![عکس صفحه اول مقاله: Determination of arsenic leaching from glazed and non-glazed Turkish traditional earthenware Determination of arsenic leaching from glazed and non-glazed Turkish traditional earthenware](/preview/png/4430121.png)
Glazed and non-glazed earthenware is traditionally and widely used in Turkey and most of the Mediterranean and the Middle East countries for cooking and conservation of foodstuff. Acid-leaching tests have been carried out to determine whether the use of glazed and non-glazed earthenware may constitute a human health hazard risk to the consumers. Earthenware was leached with 4% acetic acid and 1% citric acid solutions, and arsenic in the leachates was measured using hydride generation atomic absorption spectrometry. Arsenic concentrations in the leach solution of non-glazed potteries varied from 30.9 to 800 μg L− 1, while the glazed potteries varied generally from below the limit of detection (0.5 μg L− 1) to 30.6 μg L− 1, but in one poorly glazed series it reached to 110 μg L− 1. Therefore, the risk of arsenic poisoning by poorly glazed and non-glazed potteries is high enough to be of concern. It appears that this is the first study reporting arsenic release from earthenware into food.
Research highlights
► Non-glazed and poorly glazed earthenware may cause a serious arsenic release into food, and drinking water.
► Good glazing can avoid or greatly reduce arsenic leaching into food.
► Leaching of arsenic from earthenware may cause serious health risk.
► This is a pioneering work showing arsenic risk due to earthenware.
