxicity of nanoparticles and discusses the general/common mechanisms of their toxicity. This review also focuses on fish exposure to nanoparticles, including the possibility of trophic transport through the food chain. Information on some of the most frequently used metallic nanoparticles, such as silver, gold, and titanium dioxide, is further elaborated on.

“…These findings confirm that a different toxicity behavior or ions and correspondent nanoparticles can be due to the different kinetics of uptake in the zebrafish. In this framework, a recent work compared the toxic effects of ionic gold (Au (III)) and small (1.16 and 11.6 nm) gold nanoparticles coated with negatively charged polyvinylpyrrolidone (Au-NPs-PVP) or citrate (Au-NPs CIT) [60]. Au-NPs-PVP and Au-NPs-CIT were less toxic than gold (III) chloride (AuCl 3 ).…”

Plasmonic nanoparticles are increasingly employed in several fields, thanks to their unique, promising properties. In particular, these particles exhibit a surface plasmon resonance combined with outstanding absorption and scattering properties. They are also easy to synthesize and functionalize, making them ideal for nanotechnology applications. However, the physicochemical properties of these nanoparticles can make them potentially toxic, even if their bulk metallic forms are almost inert. In this review, we aim to provide a more comprehensive understanding of the potential adverse effects of plasmonic nanoparticles in zebrafish (Danio rerio) during both development and adulthood, focusing our attention on the most common materials used, i.e., gold and silver.

In this study, we exposed a commonly used duckweed species—Lemna gibba L.—to twelve environmentally relevant metals and metalloids under laboratory conditions. The phytotoxic effects were evaluated in a multi-well-plate-based experimental setup by means of the chlorophyll fluorescence imaging method. This technique allowed the simultaneous measuring of the growth and photosynthetic parameters in the same samples. The inhibition of relative growth rates (based on frond number and area) and photochemical efficiency (Fv/Fo and Y(II)) were both calculated from the obtained chlorophyll fluorescence images. In the applied test system, growth-inhibition-based phytotoxicity endpoints proved to be more sensitive than chlorophyll-fluorescence-based ones. Frond area growth inhibition was the most responsive parameter with a median EC50 of 1.75 mg L−1, while Fv/Fo, the more responsive chlorophyll-fluorescence-based endpoint, resulted in a 5.34 mg L−1 median EC50 for the tested metals. Ag (EC50 0.005–1.27 mg L−1), Hg (EC50 0.24–4.87 mg L−1) and Cu (EC50 0.37–1.86 mg L−1) were the most toxic elements among the tested ones, while As(V) (EC50 47.15–132.18 mg L−1), Cr(III) (EC50 6.22–19.92 mg L−1), Se(VI) (EC50 1.73–10.39 mg L−1) and Zn (EC50 3.88–350.56 mg L−1) were the least toxic ones. The results highlighted that multi-well-plate-based duckweed phytotoxicity assays may reduce space, time and sample volume requirements compared to the standard duckweed growth inhibition tests. These benefits, however, come with lowered test sensitivity. Our multi-well-plate-based test setup resulted in considerably higher median EC50 (3.21 mg L−1) for frond-number-based growth inhibition than the 0.683 mg L−1 median EC50 derived from corresponding data from the literature with standardized Lemna-tests. Under strong acute phytotoxicity, frond parts with impaired photochemical functionality may become undetectable by chlorophyll fluorometers. Consequently, the plant parts that are still detectable display a virtually higher average photosynthetic performance, leading to an underestimation of phytotoxicity. Nevertheless, multi-well-plate-based duckweed phytotoxicity assays, combined with chlorophyll fluorescence imaging, offer definite advantages in the rapid screening of large sample series or multiple species/clones. As chlorophyll fluorescence images provide information both on the photochemical performance of the test plants and their morphology, a joint analysis of the two endpoint groups is recommended in multi-well-plate-based duckweed phytotoxicity assays to maximize the information gained from the tests.
