Concentrations and emission rates of sixteen trace elements in emitted PM during heating soybean oil using three types of pans, including Teflon, granitium, and cast‐iron, were investigated. Statistically significant decreases in Mn and Co emission rates were observed when the oil was heated in the cast‐iron pan compared to Teflon and granitium pans. Among the released trace elements, Ni, Ba, Zn, and Cr had more contribution to the emission rate. The concentrations of Fe in the emitted PM₁ were found to be higher when cast‐iron pan (8.49 ± 3.35 µg/m³) was utilized compared to Teflon (8.05 ± 2.27 µg/m³) and granitium (7.45 ± 1.38 µg/m³). However, these increases were statistically insignificant. The results of our study support the hypothesis that the trace elements translocate from cooking pans into the heated oil and subsequently to the particulate phase. This translocation creates a new inhalation exposure route to trace elements in indoor environments.

一种新的暴露途径，可追踪室内颗粒物中的微量元素。

研究了使用特富龙，花岗岩和铸铁这三种类型的锅加热大豆油期间，排放的PM中16种微量元素的浓度和排放速率。与聚四氟乙烯锅和花岗岩锅相比，在铸铁锅中加热油时，锰和钴的排放速率在统计学上显着降低。在释放的微量元素中，Ni，Ba，Zn和Cr对排放速率的贡献更大。当使用铸铁锅（8.49±3.35 µg / m ³）时，发现排放的PM ₁中的Fe浓度比铁氟龙（8.05±2.27 µg / m ³）和花岗岩（7.45±1.38 µg / m ）高。³米）。但是，这些增加在统计上是微不足道的。我们的研究结果支持以下假设：微量元素从烹饪锅转移到加热的油中，然后转移到颗粒相。这种易位为室内环境中的痕量元素创造了一条新的吸入暴露途径。
