“…In the past three decades, researchers have focussed attention on the presence of contaminants in the terrestrial and aquatic habitats with emphasis on heavy metals. The reports of Ndiokwere (1984), Ajayi and Mombeshora (1989), Egborge (1991) and Oluwande et al (1983) revealed the presence of heavy metals at varying concentrations in the different investigated water bodies. A few available reports have also discussed the presence of heavy metals in some fish species and related their presence in fish to uptake from the water and/or sediment compartments (Ezemonye 1992;Fufeyin 1994;TawariFufeyin 1998).…”

The composition and distribution of fish in the Ikpoba reservoir were investigated. A total of fifty-seven species of fish belonging to thirty-nine genera and twenty-three families were recorded. Of these, 46 species were recorded at the upstream station, 35 at the reservoir, 24 at the slope and 32 at the downstream station. The percentage compositions were 81%, 61%, 42% and 56% respectively. There were 21 ubiquitous species while the distribution of the other species showed variability indicating effects of habitat condition. Species diversity indices showed that the upstream section was richer, more diverse with species more evenly distributed than the other stations. Heavy metal analysis of the dominant fish species showed higher mean levels than the background levels. Metal contamination factor and bioaccumulation quotient were variable in the fishes and in the stations but followed a ranked order of 3 > 2 > 4 > 1 by station. Comparison of stations using ANOVA revealed a significant difference (P < 0.05) between the upstream and the slope stations.

“…Edema (1993) investigated the heavy metal contents of the shellfishes of the Warri River catchments. Ndiokwere (1984) investigated the heavy metal content of the sediments, algae and the Nigerian coastal waters. Ntekim et al, (1993) reported on the distribution of trace metals in the sediments of the Calabar River, while Oluwande et al (1983) reported generally on the pollution levels in some Nigerian rivers.…”

The concentration of some heavy metals, Ca, Mg, Fe, Zn, Pb, Cd, Cr, Ni, Hg, and total hydrocarbon content (THC) were assessed in the surface waters of a Niger Delta mangrove creek (Buguma Creek). Samples were collected between November 2004 and October 2006 from five stations. The minimum and maximum concentrations of these heavy metals in the creek were 7.21-228.5 mg/l for Ca, 51.18-428.3 mg/l for Mg, 0.01-6.78 mg/l for Fe, 0.010-0.43 mg/l for Zn, 0.01-0.61 for Pb, 0.01-0.11 for Cd, 0.01-1.49 mg/l for Cr, 0.01-2.73 mg/l for Ni, while Hg and the total hydrocarbon content was approximately 0.01 mg/l throughout the study period. The rank profile of metals according to their mean values was Mg > Ca > Fe > Zn > Ni > Cr > Pb > Cd > Hg in the study stations. There was no statistically significant difference (P > 0.05) in the concentration of heavy metals at the study stations. The EDTA hardness depicts hard water condition. The extremely low levels of the toxic heavy metals, Ni, Cr, Pb, Cd, and Hg, and total hydrocarbon content (THC) of <1 mg/l indicate that the water was not polluted.

“…The studies carried out with the use of sea and fresh water algae confirm their practical application not only in biomonitoring of surface waters pollution [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] but also waters phytoremediation [30] and as biosorbents in the effluent treatment process [31].…”

“…Biomonitoring studies with the use of algae have been carried out in, among others, Poland (the Turawa reservoir, the Odra river, Baltic Sea) [14][15][16][17], in Czech Republic (the Dyje river) [18], Russian Federation (12 rivers in the Kola Peninsula, the Yenisey river in Siberia, Lake Baikal, the Sea of Japan) [19][20][21][22], China (the South China Sea waters near the Hong Kong island) [23,24], Portugal (waters of Ria de Aveiro lagoon) [25], Argentina (the lakes in the Andes: Nahuel Huapi, Gutirrez and Moscardi) [26], Uganda (Lake George, a stream near the city of Kampala) [27,28] and in Nigeria (the Niger river) [29].…”

Biomonitoring studies have been carried out in three retention reservoirs located in the Opole Province (southern Poland): Turawa reservoir, Nysa reservoir and Otmuchow reservoir. The increases of concentrations of Mn, Fe, Cu, Zn, Cd and Pb in fresh water algae Spirogyra sp. and sea water Palmaria palmata (Linnaeus) Weber & Mohr, exposed in the analysed waters, were determined by the atomic absorption spectrometry method (AAS). Also the waters pH, conductivity and Mn and Fe concentrations were determined. The concentrations of Cu, Zn, Cd and Pb in the analysed waters were lower than the method limit of determination. The analyses were carried out during the period from June to July 2014. The differences between the increases of heavy metal concentrations in the samples of algae found along the coastline were indicated; they result from different distances from the pollution sources, such as sediments or drainage from the areas adjacent to the reservoirs. Better sorption characteristics of Palmaria palmata in comparison to Spirogyra sp. were indicated. An empirical interrelation was also tested, the application of which after modification may enable the quantitative assessment of waters pollution with heavy metals, based on the analysis of the concentration of the element in the algae thallus.
