The plastic related research has been an epicentre in recent times. The presence and spread of micro (nano) plastics (MNPs) are well-known the terrestrial aquatic environment. However, focus on fate remediation MNP soil groundwater is limited. bioaccumulation ingested MNPs remain unknown within digestive tract animals. There also a significant knowledge gap understanding ubiquitous organic environmental pollutants with biological systems. Reducing consumption, improving waste management practices, developing environmentally friendly alternatives some key steps needed to address pollution. For better handling protect environment from these invisible substances, policymakers researchers urgently need monitor map contamination groundwater.

A simple, sustainable, and sensitive monitoring approach of micro/nanoplastics (MNPs) in aqueous samples is crucial since it helps assessing the extent contamination understanding potential risks associated with their presence without causing additional stress to environment. In this study, a novel strategy for qualitative quantitative determination MNPs water by direct solid-phase microextraction (SPME) coupled gas chromatography–mass spectrometry (GC-MS) was proposed first time. Spherical poly(methyl methacrylate) (PMMA) irregularly shaped polyvinyl dichloride (PVDC) were used evaluate feasibility performance method. The results demonstrated that both PMMA PVDC efficiently extracted homemade SPME coating nitrogen-doped porous carbons (N-SPCs) exhibited sufficient thermal decomposition GC-MS injection port. Excellent extraction performances N-SPCs are attributed hydrophobic cross-linking, electrostatic forcing, hydrogen bonding, pore trapping. Methyl methacrylate identified as marker PMMA, while 1,3-dichlorobenzene 1,3,5-trichlorobenzene indicators PVDC. Under optimal conditions, method ultrahigh sensitivity, limit detection 0.0041 μg/L 0.0054 Notably, programmed temperature injector developed discriminate eliminate interferences intrinsic indicator compounds. Owing integration sampling, extraction, injection, into one step SPME, demonstrates exceptional eliminating necessity complex sample pretreatment procedures use organic solvents. Finally, successfully applied real samples.
