“…For Biochemical oxygen demand (BOD), it ranges from 0-962.5mg/l and the mean was 243.69mg/l. This is above the accepted LASEPA standard for wastewater; moreover, high Biochemical Oxygen Demand values at the discharge point could be attributed to the low Dissolved Oxygen level, since low Dissolved Oxygen will result in high Biochemical Oxygen Demand and this is a strong indication of pollution (Tekenah et al, 2014). The chemical oxygen demand of the wastewater samples ranges from 0-3850mg/l and its mean value is 974.75mg/l which is also above the accepted LASEPA standard for wastewater.…”

“…It reduces the potential of water as a resource; this is because pollution causes the water to become unsuitable for various uses and also makes it difficult and more expensive to treat to acceptable quality for use (Terrumun and Oliver, 2015). Wastewaters are usually released from abattoirs directly into the ecosystems without adequate treatment process thereby posing serious threats to surface water quality, general environmental safety and health (Tekenah et al, 2014). Such water pollution disturbs the balance of the ecosystem, resulting in the death of various animal and plant species present in the water.…”

Direct discharge of abattoir effluents into water bodies contributes to problem of water pollution. This study assessed the impact of Kara Abattoir effluents on Ogun River in Nigeria using standard methods to measure the physiological characteristics and heavy metal levels. The results made it evident that most of the chemical parameters in this study exceeded the accepted standards; phosphate was seen to range between 0.34-109mg/l with a mean value of 27.62mg/l. All the twelve heavy metals observed in the water samples were within acceptable limits. The most alarming result observed is the presence of a "too many to count" range of microbial load and faecal coliform which can be attributable to a major cause of diarrhoea, urinary tract infections, respiratory illness and other threat to human health. Ogun River serves as habitat to some organisms; and is also used for domestic activities by nearby communities; hence, urgent policy implementation is required.

“…Abattoirs situated around Ikpoba river discharge their effluents into the river which is a common practice in Nigeria. A similar situation of abattoir discharge into a watercourse has been reported (Tekenah et al, 2014). Untreated abattoir effluents release high organic load which can cause deoxygenation of rivers, pollution of ground waters, severe health risks and other environmental hazards (Uwidia et al, 2017).…”

Abattoir effluent quality assessment is essential in providing sustainable water resource management developments. This study was carried out to assess the impact of abattoir effluent discharges on the physicochemical qualities of a receiving watershed in an urban community. Some physicochemical indicator variables of the effluent discharge and the receiving watershed were determined using standard analytical procedure. Ranges of values obtained from the study were: pH ( 5.79 ± 0.66 -6.58 ± 0.46), electrical Comparative correlation analysis of the effect of abattoir effluents on the receiving watershed from the studied locations revealed significant positive and negative correlations at probability value (p-value) of 0.05 or 0.01. The study revealed that the effluents discharged from the abattoir facilities pose serious health and environmental risk to communities which rely on the receiving watershed as primary source for domestic or recreation activities.Keywords: Abattoir effluent; Pollution; Aquatic environment; Waste disposal; Water quality isoken.igbinosa@uniben.edu ABSTRACT 219

“…Studies have shown that abattoir solid wastes and effluents contaminated rivers contain high concentrations of hazardous trace metals such as Zn, Cu, Cr, Fe, Cd, and Pb [1,3,4] and high microbial loads [1,2]. However, studies assessing the genotoxicity and cytotoxicity of abattoir effluents using micronucleus test in aquatic vertebrates are relatively scarce.…”

The cytogenotoxic potential of abattoir effluent from Bodija, Nigeria, was investigated using micronucleus test in Clarias gariepinus. Fish was exposed to five different concentrations: 0.2, 0.4, 0.8, 1.6, and 3.1% of the effluent for 7, 14, and 28 days. Tap water and 0.02 mL/L of benzene were used as negative and positive controls, respectively. Physicochemical parameters and heavy metals were analyzed in the effluent in accordance with standard methods. After exposure, blood was collected from the treated and control fish and slides were prepared for micronuclei (MN) and nuclear abnormality evaluation in the peripheral erythrocytes. The effluent induced significant ( < 0.05) increase in the frequency of MN in a time dependent manner. Similarly, the frequency of total nuclear abnormalities (blebbing, notch, bud, binucleation, and vacuolation) was higher in the exposed fish than the negative control. Electrical conductivity, nitrate, biochemical oxygen demand, chemical oxygen demand, arsenic, and copper analyzed in the effluent may have provoked the observed cytogenetic damage. The findings herein suggest the presence of clastogens and cytotoxins in Bodija abattoir wastewater which are capable of increasing genomic instability in aquatic biota.
