Assessment of water, sediment and crab (Callinectes amnicola) contamination by heavy metals IN Ijala creek, Ekpan, Delta state, Nigeria

Heavy metals such as; Nickel (Ni), Lead (Pb), Chromium (Cr), Iron (Fe), Cadmium (Cd), Manganese (Mn), Zinc (Zn), Copper (Cu) and Vanadium (V) were assessed in water, sediment and crab (Callinectes amnicola) from three stations along Ijala creek. The creek receives effluents discharges from Industrial activities and few human settlements within the area. Samples of water, sediment and crab (Callinectes amnicola) were...

Comparative study of heavy metal concentration of Rivers Niger, Benue and the confluence points for sustainable fish production in Lokoja, Kogi State

The different levels of some heavy metals content of Rivers Niger, Benue and their confluence points were determined and compared for one calendar year from April 2016 to March 2017. Five sampling stations were located along River Niger, River Benue, Confluence point and their post Confluence Points. Two water samples were collected from each of the station once monthly and analyzed. The result of the analyzed data showed...

Effect of exposure to sub-lethal potassium cyanide (kcn) on growth rate, survival rate, and histopathology in juvenile heteroclarias (Heterobranchus longifilis♀ x Clarias gariepinus♂)

Experiments were conducted to determine the toxicity of potassium cyanide (KCN) on juvenile Heteroclarias following a 96h static renewal bioassay method. Test specimens were acclimatized for 21-days prior to their exposure; the acute toxicity (LC50) was determined to be 0.96 mg/L. Fractions of LC50 (1⁄5, 1⁄4, 1⁄3 and ½) in triplicates were estimated for sub-lethal studies in a 21-day exposure/ recovery periods. Toxicity of...

Statistical modelling of the response fate of spent-engine oil contaminated soils to bioremediation strategy

Bioremediation of contaminated soil by biostimulation strategy enables indigenous microorganisms in the soil to biodegrade contaminants by utilizing nutrients added to the soil. This study attempts to investigate the optimum nutrients required for bioremediation of spent-engine oil contaminated soil using Box-Behnken Design under response surface methodology. Three concentration levels of cow manure, poultry manure and...

Heavy metal contamination of aquatic ecosystems has been recognised as a serious pollution problem.. In the present study an attempt has been made to estimate the accumulation of heavy metals like iron, chromium, copper, cadmium and lead (Fe, Cu, Cr, Cd and Pb) in water samples as well as in the fish sample, (Mystus gulio) in Vattakkayal, Ashtamudi lake, Kollam district, South India. Heavy metals in water are particularly...

A Review of Impacts of White Pollution on Aquatic Environment

Aquatic environment is undoubtedly important to human existence and it constitutes the largest portion of the earth surface. White pollution is a major global threat to the environment, causing impairment of its structure and function, ultimately with adverse effect on man. Many forms of human activities has continued to introduce plastic waste into the global waters since the inception of “plastic age”, causing disruption...

Comparative Assessment of the Environmental Dynamics of Dissolved Organic Carbon and characterisation of DOM in Subtropical Wetlands of some Northern Nigerian States.

This study focuses on the comparative assessment of the environmental dynamics of dissolved organic carbon in subtropical wetlands. DOC was determined using persulphate UV-visible spectrophotometric method. The averaged values for DOC during the one-year samplings ranged from 7.454±0.73 to 13.686±1.50 mg/l, in the wetlands studied. These values are above the 4 mg/l, limits set for DOC in water. SUVA values in the wetlands...

Assessment of copper levels along the Namibian marine coastline

Elevated trace metal in the aquatic environment is a global challenge. In this investigation, copper (Cu) levels were assessed using inductively coupled plasma optical emission spectrometry (ICP-OES) during winter and summer months of 2012. The aim of this study was to determine the pollution status of Central Namibian coastline using copper levels in black mussel, sediments and water as indicators. Results indicated that...

Monitoring of Heavy Metal Levels in High Traffic Areas and Abattoirs in Benin Metropolis, Nigeria

Increasing reports of Pollution of soils of high traffic areas and abattoirs all over the world with heavy metals have become worrisome. This study assessed the heavy metal contamination of soils of selected urban high traffic areas (HTAs) and abattoirs in Benin metropolis. A total of 168 soil samples were collected along high traffic density areas and abattoirs with 84 samples each from sample locations a period of 6...

Study on the Reduction of Properties of Wastewater Using Water Hyacinth

Industrial sewage management is a serious issue in most of the cities in developing countries. Though many physio – chemical techniques have been set up, they seem to be expensive and laborious. Hence, it is necessary to find a simple low cost - effective treatment method for removing the pollutants in the water. In the present study, an investigation is conducted on dry water hyacinth and its biosorption property on waste...

Antialgal properties of Zinc oxide nanoparticles (ZnO) on different freshwater algae

Abstract The toxicological risk of such metal oxide nanoparticles in the environment is hard to evaluate due to a lack of knowledge on the mechanisms of these nanoparticles interaction with biological systems. In this study, we investigated the effect of nano-ZnO on three different freshwater blue green algae such as Microcystis sp., Anabaena sp. and Tribonema sp. Nano-ZnO had a negative effect on freshwater aquatic algae,...

Haematological and Biochemical changes in Clarias gariepinus exposed to sub-lethal concentrations of Water Soluble Fractions of Crude Oil

The effects of water soluble fraction (WSF) of crude oil from Afiesere oil field on haematological and biochemical parameters in juveniles of Clarias gariepinus were studied. The 96 h-LC50 of crude oil determined by probit regression was 224.74mg/l. Fish were exposed to 4 sub-lethal concentrations (30, 45, 60 and 75% of the LC50 corresponding to 67.42, 101.13, 134.84 and 168.56 mg/l respectively) of the oil and a control....
