“…These results suggest an impairment of the conjugation activity with the xenobiotic as a consequence of a major susceptibility caused by high temperature. Similar GSTs trend was also described by Andrade et al [9], showing an inhibition of GSTs activity when the mussels were contaminated with CNTs at increase temperature.…”

Ruditapes decussatus is a native clam from the Southern Europe and Mediterranean area, relevant to the development of sustainable aquaculture in these regions. As sessile organisms, bivalves are likely to be exposed to chemical contaminations and environmental changes in the aquatic compartment and are widely used as bioindicator species. Carbon-based nanomaterials (CNTs) use is increasing and, consequently, concentrations of these contaminants in aquatic systems will rise. Therefore, it is imperative to assess the potential toxic effects of such compounds and the interactions with environmental factors such as water temperature. For this, we exposed R. decussatus clams to four different water temperatures (10, 15, 20 and 25 °C) in the presence or absence of CNTs for 96 h. Different parameters related with oxidative stress status, aerobic metabolism, energy reserves and neurotoxicity were evaluated. The relationship and differences among water temperatures and contamination were highlighted by principal coordinates analysis (PCO). CNTs exposure increased oxidative damage as protein carbonylation (PC) in exposed clams at 10 °C. Higher temperatures (25 °C) were responsible for the highest redox status (ratio between reduced and oxidized glutathione, GSH/GSSG) observed as well as neurotoxic effects (acetylcholinesterase—AChE activity). Antioxidant defenses were also modulated by the combination of CNTs exposure with water temperatures, with decrease of glutathione peroxidase (GR) activity at 15 °C and of glutathione S-transferases (GSTs) activity at 20 °C, when compared with unexposed clams. Clams energy reserves were not altered, probably due to the short exposure period. Overall, the combined effects of CNTs exposure and increasing water temperatures can impair R. decussatus cellular homeostasis inducing oxidative stress and damage.

“…Several studies highlighted that an increase of water temperature is able to affect the bioaccumulation of pollutants, including metals, but also to modify organism' susceptibility to contaminants (Guinot et al, 2012;Banni et al, 2014;Nardi et al, 2017). However, the effect of increasing temperature on NPs is still barely investigated (Andrade et al, 2019a), and less is known on the influence of temperature rise on the combined effects between NPs and metals (Freitas et al, 2018).…”

“…Conventional herbicides also have serious consequences over beneficial insects such as earthworms exposed to conventional atrazine displayed vacuolization, pyknotic cells, and dismantled epithelial tissues, and chloragogenous layer ( Oluah et al, 2010 ). On the other hand, nano-herbicides resulted in lower toxicity to Pseudokirchneriella subcapitata and Prochilodus lineatus ( Andrade et al, 2019 ).…”

Nanomaterials (NMs) are the leading edge as an amazing class of materials that consists of at least one dimension in the range of 1–100 nm. NMs can be made with exceptional magnetic, electrical, and catalytic properties different from their bulk counterparts. We summarized unique features of NMs, their synthesis, and advances in agri-nanotechnology and cutting-edge nanobionics. The review describes advances in NMs including their applications, dosimetry to ensure biosafety, remote sensing of agro-forestry fields, nanofertilizers, and nanopesticides, and avoid post-harvest losses, gene delivery, and nanobionics. Tree nanobionics has enabled the synthesis and delivery of nanosensors, which enhance the rate of photosynthesis, detection of pathogens, and poisonous residues to ensure biosafety and biomass accumulation. Finally, we conclude by discussing challenges, future perspectives, and agro-ecological risks of using NMs.
