This article deals with the determination and comparison of heavy metals and water-soluble anions and cations in indoor dust and outdoor dust fall in the petroleum refinery area in Jordan. Three sampling sites were considered in the Jordanian petroleum refinery complex for the collection of dust fall and office dust samples. These samples were analyzed for water-soluble anions (F-, Cl-, Br-, NO3-, C2O4(2-), and SO4(2-)) and cations (Li+, Na+, K+, Mg2+, and Ca2+) using auto-suppressed ion chromatography. Heavy metals (Pb, Cd, Cu, Zn, Cr, Fe, and Al) were determined using flame or graphite-furnace atomic absorption. No correlations were found between heavy metal concentrations in dust fall and office dust samples, indicating different sources. High enrichment factors for heavy metals were found in dust-fall samples, except for Fe and Cr. Zinc showed the highest and cadmium the lowest flux rates.
本文探讨了约旦炼油厂区域室内灰尘和室外降尘中重金属以及水溶性阴离子和阳离子的测定与比较。在约旦炼油厂综合设施中选取了三个采样点，用于采集降尘和办公室灰尘样本。使用自动抑制离子色谱法对这些样本中的水溶性阴离子（F⁻、Cl⁻、Br⁻、NO₃⁻、C₂O₄²⁻和SO₄²⁻）和阳离子（Li⁺、Na⁺、K⁺、Mg²⁺和Ca²⁺）进行分析。采用火焰或石墨炉原子吸收法测定重金属（Pb、Cd、Cu、Zn、Cr、Fe和Al）。降尘和办公室灰尘样本中的重金属浓度之间未发现相关性，表明其来源不同。除Fe和Cr外，降尘样本中重金属的富集因子较高。锌的通量率最高，镉的通量率最低。
