Summary: This study compared the efficiency of a self-made ZIF-8/h-BN solid-phase microextraction (SPME) fiber and commercial Tenax in predicting the bioavailability of nitrated polycyclic aromatic hydrocarbons (NPAHs) in sediments.

The SPME fiber extraction of NPAHs in sediments fitted well with the pseudo first-order kinetic model.

Summary: In this work, a portable analytical system based on point discharge chemical vapor generation atomic emission spectrometry (PD-CVG-AES) coupling with gold filament enrichment was designed. The highly sensitive analysis of Hg2+ indirectly realized the detection of ascorbic acid (AA). The measurement is based on the fact that Ag+ can decrease the concentration of Hg2+ by forming Ag-Hg amalgam in the presence of the reductant SnCl2, while AA can pre-reduce Ag+ to Ag0, leading to the generation of silver nanoparticles (Ag NPs). The developed novel analytical strategy broadens the application of microplasma-based AES and offers a higher level of sensitivity compared to current AA detection techniques.
