Dr Nnorom is a Senior Lecturer and holds a BSc in Industrial Chemistry (Abia State University), an MSc in Analytical Chemistry and PhD in Analytical/Environmental Chemistry (University of Ibadan). Presently he has sixty (60) journal publications in highly reputed international journals, and three (3) book chapters in ‘Advances in Environmental Research Series’ of Nova Science Publishers (USA).  He alongside Basel Convention Coordinating Centre for Africa (BCCC-A) Team members contributed a book chapter in the Wiley Interscience Publishers book titled ‘Metal Sustainability: Global Challenges and Consequences’ which was edited by R.M. Izatt (presently in press).

Dr Nnorom has attended several conferences and workshops and presently has about 32 conference/workshop papers/posters. He has two international publications with the United Nations Environment Programme (UNEP) and acts as a reviewer for more than ten (10) international journals, including five (5) Elsevier journals. In 2012 he presented a key note address titled ‘Waste recycling challenges and opportunities in developing countries’ at the 4^th Annual and 2^nd International Conference of Civil Engineering. Main Auditorium, University of Ilorin, Ilorin, Nigeria, (4^th-6^th July, 2012).

 

He has worked as a research fellow/field scientist/consultant with the Basel Convention Coordinating Center for Africa (BCCC-A), the Blacksmith Institute and the United Nations Environment Programme (UNEP). Dr Nnorom participated in the E-waste Africa Project of the Secretariat of the Basel Convention, United Nations Programme (UNEP), the Basel Convention Coordinating Centre for Africa (BCCC-Nigeria), Swiss Federal Laboratories for Materials Science and Technology (EMPA), St.Gallen/Switzerland, and the Oeko-Institut (published in May, 2012 as ‘e-Waste Country Assessment Nigeria’, http://www.ewasteguide.info/Ogungbuyi_2012_BCCC-Empa).

Following his research and publication of an article titled ‘Overview of prospects in adopting remanufacturing of end-of-life electronic products in the developing countries’ Dr Nnorom was invited by Giles Chappell in 2013 to research and make a contribution on manufacturing/remanufacturing in the ICT Sector of Nigeria (Titled: Manufacturing – case study on Nigeria; available at: http://www.unep.org/greeneconomy/Portals/88/documents/research_products/Tradeopportunities/Nigeria%20case%20study.pdf)) for subsequent publication in the UNEP report titled ‘Green Economy and Trade Opportunities’ which was prepared by the United Nations Environment Program, International Trade Centre, and the International Centre for Trade and Sustainable Development. The submission was edited and published as ‘Nigeria – Remanufacturing in the Information and Communication Technologies (ICT) sector’ in the United Nations Environment Programme report on: Green Economy and Trade Opportunities (UNEP; International Trade Centre; International Centre for Trade and Sustainable Development) (http://www.unep.org/greeneconomy/ResearchProducts/GreenEconomyandTradeOpportunities/tabid/104305/language/en-US/Default.aspx Published in: UNEP (2013) Green Economy and Trade: Trends, Challenges and Opportunities, http://www.unep.org/greeneconomy/GreenEconomyandTrade. http://www.unep.org/greeneconomy/GreenEconomyandTrade  (Full document at http://www.unep.org/greeneconomy/Portals/88/GETReport/pdf/FullReport.pdf)

 

 

In 2009, He won an award to represent Africa at the first StEP/NVMP/United Nations University Electronic waste (e-waste) summer school at the High Tech Campus Eindhoven, the Netherlands; the R’09 Twin World Congress, “Resources Management and Technology for Material and Energy Efficiency”, Davos, Switzerland.  Conference convened simultaneously in Davos (Switzerland) and Nagoya (Japan); and the World Resources Forum 2009 (WRF 09), Davos, Switzerland.

He attended the International Telecommunications Union (ITU) 9th World Telecommunication/ICT Indicators Meeting (WTIM 11), as an ITU Expert in Mauritius in 2011 where he presented the first paper on E-waste at any of the ITU meetings.

