“…Zn is also an essential micronutrient to promote algae growth but only has positive effects at low concentrations. High Zn concentration in algae can adversely influence the physical and biochemical processes of algae growth (Trzcińska and Pawlik-Skowrońska 2013). Also, some parts of Zn can be adsorbed on the surface of algae (6.4-20.6%) (Fig.…”

“…While Cu and Fe are essential elements for algae, Pb is considered a toxic element (Shanab et al 2012). The accumulation of Pb in algae may be because algae have evolved to have different metal resistance, which is driven by edaphic conditions (Trzcińska and Pawlik-Skowrońska 2013).

In Frongoch Mine (UK), it is unclear the distribution of metals on indigenous algae and whether these species of algae can accumulate metals. This study aimed to investigate the role of indigenous algae for metal removal from acid mine drainage and understand if metals can be adsorbed on the surface of algae or/and bioaccumulated in algae. A sequential extraction procedure was applied for algae samples collected from acid mine drainage (AMD) water to identify the forms in which metals are found in algae. Concentrations of Fe, Pb, Zn, Cu and Cd were evaluated in the algae and AMD samples were collected in June and October 2019. AMDs samples had a pH value ranging between 3.5 and 6.9 and high concentrations of Zn (351 mg/L) and Pb (4.22 mg/L) that exceeded the water quality standards (Water Framework Directive, 2015). Algae Ulothrix sp. and Oedogonium sp. were the two main species in the Frongoch AMDs. The concentrations of metals in algae ranged from 0.007 to 51 mg/g, and the bioconcentration factor of metals decreased in the following order: Fe > > Pb > > Cu > Cd > Zn. It was found that Zn, Cu and Cd were adsorbed onto the surface of and bioaccumulated in the algae, while Pb and Fe were mainly bioaccumulated in the algae. Indigenous algae can be considered as a biogeochemical barrier where metals are accumulating and can be used in bioremediation methods. Also, indigenous algae could be used as a bioindicator to assess water pollution at Frongoch Mine and other similar metal mines.

Acid mine drainage (AMD) contains high concentrations of potentially toxic metals, which contaminates receiving watercourse. In Frongoch Mine (United Kingdom), it is unclear the distribution of metals on indigenous algae and whether these species of algae can accumulate metals. This study investigated the role of indigenous algae for metals removal from AMD and examined if metals can be adsorbed on the surface or/and bioaccumulated in algae. Sequential extraction procedure was applied for algae samples collected from AMD water to identify the forms in which metals are found in algae. Concentrations of Fe, Pb, Zn, Cu, and Cd in algae were determined. AMD samples were found to have pH 3.5 to 6.9 and high concentrations of Zn (351 mg/L) and Pb (4.22 mg/L) that exceeded water quality standards. Algae Ulothrix sp. and Oedogonium sp. were the two main species in the Frongoch AMDs. Concentrations of metals in algae ranged from 0.007 to 51 mg/g and the bioconcentration factor of metals decreased in the following order: Fe>>Pb>>Cu>Cd>Zn. Zn, Cu and Cd were found to be adsorbed on algae surface and bioaccumulated in the algae while Pb and Fe mainly bioaccumulated in the algae. Indigenous algae can be considered as a biogeochemical barrier to bioaccumulate algae and as a bioremediation method. Also, indigenous algae could be used as a bioindicator for the assessment of water pollution at Frongoch Mine and other metal mines.

The red microalgae Porphyridium cruentum (S.F. Gray) Nägeli usually was used as feeds, a pigment for food and cosmetic, and antiviral activity that might be became industrial interest. Similar to another microalgae, P. cruentum has an ability to remediate heavy metals pollution, however research on it still limited. This research was conducted in order to find out the accumulation of Pb, Cd, Cr, and Cu on the P. cruentum. A laboratory experiment were developed with different concentrations. Based on this research, P. cruentum with the treatment of 1 mg/L had reduced higher Cu, Pb, Cd, and Cr concentrations rather than 3 and 5 mg/L concentrations, respectively. This was also similar to the BCF, that in day 8 in order of Cu > Cr > Cd > Pb, respectively; however, in day 15 was Cu > Pb > Cd > Cr. The length of treatment influenced BCF value. P. cruentum was good for bioremediation of heavy metal pollution, with the advantage of the short of accumulation time.
