Assessment of heavy metals pollution (Hg, Cr, Cd, Ni) in the sediments of Mallorquin lagoon – Barranquilla, Colombia. In: Malvárez, G. and Navas, F. (eds.), Global Coastal Issues of 2020. Journal of Coastal Research, Special Issue No. 95, pp. 158–162. Coconut Creek (Florida), ISSN 0749-0208.

The levels of four toxic heavy metals (Hg; Cr; Cd; Ni) present in 17 sediment samples of the Mallorquin lagoon –Barranquilla (N Colombia) were investigated in order to assessing the potential risks of accumulation. The sample preparation was performed by acid microwave digestion with “Multiwave” system, carried out using GFAAS.
