“…The elevated enzyme activities found to be concentrationdependent may be linked to oxidative stress caused by glyphosate and paraquat. However, Adeyemi et al (2009b) reported decreases in hepatic activities of alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase after exposing C. gariepinus to sublethal concentrations of phthalate, benzene and cyclohexane for 56 days. These enzymes are distributed differently in different body tissues, which may be a function of the health status of the fish.…”

Direct and indirect contamination of the aquatic environment by pesticides results in a decrease in fish productivity and may elevate concentrations of undesirable chemicals in edible fish tissues. The effects of long-term exposure of Clarias gariepinus juveniles to sublethal concentrations of glyphosate and paraquat, two commonly used herbicides, for eight weeks were investigated using three concentrations of the 96 h LC 50 of each herbicide: 3.5, 7 and 14 µg l −1 for paraquat, and 26.5, 53 and 106 µg l −1 for glyphosate. Enzyme assay and histological analysis were conducted every fortnight. Significant increases in the activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), alkaline phosphatase (ALP) and hepatocyte vacuolation in the livers of the exposed fish confirms the toxicity of the herbicides, and thus could be useful tools in environmental monitoring.

“…Fish used in this study may have had a better health status than those used in the reference study i.e. Adeyemi et al (2009b). Lactate dehydrogenase is also a marker of tissue damage, and its increased level is reported in liver necrosis (Ramesh et al 1993).…”

“…The choking odour was likely to be as a result of anaerobic reactions and this could be due to the high amount of dissolved solids in the wastewater (Onajobi et al, 2013). Going by international standard, any water contaminated to this level is neither good for domestic use, nor is it supposed to be discharged directly into the environment without treatment (Adeyemi et al, 2007). Many of the isolated bacteria from wastewater samples are known pathogenic microorganisms that are potential causative agents of various infectious diseases.…”

Physicochemical properties and antibiotic susceptibility of microorganisms isolated from wastewater samples collected from Al-Hikmah University female hostels were assessed. Samples obtained from different female hostels were examined physiochemically and microbiologically using standard procedures. Phytochemical result revealed the low temperature value of 28°C from Oladimeji and Commaissie hostels, while Deremi and Owaish had a value of 29.5°C. Dissolved oxygen of 0.1 ml/L was recorded from all the samples collected. Electrical conductivity ranged from 658 to 997µs, while chocking odour was recorded in all the four samples collected. In terms of pH, Oladimeji hostel had a pH of 10.5, Deremi had a pH of 10.6, while Owaish and Commaissie had a pH of 10.4. The wastewater samples from the four hostels were highly contaminated. Oladimeji hostel showed a mean bacterial 5count of 25.4×10cfu/ml, Deremi hostel, Owaish hostel and Coomassie hostels, showed a mean 4 4 4bacterial count of 5.7×10cfu/ml,16.8×10cfu/ml and 3.5×10cfu/ml respectively. Percentage occurrence of bacteria isolates were Salmonella sp. (12.5%), Klebsiella pneumoniae (12.5%), Escherichia coli (25%), Staphylococcus aureus (12.5%), Actinomyces (12.5%), Shigella sp. (6.25%), Pseudomonas aeruginosa (12.5%) and Proteus vulgaris (6.25%). Antimicrobial sensitivity tests revealed that all the organisms were susceptible to gentamycin except Actinomyces. High microbial load in wastewater samples could have negative effects on human health. This study, further confirms the need to treat wastewater rather than directly discharging it to the environment.

“…Previous study [ 11 ] had shown that leachate-contaminated groundwater around Odo Iya Alaro landfill in Lagos, the former capital of Nigeria, contains heavy metals such as lead (Pb) and cadmium (Cd) which have been implicated in oxidative damage. The present study examined the probable oxidative damage to tissues arising from the consumption of leachate-contaminated groundwater around Odo Iya Alaro landfill.…”

Some parameters of oxidative stress: malondialdehyde, reduced glutathione, catalase and superoxide dismutase were determined in rats placed on leachate-contaminated groundwater over a period of sixty five days. Significant increase in malondialdehyde (MDA) concentrations is observed in test rats relative to control (p<0.05). In particular, the concentration of MDA in the liver of rats placed on the first well water (14.00±0.5 nmol/mg tissue) was significantly (p<0.05) higher than that of control (12.47±1.2). Conversely, reduced glutathione (GSH) concentration, catalase activity and superoxide dismutase (SOD) activity were significantly lower in test rats relative to the control group (p<0.05). Particularly, the activity of SOD in the liver of rats (0.58±0.01 Unit/mg protein) placed on first well water was significantly (p<0.05) lower than that of rats placed on tapwater (0.90±0.02). From the result, it is probable that consumption of leachate-contaminated groundwater may induce oxidative stress by causing membrane lipid peroxidation.
