Drinking contaminated groundwater can have serious health effects. Bacterial assessment of groundwater in Ekiti State was carried out to determine its potability and source(s) of pollutants. Consequently, 73 groundwater samples were collected for bacterial analysis and NO3 determination. At each location, depth of each well and depth to water table were measured using dipmeter. Temperature (°C)...

Water is used for various human activities such as drinking, bathing, washing and recreation. The physicochemical as well as microbiological qualities of water samples collected over a period of ten months from five swimming pools in five randomly-selected hotels in Osogbo metropolis, Southwestern Nigeria were assessed. The collection of the fifty water samples spanned the dry and rainy seasons...

BACKGROUND Water-related diseases are of great concern in developing countries like Nepal. Every year, there are countless morbidity and mortality due to the consumption of unsafe drinking water. Recently, there have been increased uses of bottled drinking water in an assumption that the bottled water is safer than the tap water and its use will help to protect from water-related diseases. So, ...

Raw goat milk is recognized as one kind of nutritious food owed to its originality and medicinal values. This study aimed to evaluate the physico-chemical and microbiological qualities of locally produced raw goat milk prior any processing steps during storage. Milk samples passed organoleptic test and C.O.B. test were mostly (88.89 %) failed in alcohol test. AOAC Official method of oven drying...

the mediterranean flour moth, ephestia kuehniella zeller, is one of the major pests in stored products worldwide. several problems assossiated with the use of conventional insecticides have strongly demonstrated the need for applying alternative safe compounds such as insect growth regulators (igrs). in the present study, growth regulating activity and hematological effects of pyriproxifen and ...

Four brands of membrane filters were examined for total and fecal coliform recovery performance by two experimental approaches. Using diluted EC broth cultures of water samples, Johns-Manville filters were superior to Sartorius filters for fecal coliform but equivalent for total coliform recovery. Using river water samples, Johns-Manville filters were superior to Sartorius filters for total col...

This method relies on the RELATIVE COMPARISON between numbers to formulate a diagnosis. (Examples of this are presented in the appendix). The most common misapplication of the method is the formulation of a diagnosis based on only one of these numbers without considering the relative values of the others (a high LPC count does not always indicate a cleaning failure). As indicated in the interpr...
