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.
釉面和无釉陶器在土耳其以及地中海和中东的大部分国家中被广泛用于烹饪和储存食物。为了确定使用釉面和无釉陶器是否会对消费者的健康构成风险，进行了酸浸出测试。用 4%的乙酸和 1%的柠檬酸溶液对陶器进行浸出，并用氢化物发生原子吸收光谱法测量浸出液中的砷。无釉陶器的浸出液中砷的浓度范围为 30.9 至 800μg/L，而釉面陶器的浓度通常在检测限以下（0.5μg/L）至 30.6μg/L，但在一个釉面较差的系列中，砷浓度达到 110μg/L。因此，釉面较差和无釉陶器中的砷中毒风险足以令人担忧。这似乎是首次有研究报告指出陶器中的砷会释放到食物中。
