The Impact of the Storage Conditions and Type of Clearomizers on the Increase of heavy Metal Levels in Electronic Cigarette Liquids Retailed in Romania.

Introduction:
This article reports on a study that aimed to determine the concentration of heavy metals in electronic cigarette (EC) liquids sold in Romania. The study analyzed the levels of lead, nickel, zinc, and cobalt in five EC liquid samples under different conditions, including storage period and temperature. The researchers also investigated the influence of the type of clearomizer on metal transfer.

Key Points:

* The study found that lead, nickel, and zinc were present in all EC liquid samples before storage.
* The concentrations of heavy metals increased with the storage period and temperature.
* The transfer of heavy metals was more pronounced in the case of the EC liquids stored in clearomizer 2.
* The study also found that the levels of cobalt were below the detection limit in all samples.
* The researchers used atomic absorption spectrometry (aaS) to analyze the samples, and the method showed good performance characteristics.
* The study's accuracy was confirmed through the recovery of spiked samples, which ranged between 94-107%.
* The limits of detection (LOD) and quantification (LOq) were also determined for each metal.

Main Message:
The study highlights the importance of monitoring the levels of heavy metals in EC liquids, particularly in relation to storage conditions and the type of clearomizer used. The findings suggest that the storage period and temperature can significantly affect the transfer of heavy metals, which could have implications for user safety. The study also emphasizes the need for further research to evaluate the potential health effects of EC liquid consumption. Overall, the study underscores the importance of regulatory oversight and standardization in the EC industry to ensure the safety and quality of EC products.
