Four […]

Bacteriological quality of municipal borehole waters in Imo State, Nigeria

Bacteriological quality of municipal borehole samples in Imo State, Nigeria was carried out over a period of 4 months using standard bacteriological methods. The result revealed the total heterotrophic and coliform counts ranges of 3.0 x 101 – 9.6 x 103cfu/ml and 0 – 5.0 x 103 cfu/ml, respectively. The highest total heterotrophic and coliform […]

Seasonal variation in bioavailability of some toxic metals in waste dump soils of Makurdi, North-Central Nigeria

Seasonal changes in the bioavailable forms of cadmium (Cd), copper (Cu) and lead (Pb) in waste dump soils of a rapidly expanding city were assessed by sequential chemical extractions. Three major waste dumps at Apir Mechanic Village (AMV), Benue Industrial Layout (BIL) and Integrated Waste Dump (IWD) all located in Makurdi, north-central Nigeria, were selected […]

ECG findings in young Nigerian medical students

Cardiovascular diseases are becoming more frequent occurrence in the third world. There are tell-tale signs that can be seen long before they occur. Thus forty volunteer medical students, comprising of 18 females and 22 males between the ages of 18 and 30 years, were assessed for cardiac fitness using ECG. All the volunteers were subjected […]

Physicochemical and microbial characterization of somberiro river in ahoada east local government area, Rivers State, Nigeria

A total of six water samples collected at three different stations from Somberiro River were analyzed for the physico – chemical and bacteriological parameters. The physico – chemical parameters recorded highest concentration in site A except in conductivity while Phosphate, Potassium and Nitrate were found higher in site C and site B recorded highest in […]

Seasonal variation and relative abundance of drainage breeding mosquito species in Imo State, Nigeria

An ecological study of drainage – breeding mosquito vectors was conducted in the three urban centers (Owerri, Orlu and Okigwe) of Imo State, Nigeria. Twelve drainage sites located around markets, residence, streams and hotels were selected in each urban centre. Dipping method of sampling was employed and a total of 8,820 mosquitoes comprising eight species […]
