“…This is possible because many marine macroalgae can tolerate a wide range of salinities [25]. For example, Porphyra umbilicalis grows well in salinities ranging from 7 to 52 ppt [25], while Chaetomorpha indica and Ulva ohnoi can grow in salinities ranging from 5 to 45 ppt [13]. However, saline groundwater supplies often have lower salinities than those tolerated by marine macroalgae (e.g.…”

“…, which equates to 73 tonne.ha 21 .annum 21 [42], a 100 ha culture area could remove one tonne of As per annum, providing significant removal of an environmentally sensitive element. In addition, such a culture would remove nearly 11 tonnes of V per annum as well as substantial removal of most other metals at the same time.…”

Heavy Metal Contamination of Water and Soil

Biosorption of heavy metals using dried algal biomass has been extensively described but rarely implemented. We contend this is because available algal biomass is a valuable product with a ready market. Therefore, we considered an alternative and practical approach to algal bioremediation in which algae were cultured directly in the waste water stream. We cultured three species of algae with and without nutrient addition in water that was contaminated with heavy metals from an Ash Dam associated with coal-fired power generation and tested metal uptake and bioremediation potential. All species achieved high concentrations of heavy metals (to 8% dry mass). Two key elements, V and As, reached concentrations in the biomass of 1543 mg.kg 21 DW and 137 mg.kg 21 DW. Growth rates were reduced by more than half in neat Ash Dam water than when nutrients were supplied in excess. Growth rate and bioconcentration were positively correlated for most elements, but some elements (e.g. Cd, Zn) were concentrated more when growth rates were lower, indicating the potential to tailor bioremediation depending on the pollutant. The cosmopolitan nature of the macroalgae studied, and their ability to grow and concentrate a suite of heavy metals from industrial wastes, highlights a clear benefit in the practical application of waste water bioremediation.
