Cocoa (Theobroma cacao L.) is a species originating from the humid tropics. Over 70,000 km2 worldwide is dedicated to growing cocoa, and approximately 30% of its global production is concentrated in the equatorial regions of Central and South America, the Antilles and tropical Asia. The demand for cocoa is growing significantly but the presence of cadmium (Cd) in the species is a potential problem limiting its commercialization. The present study determined the Cd, Ni, Pb and Cr content in two cocoa-producing regions in northern Colombia. Foliage (leaf, bean and shell) and soil were analyzed. The mean Ni, Pb and Cr content in the plant tissue did not exceed the maximum permissible limits set by the United States Environmental Protection Agency (EPA). The mean Cd content in the beans was 0.51 mg kg-1 in region 1 and 0.66 mg kg-1 in region 2, which are considered risky per reports from the European Union and restrict the product's export. These results serve as a reference for future research on cocoa. ; O cacau (Theobroma cacao L) é uma espécie originária dos trópicos úmidos. Mais de 70.000 km2 em todo o mundo são dedicados à sua cultura e aproximadamente 30% de sua produção global está concentrada nas regiões equatoriais da América Central e do Sul, Antilhas e Ásia tropical. A demanda por cacau está crescendo significativamente, mais a presença de cádmio (Cd) nas espécies é um problema potencial que limita sua comercialização. O presente estudo determinou o teor de Cd, Ni, Pb e Cr em duas regiões produtoras de cacau no norte da Colômbia. A folhagem (folha, feijão e casca) e o solo foram analisados. O teor médio de Ni, Pb e Cr no tecido vegetal não excedeu os límites máximos permitidos estabelecidos pela Agência de Proteção Ambiental dos Estados Unidos (EPA). O conteúdo médio de Cd nos grãos foi de 0,51 mg kg-1 na região 1 e 0,66 mg kg-1 na região 2, que são considerados de risco por relatórios da União Europeia e restringem a exportação do produto. Esses resultados servem como referência para futuras pesquisas ... |
