Plomo y cadmio están erradicando al manatí de Tabasco

La presencia de plomo y cadmio,  en niveles de 7 y hasta 64 veces superiores a los comunes, está matando a los manatíes de Macuspana, Tabasco.

Así lo sostiene Ernesto Zazueta, presidente de la Asociación de Zoológicos, Criaderos y Acuarios de México, AC (Azcarm), que en entrevista aseguró que después de un mes y luego de hacer pruebas en el agua y de realizar necropsias a los manatíes, se detectó un agente en común que es el cadmio, que en niveles altos es muy tóxico.

De acuerdo con las pruebas realizadas al agua, hechas por especialistas del Tecnológico de Boca del Río, se encontró que “el cadmio aparece en una cantidad de 13.95 mm por unidad, cuando lo “permitido” es  de 2 miligramos, es decir, siete veces más. Mientras que el plomo, cuya medida permisible es de .15 miligramos por unidad, aparece en una cantidad de 9.54 miligramos por litro,  64 veces más de lo aceptable”, expresó.

Dijo que “en los resultados de las  necropsias se descubrieron edemas  cerebrales en los organismos,  salen con los órganos hemorrágicos, que es un efecto de haber estado en contacto con un agente tóxico”.
