Cinética de bioacumulación de hidrocarburos aromáticos policíclicos en Anadara similis (Adams, 1852) Y Anadara tuberculosa (Sowerby, 1833) (Arcoida: Arcidae)

Abstract

Se determinó la bioacumulación de hidrocarburos aromáticos policíclicos (HAP) en las los moluscos bivalvos Anadara similis y A. tuberculosa, siendo esta última especie empleada como organismo biomonitor, en el Pacífico colombiano. Un total de 120 organismos de cada especie fueron expuestos a una mezcla de los 16 HAP considerados contaminantes prioritarios, por la Environmental Protection Agency (US EPA), suministrados a concentraciones establecidas a partir de niveles considerados seguros para la vida acuática. Los organismos fueron expuestos a una concentración de 15,48ng/mL de la mezcla de HAP, por un periodo de 45 días, para A. tuberculosa y 30, para A. similis; la prueba con esta última especie tuvo menor duración, debido a la mortalidad registrada durante el ensayo, la cual, se asocia con la duración del periodo de aclimatación, que abarcó 10 días. Los máximos niveles de acumulación registrados en A. tuberculosa (48,00 x 102 ng/g) y A. similis (75,00 x 102 ng/g), se presentaron luego de 30 y 25 días de exposición, respectivamente, evidenciándose una mayor capacidad de bioacumulación por parte de A. similis y, por ende, un alto potencial de la misma, como organismo biomonitor de las condiciones ambientales.
