The direct and indirect effects of mining tailing on macroalgae were evaluated in vitro to determine the relationship between heavy metals toxicity and pH alterations caused by the presence of pollutants. The marine brown seaweed Sargassum cymosum (C. Hagard 1820) and its main epiphytic alga, the red seaweed Hypnea pseudomusciformis (Nauer, Cassano, Oliveira, 2015), were exposed to Mariana’s

Harmful Effects of Algae Sciencing

Algae are protoctists; belonging to the euakaryote kingdom Protoctista, which includes the higher organisms (i.e.not bacteria) not classed as animals, plants or fungi. Because algae photosynthesize, they are sometimes considered plants, although some of them are mobile. Algae
