This work presents the results of the evaluation of the toxicity of the water and sediments of the Calera River using the nematode Caenorhabditis elegans as a bioindicator for environmental monitoring. The quantification of heavy metals by atomic absorption spectroscopy in samples collected along the Calera River, both in water and in sediments, revealed that the concentration in water was below the permissible limits established by the Ecuadorian Environmental Standard, while in the sediment sample, the concentration values of heavy metals considerably exceeded the permissible limits, particularl...
