Measurement of metals, especially toxic heavy metals, in aerosols on air filters is demonstrated. Simple linear empirical calibration is discussed, and performance is shown for measurement precision and typical detection limits.
An upcoming talk at SciX 2026 Conference will describe a new multimodal platform using laser ablation inductively coupled plasma–mass spectrometry (LA-ICP-MS) elemental mapping that can detect nanoparticles and microplastics in biological tissue.
