Las Chlorophytas han sido utilizadas en estudios de contaminación en metales pesados anteriormente. Estas algas tienen la capacidad de acumularse en grandes alfombras de talos que flotan y se adhieren en las rocas intermareales y costeras. Los metales pesados son sustancias que pueden ser tóxicas en bajas concentraciones. Existen métodos para la detección de estos metales como la Espectroscopia de Absorción Atómica (EAA). Esta metodología se puede utilizar con organismos que adsorben estos metales como, por ejemplo, las macroalgas. Se identificaron Ulva fasciata y Chaetomorpha gracilis, las cuales se acumulan en el litoral sur de Santo Domingo. Para buscar una forma natural de detección para la acumulación de este material biológico contaminante, U. fasciata y C. gracilis fueron evaluadas para ser consideradas como bioindicadores de contaminación por metales pesados. Se obtuvieron concentraciones promedio en U. fasciata para el cobre de 15.968 mg/kg, para el hierro de 102.985 mg/kg y para el cinc de 63.598 mg/kg. En C. gracilis, para el cobre de 62.207 mg/kg, para el hierro de 2426.081 mg/kg y para el cinc de 97.555 mg/kg. Se pudo evaluar que la división Chlorophyta sí puede ser bioindicador de metales pesados en el litoral sur de Santo Domingo, República Dominicana.

Heavy metals are substances that can be toxic in low concentrations. There are methods for the detection of these metals such as Atomic Absorption Spectroscopy (AAS). This methodology can be used with organisms that adsorb these metals, such as macroalgae. Ulva fasciata and Chaetomorpha gracilis were identified, which accumulate on the southern coast of Santo Domingo. To find a natural form of detection for the accumulation of this contaminating biological material, U. fasciata and C. gracilis were evaluated to be bioindicators of contamination by heavy metals. Average concentrations were obtained in U. fasciata for copper of 15.968 mg/kg, for iron of 102.985 mg/kg and for cinc of 63.598 mg/kg. In C. gracilis for copper of 62.207 mg/kg, for iron of 2,426.081 mg/kg and for zinc of 97.555 mg/kg. It was possible to evaluate that the Chlorophyta division, can be a bioindicator of heavy metals in the southern coast of Santo Domingo, Dominican Republic.
