Background: Air pollution poses significant risks to human health. Advanced sorbents such as metalorganic frameworks (MOFs), covalent organic frameworks (COFs), and porous organic frameworks (POFs) offer high sampling efficiency for airborne pollutants. Integrating these materials into needle trap devices (NTDs) provides a solvent-free approach to air monitoring.
Methods: A systematic review was conducted using PubMed, Scopus, and Web of Science to identify studies employing MOFs, COFs, and POFs in NTDs for air sampling. Key analytical parameters, including sampling efficiency, desorption conditions, and validation against standard methods (e.g., NIOSH), were assessed.
Results: MOF-, COF-, and POF-based NTDs exhibited exceptional pollutant capture efficiency, with detection limits as low as 0.000016 μg/mL (MOFs), 0.0051 μg/mL (PAF-6), and 0.013 μg/mL (COFs) for PAHs, VOCs, and pesticides, respectively. Optimization via response surface methodology (RSM) enhanced sensitivity by 20–40% and reduced relative standard deviations (RSD) to < 10%, ensuring high reproducibility. These sorbents demonstrated long-term stability, retaining > 95% of analytes over 60 days of storage, and showed strong agreement (R² = 0.97–0.99) with standard methods (e.g., NIOSH 5515, 5600). Notably, MOF-based NTDs achieved a broad linear dynamic range (LDR) of 0.00073–12 μg/mL, outperforming traditional sorbents in trace-level detection.
Conclusion: MOF-, COF-, and POF-packed NTDs provide an efficient, cost-effective, and eco-friendly solution for air monitoring. Their high sampling capacity and compatibility with analytical methods highlight their potential for broader applications in occupational and environmental health. Further research should enhance sorbent selectivity and regeneration for improved air quality assessments.
