Pesticides, including insecticides and fungicides, are major contaminants in the effluent from intensive agricultural systems, such as greenhouses. Because of their constant use persistence, some pesticides can accumulate soil and/or run off into adjacent waterways. Microbial communities degrade pesticides, bioreactors with enhanced microbial have potential to facilitate decontamination before is released environment. In this study, we sampled along a gradient immediately below greenhouses,...
One hundred and twenty normal post juvenile catfish (Clarias gariepinus) of both sexes with a mean weight 135.44±1.99 g length 28.32±0.844 cm were purchased from Osayi farm. They kept in 60 l aquaria at 27.5±0.4 ◦C, pH 7.3, 12:12 h photoperiod, well aerated, provided external filtration layer gravel on the bottom. Histopathological alteration brain tissues when fish exposed to various concentrations (18 mg/L, 32mg/L 75 mg/L) glyphosate for period 7 – 28 days revealed that hervicide may be...
Water pollution, particularly, surface water results from all activities of man involving indiscriminate waste disposal industry such as effluents into waterways, waste, agricultural and forms man’s that in contamination the water. Wastewater samples were collected two (2) carefully selected industries Physico-Chemical parameters analyzed compared to FEPA (Federal Environmental Protection Agency) standard. DO analysis ranged 6.5 – 9.7mg/l, BOD value range 3.2 8.8mg/l, there was no...
Organochlorine pesticides are among the group of agrochemicals with potential for bioaccumulation in fish posing great threat to human health through consumption. In view this, organochlorine pesticide residues (OCPs) were analysed muscle tissue two freshwater species; Alestes baremoze and Synodontis bastiani from selected stations along Warri River, Nigeria, aim assessing risk associated The collected landing sites located at Ovwian Okwagbe communities River. These agrarian catchment areas...
Heavy metal concentrations in tissues and cestode parasite of the African giant rat collected from staff quarters University Benin, Benin City, Nigeria were determined using Atomic Absorption Spectrophotometry (AAS). Possible human health risk associated with consumption contaminated rats was also appropriate intake models. The isolated identified as Inermicapsifer guineensis total infection rate 100%. mean heavy metals (mg/kg) liver ranged 1.82 to 3.98 (Pb), 0.22 0.54 (Cd), 22.14 45.53...
Abstract Imidacloprid is among the most widely used insecticides and may contaminate surface waters, yet there limited information available on their effects fish. In present study, juvenile catfish ( Clarias gariepinus ) were exposed to 100, 130, 160, 190 mg/L of imidacloprid for 96 hours, mortality, behavior, hepatic endocrine functions, oxidative stress, tumor inflammatory responses investigated. The hours LC 50 was 166.60 (143.38-193.59 95% confidence intervals) with mortality recorded...
