Contaminación de alimentos marinos por cadmio

Abstract

The research aimed to assess cadmium levels in eight seafood species and compare them with the European Union Commission (EC) - N° 1881/2006 and its (EU) N° 488/2014 amending regulation cadmium maximum permissible limits. The study was descriptive and transversal. Samples were collected three times at the Villa Maria del Triunfo (Lima) fishing terminal from Pachacamac Island, Chorrillos - sub area 3 in Lima Coastal region. Seafood samples of 100 g each one consisted of: mackerel (Trachurus picturatus murphyi), king prawns (Penaeus vannamei), Peruvian scallops (Argopecten purpuratus), white shells (Semele sp), ribbed mussels (Aulacomya ater), clams (Gari solida), pink clams (Mesonesma donacium), Humboldt squid (Dosidicus gigas) and were analyzed by atomic absorption spectrophotometry. As a result the cadmium average levels were; fish: mackerel (Trachurus picturatus murphyi) 0,35 mg / kg fresh weight; crustaceans: king prawns (Penaeus vannamei) 0,42 mg / kg fresh weight; bivalve molluscs: white shells (Semele sp), Peruvian scallops (Argopecten purpuratus), ribbed mussels (Aulacomya ater), pink clams (Mesonesma donacium) and clams (Gari solida) 0,82 – 0,83 – 1,00 – 1,28 and 1,39 mg / kg fresh weight respectively. The data shows that cadmium levels exceeded the maximum permissible limits in all samples - fish, bivalve molluscs and cephalopods, except for crustaceans.
