Abstract
Air sampling was carried out on the research area (Eagle Island) using both experimental and Gaussian dispersion model. A DM 106(particulate mass monitor) was applied to deduce the concentrations of suspended particulate matters (PM 1, PM 2.5, PM 10). Also, concentrations of pollutants (NO2, VOCs, SO2) were obtained using an Aerqual 300 device, while temperature, humidity, wind speed and wind direction were measured using Portable extech 45156 weather station and compass with experimental values obtained for two days (morning and night). Thus, these experimental concentration values obtained was plotted showing level of concentration at different locations (distances). In addition, Gaussian dispersion model was used to predict pollution concentration at various distances to ascertain the level of pollution within the research study area. Modeled results obtained was compared with experimental values to evaluate deviations, and a GIS based model (ARCGIS) was used to determine the general mapping of the research study area with dispersion of pollutants from source to distance up to 1000m depicted.

Research Methods Particulate Matters (PM1, PM2.5, PM 10) Data Collection: A DM 106 particulate mass monitor was used to measure the particulate mass matter, and equipment was held at 1.5m above ground level, ensuring the efficiency of the machine by detecting what an average human can inhale at that height and avoiding dust storm from the ground
The activities of artisanal refineries have contributed to the environmental degradations and pollution of Port Harcourt city as whole with its harmful and degradation effects on the ecosystem of the city
Summary
The upsurge of oil theft in the Port Harcourt metropolis in recent times is alarming. Oil theft and illegal bunkering activities in the Port Harcourt pose a challenge that threatens the very foundation of the oil industry and national economy [1]. Air pollution is the introduction of chemicals, particulate matters or biological materials from such illegal bunker to the atmosphere. This air pollution causes damage to the natural environment or built environment into the atmosphere. It can be defined as the presence in the outdoor or indoor atmosphere of the one or more gaseous or particulate contaminations in quantities, characteristics and of duration such as to be injurious to human, plant or animal life or to property, or which unreasonably interferes with the comfortably enjoyment of life and property [5]. It has been difficult to achieve cooperation for air pollution control in developing countries like Nigeria, whose main concern is to provide such basis need as food, shelter and employment for her populace [1]
