This study investigated and compared the glycaemic rises following administration of various honey samples in rats. Five Nigerian honeys [Abakaliki honey (ABH), Calabar honey (CAH), Ezzamgbo honey (EZH), Lokoja honey (LOH), Okitipupa honey (OKH)] and one Malaysian honey (MAH) were administered to non-diabetic and alloxan-induced diabetic rats. Fasting blood glucose (FBG) concentrations were measured at 0, 30, 60 and 120 min. Glucose parameters including peak blood glucose, area under curve, percentage variation in blood glucose (BG) and percentage change in BG were estimated.

Refuse dumpsites often contain materials capable of polluting surrounding soils. In this study, the spatial distribution of metals in soils of refuse dumpsites in three urban towns (Ughelli, Sapele, Orhuwhorun) in Delta State, Nigeria were examined. Soil samples were collected from three dumpsites in the aforementioned towns at depths 0-15 cm, 15-30 cm and 30-45 cm, respectively.

The Falcorp mangrove swamp has and is still been exposed to various forms of anthropogenic polluting activities which include; Vandalization of oil pipelines which transverse sections of the swamp. The PAHs and PCBs profile of swamp sediments was investigated. The sediments were subjected to routine PAH and PCB analyses which included; extraction, use of sonicator, GC-ECD and GC-FID analysis. The data were subjected to statistical and multivariate analysis using Microsoft Excel, SPSS version 16.0 and PAST respectively.

Polybrominated diphenyl ethers (PBDEs) are a class of synthetic halogenated organic compounds used in a number of polymer-based commercial and home-use products. They are incoporated in the manufacture of electronics devices, furniture and textiles to increase resistance to flames and to meet set out fire safety standards. Generally, PBDEs are characterized by long range atmospheric transport, high bioaccumulation and toxicities. There is a dearth of information on the concentrations of PBDEs and the pattern of distribution at the various e-waste dump and dismantling sites in Nigeria.

Participatory rural appraisal surveys aimed at determining farmers’ perception of plantain production constraints in Port Harcourt metropolis (specifically at Rivers State University [RSU], Nkoplu and the Agricultural Development Programme [ADP] farms, Rumuodomaya) have revealed: poor soil fertility, wind, “drought” and “disease” (in that order of importance) as the major militating factors to plantain (or Musa) production in this region.
