“…This has also been observed in the present study, since K. pelamis is the species with the second highest content of this heavy metal ( Table 2 ). This may be due to the opportunistic diet based on invertebrates followed by K. pelamis [ 59 , 60 ], since crustaceans and mollusks are capable of accumulating higher levels of Cd than other organisms of a higher trophic level [ 18 , 61 , 62 ]. In addition, Table 2 shows the high concentrations of Zn in the different species compared to low concentrations of Cd, and this can be explained by the antagonism between these two elements, since Cd competes for the active site of Zn [ 63 , 64 ].…”

Bioaccumulation is the process by which living organisms accumulate substances, such as pesticides, heavy metals, and other pollutants, from their environment. These substances can accumulate in the organism’s tissues over time, leading to potential health risks. Bioaccumulation can occur in both aquatic and terrestrial ecosystems, and can have a significant impact on the health of both humans and wildlife. The objective of this study is to find out if the concentrations of metals in the tuna species of the Canary Islands are suitable for human consumption and if they pose a health risk. Fifteen samples of Acanthocybium solandri, Katsuwonus pelamis, Thunnus albacares, Thunnus obesus and Thunnus thynnus present in canaries were analyzed. Ten grams of muscle were taken from each specimen and the metals Al, Cd, Cr, Cu, Fe, Li, Ni, Pb and Zn were determined by Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). The tuna species that presented more metals with a higher concentration compared to the others was T. thynnus, reaching up to 100 times more than the other studied species in Fe content with 137.8 ± 100.9 mg/Kg, which may be due to the fact that it is the largest species that reaches ages of more than fifteen years. The species Thunnus thynnus should not be suitable for commercialization according to the current legislation on the concentrations of Cd in blue fish, since 75% of the specimens studied exceeded the concentration legislated for Cd. A total of 40% of the studied specimens of this this species exceeded the legislated values for the concentration of Pb in oily fish meat, so this species must be monitored to ensure that it does not pose a risk to human health.

“…Mollusks and arthropods have developed the hepatopancreas, which acts as a warehouse for all these toxins and heavy metals, even so it is not enough and it has been observed in many studies that invertebrates such as anemones, cephalopods and crustaceans have high concentrations of metals and trace elements (Adami et al, 2002;Dallinger and Prosi, 1988;Fischer and Dietrich, 2000;Iijima et al, 1998), which in the case of cephalopods have very high Cd concentrations in muscle. (Bustamante et al, 2002;Carvalho et al, 2005;Lozano-Bilbao et al, 2020a;Storelli et al, 2006Storelli et al, , 2005. For all this, they may have higher concentrations of metals and trace elements than vertebrate species.…”

“…All organisms have evolved and developed detoxification techniques for compounds that are harmful to your body, either the accumulation of these elements in the body such as in fat or in organs such as the hepatopancreas in molluscs and arthropods or the liver in most vertebrates. There are mechanisms of excretion of harmful substances that depend on the chelating substances that organisms can create (Bustamante et al, 2008;Lozano-Bilbao et al, 2020b, 2019aRaimundo et al, 2005;Rainbow and Luoma, 2011;Saénz de Rodrigáñez et al, 2005).

SISTEMA DE EVALUACIÓN DE LOS TRABAJOS Una vez recibido el manuscrito, será considerado por los editores, quienes se reservan el derecho de rechazarlo directamente o enviarlo a los revisores. Los motivos de un rechazo directo pueden ser el incumplimiento de las normas de publicación o la incoherencia del trabajo con el objetivo principal de la revista. Si el artículo pasa esta primera evaluación, será enviado a dos revisores especializados del consejo asesor, quienes podrán sugerir un tercer o cuarto revisor. Una vez recibidos los comentarios de los revisores, los editores podrán aceptar el manuscrito sin cambios, con cambios menores, con cambios mayores o rechazarlo. Una vez que los autores hayan recibido los comentarios de los editores y revisores, tendrán un tiempo prudencial de un mes para reenviar sus correcciones a la revista.

Three toxic heavy metals (Cd, Pb, and Hg) were analyzed in the newly found invasive species in the Canary Islands, Cronius ruber. Its high growth rate and its widely varied diet are affecting the Canary marine ecosystem. The study was conducted using electrothermal vaporization atomic absorption spectrometry (GF-AAS) and cold-vapor atomic absorption spectrophotometry (CV-AAS). Significant differences were found in terms of the location and sex of the specimens, with the highest concentrations being found in areas with higher tourism activity and in the female specimens. On the other hand, the conclusion of the study is that human consumption of this species does not pose any toxic risk to public health, as the levels obtained in muscle tissue do not exceed the established limits for these metals. Therefore, its consumption and the fishing of this species can stop the proliferation of the same in the Canary coasts and thus not be harmful for the ecosystem.
