Os nanonutrientes ou elementos ultra-traço são vitais para o funcionamento saudável das células e dos tecidos e de grande importância para as plantas e os animais que os consomem. O conhecimento dos nÃveis destes elementos nas plantas ajuda-nos a fazer escolhas sensatas no que diz respeito à qualidade e quantidade de vegetais verdes necessários para a adequação da nossa dieta. Uma vez que os nanonutrientes são necessários em quantidades muito pequenas para exercerem o seu efeito fisiológico, existe normalmente uma margem estreita entre a biodisponibilidade e a toxicidade se estas considerações não forem tidas em conta. Por conseguinte, é habitual que os nutricionistas consultem tabelas de composição alimentar estabelecidas para avaliar quaisquer variações que possam surgir de espécies vegetais relacionadas. Estas tabelas só podem ser tão fiáveis quanto a precisão com que a sua determinação é feita através da aplicação de princÃpios de quÃmica analÃtica. Como tal, este livro serve para fornecer alguma informação sobre a determinação das quantidades de dois elementos importantes que são geralmente considerados nanonutrientes, normalmente estimados em partes por bilião, em alguns vegetais verdes comuns e para fornecer dados de base para tabelas de composição de alimentos regionais e internacionais.
