Application of Hazard Analysis and Critical Control Points of Some Commercial Fish Species Smoked at Various Locations Around Shiroro Lake, Nigeria

ABSTRACT Application of Hazard Analysis and Critical Control Point (ITJ\CCP) of seven species of smoke fish at various locations around Shiroro Lake were evaluated. A Traditional Smoking Kiln and an Improved Traditional Smoking Kiln (control experiment),. This experiment was carried out for a period of sixteen weeks, using six hundred and seventy two(672)samples, sensory evaluation, proximate analysis, microbial identification, heavy metals and and Poly Aromatic Hydrocarbon in thesmoked seven...

The impact of working ton industrial effluent on the surface water quality of marimba river, Harare, Zimbabwe.

ABSTRACT Pollution of water bodies due to human activities such as industrial waste disposal is a serious challenge facing most developing countries in the world today. Thus the management and supply of freshwater to the public is compromised and the ecological integrity of these rivers is lost due to adverse impacts such as eutrophicaton with algal blooms proliferating in these rivers. This could be due to such factors as pre-treatment costs, costs of having pre-treatment plants and in...

Origin and mechanisms of high salinity in Hombolo Dam and groundwater in Dodoma municipality Tanzania

Abstract The Hombolo dam (HD), in central Tanzania, is a shallow reservoir characterized by high salinity that limits its use for human activities. The origin of the salinity, mechanisms of reaching and concentrating in the dam remain unclear. These were assessed using hydrogeochemical facies, water type evolutions and mapping. The source of HD salinity was identified to be shallow groundwater (SG) and runoff from a seasonal floodplain with NaCl-rich lithological materails, along Little...

QUALITY ASSESSMENT OF ABATTOIR EFFLUENT ON SURFACE WATER IN AKURE SOUTH, ONDO STATE, NIGERIA

ABSTRACTWater quality is very important in the environment, because life depends on this, it's very good to check the quality of water time to time to check the rate at which it is been degraded. The objective of this work is to determine the physiochemical and heavy metal parameter of abattoir effluent to surface water and compare the standard to WHO. Two empty bottles were used to collect sample from the surface water, GPS was used to get the geographical coordinate and samples were taken t...

STATISTICAL ANALYSIS OF RAINFALL CHARACTERISTICS IN AKURE, ONDO STATE.

ABSTRACTThis study examines the trends, onset, cessation and growing season of rainfall over Akure using data obtained from the archive of Nigerian Meteorological Agency (NIMET) Oshodi, Lagos, over the period of 1970-2005. Standardized Precipitation Index (SPI) was estimated from the available Rainfall records, Decadal analysis of Akure indicated 1991-2000as a wet decade, while 1981- 1990 was a dry decade. The onset and cessation dates were determined. The estimated parameters were subje...

GEOSPATIAL ASSESSMENTS OF HYDROLOGICAL IMPACTS OF FLOOD OCCURRENCES IN ADO-EKITI AND ENVIRONS

ABSTRACTFlood risk assessment is an important component of risk management. This study aims to generate a GIS-based flood risk map that can facilitate proper planning of mitigation measures against future floods occurrences. This study uses GIS technique and remotely sensed data to assess the extent of urbanization in land use, and vegetation changes in Ado-Ekiti metropolis between 1986 and 2017. Digital Elevation Models (DEM), settlement maps and satellite imageries to assess the susceptibil...

GEOSPATIAL ASSESSMENTS OF HYDROLOGICAL IMPACT OF FLOOD OCCURRENCES IN ADO-EKITI AND ENVIRONS

ABSTRACTDrought is one of the a resultant effect of climate change and it is the naturally occurring phenomenon that exists when precipitation has been significantly below normal recorded levels, causing serious hydrological imbalances that adversely affect land resource production systems. Unlike many other natural hazards, drought develops slowly, making it difficult to pinpoint the onset and termination of an event.The environmental impacts of hydrological drought are Reduced stream flow a...

APPLICATION OF THE STANDARDIZED PRECIPITATION EVAPOTRANSPIRATION INDEX (SPEI) IN BENIN-OWEN A RIVER BASIN, NIGERIA

 ABSTRACTPrecipitation deficit and its daily, seasonal and annual oscillations are inherent characteristics of Nigeria's climate. Droughts are generally characterized by a prolonged and abnormal moisture deficiency. In drought studies it is important to characterize the start and end of a drought as well as its intensity, duration, frequency and magnitude. The objective of this study was to apply the Standardized Precipitation Evapotranspiration index (SPEI) for drought assessment in the...

ASSESSMENT OF POTENTIALLY TOXIC ELEMENTS IN HAND DUG WELLS AND BOREHOLE WATER IN IKOLE-EKITI AND ITS ENVIRONS, EKITI STATE, NIGERIA.

ABSTRACTWater is an important resource for almost all human activities like agriculture, industry, transportation, domestic uses and the proper functioning of the human body, The study examined the physiochemical properties and potentially toxic metals in hand-dug wells and boreholes in Ikole Ekiti and its Environs. Six functional hand-dug wells and six boreholes in the area were sampled and analyzed using standard procedures. Potential toxic metals were determined using Atomic Absorptio...

CHEMICAL COMPOSITION OF BOREHOLE WATER IN TWO LOCAL GOVERNMENT AREAS OF ONDO STATE WITH SPECIAL REFERENCE TO POTENTIAL TOXIC METALS

 ABSTRACTMany households are used to the construction of shallow wells, but the wells hardly provide adequate water supply in term of volume and quality throughout the year. As a result, government adopted the construction of boreholes as an alternative to pipe-borne water supply and as an immediate solution to water supply and quality problem. Groundwater (borehole water) samples were collected randomly from two (2) Local Government Areas: Akure south (Oda, Ijoka, Sebi, Kajola, Ija...

RAINFALL DISTRIBUTION AND THE LENGTH OF GROWING SEASON IN NORTHERN NIGERIA

 ABSTRACTThis study examines the rainfall distribution and the length of the growing season in Northern Nigeria using the daily rainfall data from the selected stations Gasua, Kaduna, Kano, Katsina, Maiduguri, Potiskum, Sokoto, Yelwa, Zaria. The data were collected from the archives of the Nigerian Meteorological Services, Oshodi, Lagos. The length of the growing season was determined using the cumulative percentage mean rainfall method. The growing seasons in Gasau, Kaduna, Kano, Katsin...

PHYSIOCHEMICAL AND MICROBIAL CHARACTERISTICS OF SACmT WATER SOLD IN ADO-EKITI

 ABSTRACTThis study focus on the physiochemical and microbial characteristics of pure water sachet in Ado-Ekiti. A total of sixteen pure water sachet from sixteen brand were collected at random and their physiochemical and microbial parameters were analysed The colour, taste, odour, turbidity, temperature, pH, electrical conductivity, total dissolved solids, total hardness, chloride, sulphate, nitrate, phosphate. and microbial parameters of the stored samples were analysed ,turbidity of ...

THE SANITARY ASSESSMENT AND PHYSIO-CHEMICAL CHARACTERISTICS OF HAND-DUG WELLS IN ADO-EKITI, EKITI STATE, NIGERIA

 ABSTRACTThe study investigated the sanitary assessment and physiochemical characteristics of hand-dug wells in Ado-Ekiti, Ekiti State, Nigeria with a view to support the operation and maintenance of hand-dug wells by providing clear guidance for remedial action to protect and improve water supply in the study area. The town was zoned into ten areas and 50 wells were randomly selected for sanitary risk assessment using the sanitary inspection forms and ten water sampl...
