“…The concentrations of heavy metals in algal biomass were higher than those in the water and sediments in the Nakivubo Channelized stream sediments and water in the order of Algal biomass > sediments > stream water. This observation differs from the findings made by Levkov and Krstic (2002), since heavy metal concentrations were high in the sediments (sediments > algal biomass > river water) for most of the elements. Lead concentration was exceptionally high in sediments at site DT16 in this study (Muwanga and Barifaijo, 2006).…”

“…These high heavy metal concentrations in algae are attributed to Uganda Batteries factory, Plastic manufacture by Uganda House of plastics and a petrol station (Pb and Cd) and manufacture of galvanised iron sheets by Uganda Baati (Zn). The phenomenon show low heavy metal levels in water with algal biomass (Levkov and Krstic, 2002). The study shows that the value of algal bio-concentration factor at most of the sites including US02, US04, MT07, DT16 and CT03 were greater than 1000.…”

“…This property gives algae an added advantage as heavy metal accumulator in view of phytoextraction of such elements in urban stream ecosystems (Chmielewska and Medved, 2001;Kar et al, 2008 ). Algae have been qualified as a precise biomonitoring tool for determining and quantifying of heavy metals in aquatic ecosystems (Levkov and Krstic, 2002;Shah et al, 2009).…”

ABSTRACT:Biological technologies for wastewater remediation techniques employed to remove contaminants in urban stream water are increasingly receiving attention worldwide. The purpose of this study was therefore to determine the concentrations of lead, cadmium, copper, zinc, manganese and iron in algal biomass and establish the feasibility of using algae in phytoextraction and bio-monitoring of environmental quality. Analysis of algal biomass samples in the Nakivubo urban stream ecosystem, Kampala, Uganda, showed that there was contamination by lead, cadmium, copper and zinc as indicated by enrichment factor and pollution load index values. It is suspected that industrial and vehicular emissions are the major sources of these pollutants. Calculated bio-concentration factor was > 1000 but with low concentration thresholds in each element, suggesting that algal biomass was a very good heavy metal accumulator. The bio-concentration values in algal biomass were found to be in the order of copper > zinc > lead > cadmium in the Nakivubo Channelized stream. In conclusion, algae can be a promising aquatic bio-filter plant for phytoextraction and bio-monitoring of polluted urban stream ecosystems and wastewater.

“…The concentrations of manganese, copper, zinc, arsenic, cadmium and lead were determined in the collected algal samples according to previously reported methods (Levkov and Krstic, 2002;Murphy et al, 2008;Al-Homaidan, 2008;Al-Homaidan et al, 2011). 500 mg (dry weight) of each algal dried sample were placed in acid washed digestion tubes.…”

Wastes from both industrial and domestic sources, as well as habitat destruction have a substantial impact on the coastal environments. It causes serious problems in many countries and for several seas and oceans which leads to the extinction of several plant and animal species. Many water resources are no longer suitable for drinking or for agriculture as a result of pollution. The main aim of this study was to investigate the efficiency of four brown macroalage as bioindicators for toxic heavy metals (manganese (Mn), copper (Cu), zinc (Zn), arsenite (As), cadmium (Cd), and lead (Pb)) along Al-jubail industrial city coast at Persian Gulf (Saudi Arabia). Brown macroalage samples were collected from three different sites in three time points, January, March and May, 2010. The four collected brown macroalgae were identified as Sargassum angustifolium, Sargassum boveanum, Sargassum latifolium, and Padina gymnospora. The algal samples were cleaned using sea water and distilled water, dried, and the concentrations of various toxic metals were determined. The average concentrations of Mn, Co, Ni and Cd were within the expected limits of un-contaminated areas. However, the results indicate the high level of Zn ion accumulation in all tested brown algae, showing highest concentration in S. angustifolium > P. gymnospora > S. latifolium > S. boveanum with highest Zn concentration of 991 ± 49.1, 988 ± 47.5, 980 ± 44.2, and 911 ± 39.7 μg g -1 dry weights, respectively. In addition, Cu was detected at high concentration of 92.1 ± 3.7 μg g -1 dry weight in S. boveanum. These results clearly indicate the high pollution levels of Al-jubail industrial city coast with Zn and Cu toxic heavy metals, which is mostly due to uncontrolled disposal of industrial waste into coastal area. Furthermore, the consistency of Zn concentrations in all tested brown algae indicated the efficiency of the tested algae, including P. gymnospora, S. angustifolium, S. latifolium, and S. boveanum, for bioaccumulation and bio-monitoring studies of Zn.

“…The similar results were reported by [31] for Cr, Ni and V determined in Cladophora glomerata from refinery sewage lagoon (Bratislava). Levkov and Krstic [33] found that the levels of Co, Cu, Fe, Mn and Zn in Cladophora glomerata reflected their load in the River Vardar, Macedonia, and recommended it as a precise biomonitoring tool for determination and quantification of heavy metal pollution in this river. In [34] the distribution patterns of Ca, Cu, K, Mg, Mn, Na, Ni, Zn and in the green algae Cladophora sp.…”

The levels and compartmentalization of Na, Mg, Al, Cl, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Zn, As, Se, Br, Rb, Sr, Mo, Sb, I, Cs, Ba, La, Ce, Sm, Eu, Tb, Hf, Ta, Au, Th, and U in Phragmites australis (Cav.) Trin. ex Steud., Carex conescens L. and Cladophora sericea (Hudson) Kutzing from the Caucasian coast of the Black Sea-Anapa recreational region was investigated by Neutron Activation Analysis. The study touches upon subject of the sediment-to-plant and root-to-leaf elemental transfer as well as of the influence of anthropogenic pollution on wetland ecosystems in zone of resort. The content of the majority of considered elements was found higher in the belowground organs of P. australis than in the aboveground tissues while a reverse regularity was evidenced for C. conescens. The levels of elements decrease from bottom sediments to aquatic plants with the notable exception of the halogens Cl, Br and I that presented 5 to 100 fold higher content in plants than in sediments. The increased levels of As, Mo, and Sb in some soil and sediment samples most probably indicate the anthropogenic pollution. It recommends them for a continuous monitoring of the same area.
