Currently there is no consensus for the definition of nanoplastics, but recently it was suggested that nanoplastics should be defined within the size range of 1 to 1000 nm [27]. A further categorization of nanomaterials includes origin; nanoscale materials can exist naturally or result from ...

Consequently, there is no relationship between NPs and nanomaterials and no reason to choose the same size definition. Furthermore, Gigault et al. [3] suggested the following definition: ‘nanoplastics are particles within a size ranging from 1 to 1000 nm resulting from the degradation of ...
[45,46], silver [47,48] or copper oxide [49,50]. However, gold (Au) and titanium dioxide (TiO2) nanoparticles approach the definition of chemically inert, which is an important characteristic for comparison of metal and metal-oxide nanoparticles to plastic micro- and nanoparticles [23,28,...
The findings above prompted the definition of new strategies and policies for assessing drugs’ environmental and human health risks37, including the potential contribution to antimicrobial resistance when selecting the compound’s Predicted No Effect Concentration. As the most common form of bacterial ...

Farmland soils are prone to contamination with micro- and nanoplastics through a variety of agricultural practices. Concerns are recurrently raised that micro- and nanoplastics act as vector for organic contaminants to deeper soil layers and endanger groundwater resources. Whether and to what extent mic...
Nanoplastics (NP) were considered as plastic particles that are <100 nm in the definition of engineered nanomaterials (Mattsson et al., 2015; GESAMP, 2016). Primary NP are produced for a wide range of applications such as biosensors (Velev and Kaler, 1999), photonics (Rogach et al., ...
Ideally, a regulatory definition should be comprehensive to include those nanomaterials that would pose risks, but on the other hand should not be overly broad so that the implementation is possible. A too broad definition is likely to lead to an information overload for regulators and to high ...
