Both communities are oil-producing communities and agriculture constitutes the primary income generating activities of the indigenes. A 15 item close-ended questionnaires was used to elicit responses from 100 animal, crop and fish farmers. This sample was made up of 55 and 45 farmers randomly drawn from Edjeba and Kokori communities respectively. The results showed that oil exploration and production activities have caused damage to farmlands and water bodies as a result of oil spillage leading to a decrease in agricultural output and hence the income earning capacity of the people has declined appreciably. The results also showed an increase in the occurrence of health hazard, air/noise pollution and heightened deforestation in these communities. It is recommended that regular inspection of oil pipelines, monitoring of oil fields, adequate and timely compensation payments, provision of farm inputs including agricultural extension services and improved seeds be made available to host communities for improved agricultural production.

The insects are: ant ( Psilocephala aldrichi conquillet ), lady bird beetle ( Hyppodamia convergen ), honey bee ( Apis mellifera ), woodroach ( Parcoblatasp ), cockroach ( Blatta orientallis ), housefly ( Musca domestica ), dung beetle ( Canthon pilularis ) and wood cricket ( Nemobius sylverstris ). From these Insects, fourteen bacteria and thirteen fungi species were recovered and identified. The internal part (gut) of the insect-pests were found to contain more bacterial load than the external part while fungal load was more on the external parts than the internal. Among the identified insect-pests, Canthon Pilularis was found to be more implicated of harbouring bacteria while Nemobius sythestris harbored more fungal load than other. Musca domestica had the highest population of 61.5% while Hypodamia convergen had the least of 0.6%. However, the recovery of microorganisms from the insects in the surveyed refuse, highlights microbial presence and species in the environment where they were collected. There is of course the tendency of these insects contaminating foods and other materials to effect transmission of disease(s) to man, animal and plants.

Such use may be for drinking and other household needs, industries,livestock rearing or fisheries etc. poor quality water is commonly treated to ensure potability. Potable water should be free from unpleasant tastes and odour, have a good appearance and be suitable for domestic as well as a wide range of industrial purposes. Continuous statistical distributions are usually applied to engineering situations. A goodness-of-fit test is usually necessary to determine the fitness of a distribution to specific data. The Kolmogorov-Smirnov test which is a widely used goodness-of-fit measure was used in the work. A total of four continuous distributions namely normal, log normal, gamma and weibuill were employed for data obtained from effluents of coagulation/clarifying process, (settled water), filtration (filtered water) as well as chlorination process (final water). For the settled water, colour and turbidity are lognormally distributed while pH is normally distributed; filtered water has colour, turbidity, free chlorine and total chlorine log normally distributed while pH has gamma distribution for best fit. The log normal distribution fitted all the parameters undertaken for the final water.

The population of this study comprised the total number of 620 household heads in the six communities. The primary objective of this study was to investigate factors responsible for high poverty rate in the rural areas that has made the application of forest management policies unworkable. Analysis of data from the 150 sampled household heads in the study area revealed that the level of poverty and general standard of living in the study area are highly deplorable, leading to high rate of forest exploitative drive. The study further indicated that majority (68.67 percent) of the sampled respondents had no gainful employment, hence the propensity for forest resource exploitation. It showed further that about 77.33 percent of the sampled respondents were ignorant of the forest bye-laws. Based on these findings, it was recommended that the rural people in the study area should be empowered to take active part in sustainable management of the forest as this would help to reduce the level of poverty. Also other sources of income and nutrition (example, fish and snail farming) apart from forest resources should be developed and encouraged.
