“…Heavy metals have been used as indices of pollution because of their high toxicity to human and aquatic life (Omoigberale and Ogbeibu, 2005). Mombeshora et al (1981), Atuma and Egborge (1986) and Edema (1993) associated the high concentrations of heavy metals in the aquatic ecosystems with effluents from industries, refuse and sewage.…”

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.

“…Low heavy metal concentration have been reported in Nigerian water bodies by earlier workers, notable among which are Obire et al (2003) on Elechi Creek, Chindah and Braide (2004) on lower Bonny River, Omoigberale and Ogbeibu (2005) on Osse River, Southern Nigeria.…”

“…Their community assemblages vary in time and space and their diversity within a certain area is related to water fertility and productivity (Latha & Thanga, 2010). Biomonitoring studies employing macroinvertebrates to rate the quality of both lotic and lentic water bodies have been widely reviewed (Ogbeibu & Oribhabor, 2002;Clarke et al 2003;Imoobe & Ohiozebau, 2009;Omoigberale & Ogbeibu, 2010;Birk et al 2012 andDirisu, 2012). The ecological assessment of aquatic systems with macroinvertebrates is one of the most frequently used protocols for water quality evaluations in standard water management.…”

Efficiency of Pollution Tolerance Index (PTI) of macroinvertebrates in detecting aquatic pollution in an oxbow lake in India

This paper evaluates the efficiency of a macroinvertebrate-based Pollution Tolerance Index (PTI) in detecting aquatic pollution in the Chhariganga oxbow lake in India. In this lake, calculated PTIs were compared with results from an array of physicochemical water and sediment parameters and to a macroinvertebrate diversity assessment conducted in parallel for the same lake. The obtained PTI values fell in a range (between 20 and 31) that are indicative of an absence of organic pollution according to the literature, and are normally reported for systems devoid of anthropogenic activity (for instance no monsoonal polluting jute retting activities). However, in the light of the results for the assessed water and sediment physicochemical parameters, and the support of diversity indexes of macroinvertebrates, using data from the same lake, it was possible to conclude that the obtained PTI values do not reflect the true pollution status of this oxbow lake. As PTI values and diversity indexes contradict each other in detecting pollution, it is advised to take both parameters into consideration when using macroinvertebrates to assess aquatic health.
