Resumen
La presente investigación buscó conocer las concentraciones de cadmio y plomo que se encontraban en agua, sedimentos y Anadara tuberculosa, dentro del área de manglar en Balao. Los puntos fueron ubicados estratégicamente, pues se evaluaron cuatro puntos, de los cuales los dos primeros, se encontraban dentro de una camaronera, el otro punto muestreado fue en el Puerto Balao y finalmente se obtuvieron muestras de Anadara tuberculosa en la desembocadura del Estero El Ají. Los resultados arrojados, mostraron que no había concentraciones de Cd y Pb por encima del límite máximo permisible, según la normativa ecuatoriana, en sedimentos, ni en Anadara tuberculosa, según normativas internacionales. Sin embargo, para el agua se encontraron concentraciones de Pb que excedieron los valores máximos, aunque para el Cd, el resultado mostró niveles bajos de concentración. En cada punto se tomaron parámetros físicos químicos in situ con la finalidad de buscar correlación entre dichos parámetros.
The present investigation sought to know the concentrations of cadmium and lead that were found in water, sediments and Anadara tuberculosa, within the mangrove area in Balao. The points were strategically located, since four points were evaluated, of which the first two were inside a shrimp farm, the other sampled point was in Puerto Balao and finally samples of Anadara tuberculosa were obtained at the mouth of Estero El Ají. The results obtained showed that there were no concentrations of Cd and Pb above the maximum permissible limit, according to Ecuadorian regulations, in sediments, nor in Anadara tuberculosa, according to international regulations. However, for water, concentrations of Pb were found that exceeded the maximum values, although for Cd, the result showed low levels of concentration. At each point, physical and chemical parameters were taken in situ in order to find a correlation between these parameters.
