This work reports the level and ecotoxicity impact of metals in sediments Mallorquín swamp, a protected coastal lagoon Caribbean coast Colombia. The distribution was following decreasing order: Zn > Cu Pb Cd Hg, showing statistically significant differences among sites. average concentrations were about 17 5 times higher, respectively, compared to those background values. Several contamination ...

The accumulation of cyanobacteria produced due to eutrophication processes and the increment different pollutants in water as a result industrial affects aquatic environments such ocean, rivers, swamps. In this work, cyanobacterial biomass was used biosorbent for removal commercial dye, methylene blue (MB). Thus, MB removed from obtained samples collected swamp located Colombian Caribbean. Spec...

The mouthpart deformities of chironomid larvae are considered as indicators of environmental stress caused by water pollution such as heavy metals, pesticides, but as well by organic contamination. In the present study larvae from the side channels of the Ciénaga Grande de Santa Marta were investigated. The chironomid community of the channels are dominated by species of the genera Goeldichiron...
