“…Sampling can be performed utilizing mesh screens (from 25 to 500 µm) shacked on top of each other [83]. A continuous sampling device to collect wastewater has been developed by Dyachenko et al and by Talvite et al [84,85]. Since wastewater usually contains a high number of particles, a volume of 1 L is sufficient and it is not recommended to exceed 500 L for effluent water to avoid clogging of the sieve during the filtration [82].…”

Searching Nanoplastics: From Sampling to Sample Processing

Nanoplastics (NPs) are considered emerging pollutants, namely unregulated contaminants whose toxic effect on humans and the environment has been demonstrated or suspected. They are the result of the physical fragmentation of the plastics that over time reach smaller dimensions (<100 nm). The issues related to the characterization and quantification of NPs in the environmental matrices are mainly related to the infinitesimal size, to the fact that they are found in bulk, and to the different physico-chemical forms in which the same polymer can evolve over time by degradation. To deal with the study of a new class of pollutants it is necessary to assess the entire analytical method, carefully considering every single step (sampling, cleanup, qualitative, and quantitative analysis) starting from the validation method in the laboratory. This paper reviews the analytical method steps, focusing on the first ones, which the current literature often underestimates: laboratory tests, sampling, and sample processing; in fact, most errors and the quality of the analyses often depend on them. In addition, all newly introduced sample processing methods were examined.
