Cholesterol esterase (Cease) from bovine pancreas and cholesterol oxidasc (COD) from Bravibacterium recombinant type have been innobilized individually and co-immobilized onto arylamine glass (pore diameter 55nm) through the process of diazotization. Cease and COD retained 92.65% and 85.54% of the initial activity with conjugation yields of 7.2 mg/g and 8.3mg/g support respectively when imnobilized individually on arylamine glass beads, but retained 89.58% of the initial activity with a conjugation yield of 2.9 mg/g support when co-immobilized on the same support. The effects of pH, temperature, time of incubation, substrate concentration, serum inorganic salts & metabolites, thermal stability, storage stability in cold and reusability on the immobilized enzymes were studied and compared with those of free enzymes. The analytic use of both individually immobilized and co-immobilized enzymes in discrete analysis of total and free cholesterol in serum is demonstrated.

Geochemical assessment of groundwater samples from hand-dug wells within the vicinity of Aba-Eku dumpsite was carried out for domestic and irrigation purposes. Ten groundwater samples were collected both in dry season and wet season for analysis of physico-chemical parameters: pH, EC, TDs,The results of the analyses showed the groundwater samples to be within limits of WHO/NsDWQ. However, higher values of concentrations of the chemical constituents were noticed in well 5 nearer to the landfill. Interpretation of Piper diagram showed CaHCO3 to be dominant in the area. Alkaline earth metals ?and weak acids ?are dominant cations and anions over the alkalis and strong acids in both sessions. Groundwater in the study area is of hard, fresh and alkaline nature. Assessment for irrigation purpose showed that most of the water samples were suitable for irrigation purpose except in a few locations.
