Methylmercury and total mercury distribution in tissues of gray whales (Eschrichtius robustus) and spinner dolphins (Stenella longirostris) stranded along the lower Gulf of California, Mexico

Fuente: Redalyc · Ciencias Marinas

Four gray whales Eschrichtius robustus and eleven spinner dolphins Stenella longirostris were found stranded along the coasts of the lower Gulf of California, Mexico. Muscle, kidney and liver samples from all the specimens were used for mercury (Hg) analysis. Mean concentrations of total Hg (THg) we...

Se encontraron varadas cuatro ballenas grises Eschrichtius robustus y once delfines tornillo Stenella longirostris a lo largo de las costas del bajo Golfo de California, México. Se utilizaron muestras de músculo, riñón e hígado de todos los especímenes para los análisis de mercurio (Hg). Las concentraciones medias de Hg total fueron significativamente diferentes (P < 0.05) en todos los tejidos de los delfines tornillo, resultando en un orden decreciente de concentraciones hígado>riñón>músculo. Los valores medios de Hg total en los tres tejidos de las ballenas grises no fueron estadísticamente diferentes. De manera similar, los niveles de metilmercurio (MeHg) en los tejidos analizados de los delfines y de las ballenas no fueron estadísticamente diferentes. Considerando que existen diferencias a nivel de especies, al parecer los niveles de Hg total y de MeHg en los mamíferos marinos estudiados no jugaron un papel decisivo en el varamiento de los organismos, aunque se requieren más estudios acerca de las implicaciones de los compuestos de Hg durante los eventos de varamiento.
