An assessment of common atmospheric part

This study assessed various methods for sampling atmospheric particulate matter (PM) and analyzing toxic metals to improve air quality understanding. The objective was to evaluate the efficiency and relevance of different methods including tapered element oscillating microbalance for sampling, and inductively coupled plasma mass spectroscopy (ICP-MS) and scanning electron microscopy coupled with energy dispersive spectrometry (SEM/EDS) for element analysis. Particulate matter was sampled, and elemental composition was determined using these advanced analytical techniques. Results indicated that low flow rates yielded higher amassed mass of particulate matter, with filter media efficiency ranking as teflon-coated glass fiber, ringed-teflon, and quartz filters. SEM/EDS analysis identified key elements such as silicon, iron, and magnesium while ICP-MS revealed metals including iron, aluminum, and lead, establishing its superiority in detecting toxic metals with lower standard deviations and detection limits. The study's findings consolidate the approach to effectively analyze toxic components within PM, emphasizing the reliability of ICP-MS for toxic metal analysis. These insights bridge the understanding of particulate matter's health impacts and showcase the need for rigorous monitoring techniques in environmental health assessments.