 

In December, 2014 he attended the African Union Commission (AUC) ‘Parliamentarian Colloquium On Multilateral Environmental Agreements (MEAs) – Biodiversity And Chemical/Waste Clusters’ With Theme: “MEAs, A Vehicle For Environmental Sustainability in Africa” at African Union Commission (AUC) Headquarters , Addis Ababa, Ethiopia, (3-5 December 2014) where he presented a paper titled ‘Overview of E-waste management in Africa’.

 

In September 2015, Dr Nnorom was invited by Professor Jerzy Falandysz to visit the Faculty of Chemistry of the University of Gdańsk (the Laboratory of Environmental Chemistry and Eco-toxicology) to participate in a scientific collaboration on environmental and food toxicology issues in the period from September 1 to September 14, 2015. During his stay in University of Gdansk, Poland, he was invited to present a lecture to the Faculty of Chemistry. He accepted and presented a lecture  titled ‘Electronic waste (e-waste) management in Africa: Challenges and prospects’. (http://chemia.ug.edu.pl/search/node/Nnorom

Dr Nnorom has attended several conferences. In 2015 he attended the XI International Scientific and Technical Conference in Warsaw Poland with the theme “Element Cycle in the Environment: Bio-accumulation, toxicity and prevention” where he presented seven papers. In the same year he attended the XVII Congress of European Mycologists at the Hotel VidaMar, Funchal – Madeira, Portugal from September 20 to September 25 2015 where he presented four papers. His love for mushrooms led to a novel study that profiled the major and minor elements contents of the sclerotium of Pleurotus tuber-regium (osu) which was published in Journal of Food Composition and Analysis. He has been collaborating with the Research Group of Environmental Chemistry, Ecotoxicology & Food Toxicology, Institute of Environmental Sciences & Public Health, University of Gdansk, Poland, since 2010. Jointly the collaboration have studied mushrooms from Nigeria, Poland, Sweden, and Belarus and the outcomes of the joint research have been published in highly reputed journal including Food Chemistry, Journal of Food Composition and Analysis,  Ecotoxicology and Environmental Safety, Journal of Food Science, Bulletin of Environmental Contamination and Toxicology, Journal of the Science of Food and Agriculture, Journal of Environmental Science and Health, Part A. Toxic/Hazardous Substances and Environmental Engineering, Fresenius Environmental Bulletin, Journal of Environmental Science and Health, Part B: Pesticides, Food Contaminants, and Agricultural Wastes, Environmental Science and Pollution Research International

 

Dr Nnorom is a member of the Institute of Public Analysts of Nigeria (IPAN) and the Chemical Society of Nigeria (CSN). He is the present Public Relations officer (PRO) of the Abia State Branch of CSN

Presently he is participating in the “Person in the Port (PiP) Project” jointly performed by the United Nations University (UNU), the U.S. Environmental Protection Agency (US-EPA), and the Basel Convention Coordination Centre for Africa (BCCC) in Nigeria – all members of the Solving the E-waste Problem (Step) Initiative – partnering together with Electronic Recyclers International (ERI) in order to better understand the quantitative and qualitative aspects of used electronics imports into Nigeria. Project aimed at gathering reliable information and data on the importation of used electrical and electronic equipment (UEEE) and waste electrical and electronic equipment (WEEE or e-waste) into Nigeria (via the Lagos ports), one of the key countries in West Africa through which UEEEE and WEEE flows. The project focuses on identifying the types and amounts of UEEE and WEEE imported their origin (exporting countries), their functional status, how they are packaged, labelled and transported, and their fate on arrival in Nigeria.

Areas of Research Interest:

Electronic waste management with emphasis on inventory; remanufacturing, toxicity characterization, of components, pollution with heavy metals resulting from inappropriate management; modeling e-waste generations and flows; trans-boundary movement, and the role of regulation and related issues in achieving sound management of e-waste and, urban mining.

Heavy metal contamination of consumer products and the environment: cosmetics and herbal remedies as sources of heavy metal intake in the population; soils etc. Food Toxicology: assessment of heavy metal contamination of foodstuff, mushrooms, etc and evaluation of heavy metals intake from food stuff such as ukwa, cashew, walnut, nzu, akanwu, ogbono etc.
