“…Over the past few decades, many pieces of research on migration of lead from ceramic materials have emerged owing to its high toxicity, and a number of empirical, thermodynamic and kinetic mathematical models were reported to describe the migration behaviour of lead . However, only a few investigations have been conducted on migration of cadmium from ceramic materials, and the mechanism and kinetic mathematical models of the cadmium leaching are rare. Therefore, the first purpose of this study was to investigate the leaching mechanisms and kinetics of lead and cadmium from ceramic food contact materials into acid food simulants under various time–temperature conditions.…”

Migration studies of lead and cadmium from ceramic food contact materials into acid food simulants were conducted under various time-temperature conditions to investigate the kinetics of the leaching of lead and cadmium. A mathematical model based on one-dimensional Fickian diffusion theory was derived in order to describe the migration behaviour of lead and cadmium. Moreover, diffusion coefficients of toxic metals were obtained by fitting the short-time (24 h) migration data to the model. Comparisons of model solutions with experimental data obtained from the medium-time tests (up to 600 h) and long-time tests (up to 130 days) were carried out to verify the proposed model and the values of diffusion coefficients obtained from the short-time test. Results show that the model fits the experimental data obtained under 20 and 40°C well but fails to fit the experimental data at 60°C. This indicates a change of the migration mechanisms from ion exchange to glass network dissolution as a result of higher temperature. Furthermore, results of migration experiments also reveal that the effects of temperature on the diffusion of lead and cadmium follow the Arrhenius law and that the leaching amounts of lead and cadmium decrease with pH value of the food simulant.

“…The amount of metal migration depends on several factors, including the type of metal used in the utensil, the quality of the utensil, the temperature and duration of exposure to the food or beverage, and the acidity or alkalinity of the food or beverage. For example, acidic foods or beverages can cause more metal migration than neutral or alkaline ones [9,[11][12][13][14][15] .…”

Electroplating is a widely used technique in the manufacturing of utensils for household and commercial use. This process involves the deposition of a metal coating onto a base material, such as steel or brass, to improve the aesthetics, durability, and corrosion resistance of the utensil. Several studies have investigated the migration of heavy metals from utensils, but there is a lack of research specifically focused on the impact of electroplating on this phenomenon. Therefore, this research article aims to assess the impact of electroplating by analyzing the migration of heavy metals from such utensils. The objective of this research is to assess the impact of electroplating on the migration of heavy metals from utensils. The research also aims to evaluate the impact of coating thickness. Stainless‐steel and brass utensils (Plate, Tumbler, and Bowl) are purchased. The samples are analyzed as per standard test methods based on inductively coupled plasma mass spectrometry (ICP‐MS) techniques. Leaching stimulant is used for extraction process. Testing is performed in an ISO/IEC 17025: 2017 accredited laboratory. The experiments reveal that the electroplating process decreased the migration of lead from the utensils. These findings highlight the need for stricter regulations and standards to ensure the safety of electroplated utensils.

“…All these metals are used in pigments or glaze. The glaze on properly made and kilned plates and dishes should normally be unaffected by food and should not release metals during cooking or standing [10,16]. If ceramic articles are baked at the wrong temperature, the glazing will not have the desired sealing properties and harmful to human health elements can migrate into food and drink with a low pH [2,3,7,12,15,37].…”

Background. One of the important source of food contamination with elements harmful to human health such as lead or cadmium is migration from the articles intended to come into contact with food. Ceramic and glass articles can also be a source of zinc and copper which compounds are used during the production process of vessels. Objective. Determination of migration of lead, cadmium, zinc and copper from ceramic and glass wares available on the market in Poland and assessment of consumer exposure to these elements. Material and methods. Ceramic and glass articles which were available on the retail market and mainly produced in China were tested for release of lead, cadmium, zinc and copper. Samples for testing were prepared in accordance with European Standards: EN 1388-1 and EN 1388-2 and the migration of elements into a food simulant (4% acetic acid) was measured using flame atomic absorption spectrometry (FAAS). Validated and accredited methods according to EN ISO/ IEC 17025:2005 meeting the criteria set in the legislation were applied. Exposure assessment was performed taking into account actual reference doses introduced by the European Food Safety Authority (EFSA) and the Joint FAO/WHO Expert Committee on Food Additives (JECFA). Results. 736 samples of ceramic and glass wares were tested. Among investigated samples for migration of lead 82% of results were below limit of quantification (LOQ = 0.1 mg/L) of the analytical method used. For cadmium zinc and copper results below LOQ were found in 94%, 79% and 100% tested samples, respectively (Cd LOQ = 0.01mg/L; Zn LOQ = 0.05 mg/L; Cu LOQ = 0.03 mg/L). Only one sample release lead in amount higher than limit set in Polish Standard PN-B-13210:1997, it was rim of the glass mug and migration value was 4.81 mg/article. In case of cadmium there were two samples which exceeded permissible migration limit, it was flat ceramic dish and the rim of the glass mug, migration values were: 0.14 mg/dm 2 and 0.42 mg/article respectively. The most measurable results (above LOQ) in case of lead and cadmium were for the samples of ceramic and glass drinking vessels. Quantifiable amounts of zinc were found also in other groups of articles tested: flat and deep ceramic dishes. None of the tested articles released copper in amount higher than LOQ value. The risk assessment showed that lead and cadmium exposure for some of the samples far exceed the reference doses. For children, assuming a single use only of these vessels, these doses may be exceeded: in the case of lead, 69 times and in the case of cadmium, 8 times. Conclusions. It is the urgent need to introduce requirements into the applicable legislation for the rim area of drinking ceramic and glass vessels to reduce exposure especially by the most vulnerable groups of population such as children.
