“…However, the link between particle properties and ROS generation is still undetermined in ecotoxicology;96, 134 even whether size is actually correlated to toxicity is at times noted as being controversial,134 and von Moss and Slaveykova96 describe the relationship between particle properties and ROS generation as “ the most controversial issue and greatest challenge to nano(eco)toxicology ”. This claim is based on the notion that a correlation between the properties and effects does not imply causation between the two.…”

The number of products on the market containing engineered nanoparticles (ENPs) has increased significantly, and concerns have been raised regarding their ecotoxicological effects. Environmental safety assessments as well as relevant and reliable ecotoxicological data are required for the safe and sustainable use of ENPs. Although the number of publications on the ecotoxicological effects and uptake of ENPs is rapidly expanding, the applicability of the reported data for hazard assessment is questionable. A major knowledge gap is whether nanoparticle effects occur when test organisms are exposed to ENPs in aquatic test systems. Filling this gap is not straightforward, because of the broad range of ENPs and the different behavior of ENPs compared to “ordinary” (dissolved) chemicals in the ecotoxicity test systems. The risk of generating false negatives, and false positives, in the currently used tests is high, and in most cases difficult to assess. This Review outlines some of the pitfalls in the aquatic toxicity testing of ENPs which may lead to misinterpretation of test results. Response types are also proposed to reveal potential nanoparticle effects in the aquatic test organisms.

“…A few studies investigated and clearly demonstrated that AgNPs are taken up in aquatic organisms such as molluscs (Ali, 2014;Buffet et al, 2013;Canesi et al, 2012;Ringwood et al, 2010), crustaceans (Andreï et al, 2016;Georgantzopoulou et al, 2013;Ulm et al, 2015) and fish (Ašmonaite et al, 2016;Griffitt et al, 2013;Jung et al, 2014;Kwok et al, 2012), and behave differently depending on their physico-chemical characteristics. In this way, size, coating and chemical composition were suggested as important contributing factors to the toxicity of AgNPs (Castranova, 2011;Vale et al, 2016). For instance, laboratory synthesised "coffee-coated" AgNPs were reported to be more toxic to Daphnia magna than commercial PVP-coated and non-coated AgNPs (Allen et al, 2010).…”

“…Despite the growing number of studies on the toxicity of AgNPs, their behaviour, their environmental fate in aquatic environments and the consequent effects on living organisms are still not fully understood (Foldbjerg et al, 2015;Vale et al, 2016). A few studies investigated and clearly demonstrated that AgNPs are taken up in aquatic organisms such as molluscs (Ali, 2014;Buffet et al, 2013;Canesi et al, 2012;Ringwood et al, 2010), crustaceans (Andreï et al, 2016;Georgantzopoulou et al, 2013;Ulm et al, 2015) and fish (Ašmonaite et al, 2016;Griffitt et al, 2013;Jung et al, 2014;Kwok et al, 2012), and behave differently depending on their physico-chemical characteristics.…”

-The unique properties of nanomaterials do enable them to contribute significantly to environmental protection; however at the same time, they also have a significant negative impact on the environment as well as on living organisms. Among the existing nanomaterials, gold nanoparticle (GNP) is quickly gaining grounds due to its wide ranging uses in the field of medicine, especially radiation therapy and targeted drug delivery. Apparently, the increased production, application and disposal of GNPs have led to an increased release of nanogold into the environment and there are very few studies that bring out the implications of such release. This study aims to review various applications of GNPs and their fate in the environment.
