A novel method was developed for the rapid detection of heavy metals in firework solutions with high sensitivity and minimal pretreatment by enriching them with ethylenediaminetetraacetic acid (EDTA) reagent and analyzing them using microwave plasma torch mass spectrometry (MPT‐MS). Quantitative results showed that the limits of detection and quantification for heavy metals (Pb, Ba, Sr, and Ag) ranged from 0.05 to 0.25 and 0.38 to 0.71 μg·L−1, respectively. The linear dynamic ranges covered at least two orders of magnitude, with correlation coefficients exceeding 0.99. Fireworks from five regions in China were also analyzed quantitatively, detecting heavy metals including Pb, Ba, Sr, and Ag, with recovery rates ranging from 87.9% to 107.5%. Good separation between the firework samples from different regions was achieved by using element ratios and principal component analysis (PCA). These results from the preliminary study showed that the EDTA‐assisted MPT‐MS combined with PCA is a powerful tool for characterizing firework samples and tracing them back to their sources, which is valuable to effectively regulate and manage banned fireworks.
