LEVEL OF HEAVY METALS IN YAM, CASSAVA AND COCOYAM TUBERS IN NIGER DELTA NIGERIA – A SURVEY

By Udeze Anthoina Ogechukwu

A total of seven heavy metals, Pb, Cd, Zn, Fe, Ni, Cu, Mn, Na, were determined in cassava, yam and cocoyam using atomic absorption spectrophotometer model schimadzu AA 6701 in airacetylene flame. The samples were cut, peeled, washed, sliced very light, air dried and ground into powder. 5g of the powered samples were ashed, digested using 2ml of 36.5g/dm Hydrochloric acid, 2ml conctrioxonitrate (V) acid and distilled water, to remove all the organic matters and leave behind the trace metals. These Endings showed that some metals like Fe (16.23mg/kg in yam), 18.26mg/kg in cassava, 31.36 mg/kg in cocoyam and Zn, 19.77 mg/kg m coco yam have higher values compared with W.H.O standard. The most toxic ones, lead

POLICY FORMULATION FOR E-GOVERNMENT: A STUDY OF NATIONAL INFORMATION TECHNOLOGY DEVELOPMENT AGENCY, ABUJA - NIGERIA

By Ngwaka, Anayo Ambrose

This research study was on Policy Formulation for E-Government in Nigeria: A study of the National Information Technology Development Agency, Abuja – Nigeria. The study adopted survey research design to examine how NITDA could enhance Nigerians readiness in participating in E-government revolution. A research interview scale and a structured research questionnaire were instruments used for data collection; while the subjects of study were the seven (7) principal (policy-making) staff of NITDA. The data generated from the study were analyzed using simple percentage computational, charts and other statistical tools made available for use by the Microsoft Excel workbook. The findings of the study showed that the readiness of Nigerians to take part in the e-government revolution was very high since the enactment of the Nigerian National Information Technology Policy Act of 2001. The research also shows that Nigeria in the Global Village of internet users is ranked tenth (10th) worldwide and first (1st) in Africa and that policy implementation, creation of public awareness and the development of the Mobile Internet Unit (MIU) are some of the remarkable contributions of NITDA to enhance e-government practice in Nigeria. From the findings, the researcher recommends that serious awareness be created by NITDA to stimulate understanding of the Nigerian populace to the e-government policy formulation of the Nigerian Government, using every channel of communication such as the radio, television, newspaper and short message services (SMS). The researcher also strongly recommends frequent updates on the various activities of government ministries and agencies on their websites and to reflect same on the official Nigerian website.
