title: Assessment oxidative stress biomarkers and metal bioaccumulation in macroalgae from coastal areas with mining activities in Chile.
abstract: The aim of this study was to evaluate the effect on seaweeds Scytosiphon lomentaria and Ulva rigida of coastal waters of sites with mining activity, using oxidative stress biomarkers and heavy metal determination both in water and in tissue. The greatest bioaccumulation factors in S. lomentaria and U. rigida were founded for iron and arsenic in Quintay. Bioaccumulation factor in S. lomentaria in descending order was Fe> Cu> Zn> Cd> Cr> As> Mo and in U. rigida, in descending order, was Fe> Cu> Cd> Zn> Cr> Mo> As. Both species had higher antioxidant activity levels in areas with high mining activities. The concentration of metals in waters such as copper and arsenic in S. lomentaria, and iron, arsenic, and cadmium in U. rigida were related with oxidative stress biomarkers measured in both species. The use of both species is proposed to monitor the bioavailability and oxidative damage in coastal areas with mining activity. This work will generate a significant knowledge about the impact of mining wastes on macroalgal community in the area of north-central Chile.
