    Consumers are generally unaware of the toxicity of metals used in the production or decoration of ceramic ware, and even less so of the release of lead and cadmium that occurs through continuous use of ceramic plates in contact with food. Due to this issue, the present study was conducted on the “Quantitative determination of lead and cadmium release in ceramic utensils (flat and deep plates under one liter) commercialized in Metropolitan Lima during the period May–October 2014.” A total of 10 samples of deep plates and 10 samples of flat plates were analyzed. For lead in flat plates, the minimum concentration found was 1.02 mg/dm², the maximum 2.05 mg/dm², with an average release of 1.53 mg/dm². In deep plates, the minimum concentration was 2.55 mg/L, the maximum 9.74 mg/L, with an average lead release of 4.48 mg/L. For cadmium in flat plates, the minimum concentration was 0.10 mg/dm², the maximum 0.29 mg/dm², with an average release of 0.17 mg/dm². In deep plates, the minimum concentration was 0.12 mg/L, the maximum 0.71 mg/L, with an average release of 0.29 mg/L. Lead and cadmium levels were determined using the atomic absorption spectrophotometric method.
