Plastics are vital for society, but their usage has grown exponentially and contributes to the growth of pollution worldwide. The World Health Organization, WHO, already reported that microplastics (MPs) found everywhere, in waste fresh water, air soil. Regarding water effluents, waste-water treatment plants only minimize problem, trapping larger size particles. In contrast, smaller ones remain oxidation ponds or sewage sludges, even released aquifers environment. Classic procedures MPs detection still quite laborious, usually conducted off-line, involving several steps expensive equipment. Electrical Impedance Spectroscopy, EIS, is a technique allows analysis system’s electrical response, yielding helpful information about its domain-dependent on physical-chemical properties. Due superficial electronegativity MPs’ particles, EIS may allow attain purpose present work: provide fast reliable method detect/estimate concentration effluents. Among most common Polyethylene, PE, Polyvinyl Chloride, PVC. Using developed setup experimental data collection methodology, authors could differentiate between suspensions containing same different evaluated MPs, PVC assess variation, interval 0.03 0.5 g (w/w), with an error, estimated based obtained impedance modulus, around below 3% entire stimulus signal frequency range (from 100 Hz 40 MHz)

To date, the assessment of risks related to nanoplastics (NPLs) has been incipient. Attempts establish safety levels support decisions regarding restrictions on use or reuse materials derived from petrochemicals are critical, but complexity datasets makes it difficult communicate potential NPLs-related environmental risks. Therefore, seems essential reduce relevant data a factor/number that easier clarify whether there is risk and, above all, easily report information legislators so prohibition, reductions, and/or readjustments monitoring programs can be implemented accordingly. Accordingly, this study aimed propose an improved and tiered for NPLs following NORMAN network, which may outlined as follows: (i) conducting screenings assess level through deterministic methodologies (involving collection effective concentrations or, in their absence, no-effect lowest-effect concentrations, also known NOEC LOEC, respectively); (ii) comparing exceedance values obtained previously relation predicted non-environmental (PNECs); (iii) ranking different NPL types based prioritization indeces facilitate future decision-making. Of total six polymers available, was only possible deliver indices three (two freshwater one saltwater) due lack PNEC (PECs). The majority research topic focused PS. PS classified high-priority polymer, since its estimated index ≥65 (the base value 1). Furthermore, freshwater, PE indicated priority polymer (with exceeding 1000). It should noted other widely used (such PMMA PVC), insufficient data. therefore clear current management control measures products containing must reconsidered NPLs’ impacts.
