The internal surface of food and beverage cans is generally covered with polymeric coatings to preserve food and protect metal substrate from corrosion. Coating materials are complex formulations that contain different starting substances (e.g., monomers, prepolymers, additives, etc.) and in addition during the manufacture of the material several compounds can be formed (e.g., reaction products, degradation products, etc.). These substances have the potential to migrate into the food. Many of them have not been identified and only some have been toxicologically evaluated. This article aims to provide a comprehensive review on the analytical methods used for the identification of potential migrants in can coatings. The migration and exposure to chemicals migrating from can coatings are also reviewed and discussed so far, which is essential for risk assessment. Moreover, a brief section on the current status of the legislation on varnishes and coatings for food contact in Europe is also presented. Liquid chromatography coupled to diode array and fluorescence detectors and particularly to mass spectrometry and gas chromatography–tandem mass spectrometry seem to be the techniques of choice for the identification of potential migrants in can coatings. Some studies have reported migration levels of BPA (bisphenol A) and BADGE (bisphenol A diglycidyl ether) and derivatives exceeding the specific migration limits set in the European legislation. On the whole, low dietary exposure to migrants from can coatings has been reported. However, it is interesting to highlight that in these studies the combined exposure to multiple chemicals has not been considered

This research begins with the following question: How do Chilean school children in a public primary school in Santiago represent their Haitian migrant classmates? A quantitative approach was with a survey selected as the main data collection tool. The variables included gender and year level. The results show that female students and those aged between 6 and 9 tend to socially represent Haitian students in an evaluative manner while male students and those aged between 10 and 15 tend to generate prejudiced and dismissive representations of migrants., O artigo parte da seguinte pergunta: Como os escolares chilenos do ensino básico de uma escola pública de Santiago representam seus companheiros migrantes haitianos? É utilizada uma abordagem quantitativa que utiliza a pesquisa como um instrumento de estudo fundamental. As variáveis examinadas são gênero e nível escolar de acordo com a idade do corpo discente, resultando, por um lado, que estudantes do sexo feminino e entre 6 e 9 anos tendem a representar socialmente os alunos haitianos de forma avaliativa e, por outro lado, que estudantes do sexo masculino e entre 10 e 15 anos tendem a gerar representações preconceituosas e subestimadas dos migrantes., Se parte de la siguiente pregunta: ¿cómo representan las y los escolares chilenos de educación básica de una escuela pública de Santiago a sus compañeras y compañeros migrantes haitianos? Se utiliza un enfoque cuantitativo que recurre a la encuesta como instrumento fundamental de estudio. Las variables examinadas son el género y el nivel escolar según la edad del estudiantado, dando como resultado, por un lado, que las estudiantes de género femenino y quienes cursan de 1º a 4º año básico tienden a representar socialmente al estudiantado haitiano de modo positivo y, por otro lado, que los estudiantes de género masculino y quienes cursan de 5º a 8º año básico tienden a generar representaciones prejuiciosas y desestimadas de las y los migrantes.
