Abstract The concentrations of polychlorinated biphenyls (PCBs) in sediment samples from the New Calabar River in the Niger Delta Region of Nigeria were determined. Grab sediment samples were collected from five stations in the river and analyzed for individual PCB congeners using gas chromatography - mass spectrometer. The Σ8PCB (sum of eight congeners) identified in the samples ranged from 0.21 to 2.16 mg/kg. Congener 105 and 194 were the most and least abundant with 34.65 % and 2.46 % respectively. The lower chlorinated congeners (below PCB 101) were prominent with 54.68 % of the total PCBs concentration in the sediments. The results of this study should make PCBs contaminants of grave concern in the Niger Delta Region.

This study sought to investigate factors militating against community participation in development projects executed under the Micro Projects Programme and how to reduce such factors to the barest minimum in the Niger Delta region of Nigeria. A cross-sectional survey design was adopted for the study. A questionnaire, an in-depth interview (IDI) guide and a focus group discussion (FGD) guide were used for data collection. Borehole water, generator-house, health centres, staff quarters and markets were the projects executed. Inadequate devolution of power to the grassroots, among others, was the major problem that hindered involvement of community members in the development process of the Micro Projects Programme in the study areas. To enhance active participation of beneficiaries in the development process of the programme, suggestions are proffered.
