Copper, zinc, mercury and arsenic content in Micropogonias furnieri and Mugil platanus of the Montevideo coastal zone, Río de la Plata

Corrales, Diego - Acuña Plavan, Alicia - Salhi, María - Saona, Gustavo - Brugnoli, Ernesto

Resumen:

Metals (Cu, Zn, Hg) and metalloid (As) concentrations were measured in Micropogonias furnieri and Mugil platanus caught in three areas along the Montevideo coastal zone during winter 2010, spring 2010 and 2011. Compared to previous studies conducted in the zone, both species showed higher (for Cu), similar (for Zn) or lower (for Hg) concentrations. The highest Hg values were found in the M. furnieri of Montevideo bay. There was no spatial variation in Cu, Zn, and As concentrations in muscle, likely due to the high mobility of both species. However, the Cu content in the liver of M. furnieri was higher in fish from the West zone. Cu, Zn and As found in the liver of M. platanus were much higher than in that of M. furnieri. A functional relationship between muscle levels of Zn and Hg and fish length of M. furnieri indicates bioaccumulation of these metals. According to the results, M. furnieri may be used as a temporal bioindicator for Hg, but not as a spatial bioindicator. Mercury levels were below the maximum safety level based on international standard values for human consumption.


Foram estudadas as concentrações de metais (Cu, Zn,Hg) e metaloides (As) em exemplares de Micropogonias furnieri e Mugil platanus coletados em três locais ao longo da costa de Montevidéu (Uruguai) durante o inverno de 2010 e as primaveras de 2010 e 2011. Comparados com estudos prévios realizados nessas áreas, ambas asespécies apresentaram concentrações maiores (para Cu),similares (para Zn) ou menores (para Hg). Os valores mais elevados de Hg foram encontrados em M. furnieri da baía de Montevidéu. Não houve variação espacial na concentração dos elementos Cu, Zn, and As, provavelmente devido à alta mobilidade de ambas as espécies.No entanto, a concentração de Cu no fígado de M. furnieri foi maior nos peixes da área Oeste. Cu, Zn e As foram encontrados em M. platanus em valores mais elevados do que no fígado de M. furnieri. A relação funcional entre os níveis de Zn e Hg no músculo e o comprimento dos peixes em M. furnieri indica bioacumulação para estes metais. De acordo com os resultados, M. furnieri pode ser utilizado como bioindicador temporal para Hg, mas não como bioindicador espacial. Os níveis de Hg registrados estiveram abaixo do nível máximo de segurança com base nos valores do padrão internacional para o consumo humano.
