“…Most fresh water resources in the area are linked to estuarine from where they emptied into the Ocean. The activities of makeshift oil refinery on Nun River estuary is having impact on the physicochemical characteristics of water, 50 sediment 51 and macro-invertebrates 52 leading to severe impacts on mangroves plants and macro-invertebrates (such as Marphysa, Lumbrinereis, Lillyalla, Mandippi species, Marphysa sanguinae, Notomastus latericeus, Marianida pinniger, Littorina anguilifera, Neritina owenensis, Pachymelania aurita, Pachymelania bryonensis and Crassostrea gasari etc). 52 In the Niger Delta, several macrophytes have been reported in surface water including Eichhornia crassipes, Nymphaea lotus, N. maculate, Pistia stratiotes, Salvinia nymphellula, Azolla pinnata var africana 16,45,48,53 among others.…”

The Niger Delta region has several ecosystems that play essential role for the sustenance of the different habitats and life forms in the area. Some of the notable ecosystem includes freshwater swamp forest, lowland rainforest, mangroves forest etc. In recent time, the rate of deforestation, excessive hunting of wildlife, bush burning, and intensive agricultural practices has increased in the region. This study reviews the potentials and threats of Niger Delta ecosystem region of Nigeria. The study found that the rate of deforestation and other human activities in the area is having an impact on the various ecosystems in the Niger Delta. These impacts could be affecting biodiversity of the area including mammals, reptiles, amphibians, birds, etc with regard to species diversity and population status. Furthermore, other role played by the various ecosystem including source of medicinal plants, spawning ground for fisheries, breeding and nestling ground for migratory birds, shoreline protection, habitats for wildlife, among others are under intense threat. Therefore, there is the need for improved enforcement, surveillance of the various the international and national legislations concerning biodiversity conservation and protection.

“…The ANOVA result revealed that all samples across parameters are significantly different (p ˂ 0.05) in both wet and dry season. Gijo et al [7] assessed the impact of artisanal crude-oil refineries on the physicochemical features of the sediments of the Nun River, where they showed that the operations similarly leads to increase in total organic carbon and total petroleum hydrocarbon.…”

This study aimed to determine the impact of artisanal refinery operations on the physicochemical and microbiological properties of soil and water in Igia-Ama, Tombia Kingdom, Rivers State, Nigeria. Physicochemical parameters along with concentrations of heavy metals, polyaromatic hydrocarbons (PAHs), total petroleum hydrocarbon (TPH), benzene, toluene, ethylbenzene and xylene (BTEX), and polychlorinated biphenyls (PCB) were determined in soil and water samples using standard methods. Microbial populations were determined using standard plate count. Microbial isolates were identified based on their cultural, morphological and biochemical characteristics. Results show that concentrations of monitored physicochemical parameters differed significantly (p<0.05) between impacted sites and control as well as between dry and wet season. Heavy metals, PAHs, TPH, BTEX and PCB concentrations were higher in the impacted sites than in the control (significant, p<0.05), and also differed significantly between dry and wet season. Microbial counts varied between polluted samples and control as well as between dry and wet season, though not significantly different (p>0.05). Bacterial isolates in polluted soil samples were identified as Enterobacter sp., Bacillus sp., Micrococcus sp., Staphylococcus sp. and Pseudomonas sp. Bacteria in polluted water samples were identified as Staphylococcus sp. and Escherichia coli. Fungi in polluted soil samples were identified as Aspergillus sp., Penicillium sp. Fusarium sp., Rhodotorula sp., Exophiala sp. and Crypotococcus sp. While only Penicillium sp. was isolated in polluted water sample. Artisanal crude oil refinery operations significantly impacted the physicochemical properties of soil and water in the study area but not the microbiological properties. The levels of heavy metals, PAHs, TPH and BTEX in the soil and water suggest the need for remediation of the impacted environment.

“…Gijo et al [27] reported that the activities of makeshift oil refining had adversely impacted on the benthos organisms. The authors reported 30 species (from 15 families) of benthic macro invertebrates during the baseline study, and 18 species (from 10 families) after impartation of the environment by the activities of illegal refinery in Nun River estuary.…”

“…Gijo et al [28] reported that illegal refineries in Nun River estuary of Bayelsa state have led to pollution of the sediment of the water. The authors reported high concentration of pH, total hydrocarbon content and total organic carbon in the range of 5.11 to 6.32, 17.8mg/kg to 1125.9mg/kg and 0.34mg/kg to 51.4mg/kg, respectively.…”

Abstract:Water is an essential resource required for the sustainance of life. Water is utilized in all sector of any nation economy. Surface water is one of the major sources of water utilized by several communities in coastal region of Bayelsa state. Fishing -a source of livelihood for indigenous people of Bayelsa state is carried out in surface water. Surface water is also a route of transportation using engine boat and canoe. Some of the surface water are used for domestic purposes (such as washing, bathing, cooking) and even drinking. Several anthropogenic activities are carried out in the surface water including dredging, makeshift refinery and dumpsite for various classes of wastes (mainly from domestic and sewage). This paper reviews the impacts of anthropogenic activities in surface water resources in Bayelsa state, Nigeria. The study found that pH, temperature, conductivity, total suspended solid, total dissolved solid, total hardness, total alkalinity, turbidity, nitrite, nitrate, phosphate, sulphate, chloride, sodium, potassium, magnesium, calcium, zinc, copper, iron, lead, cadmium, chromium, lead, mercury and total hydrocarbon content are altered due to various anthropogenic activities. Off these, turbidity is significantly affected by all the activities and to lesser extent pH, total alkalinity, dissolved oxygen, nitrite, magnesium, total hydrocarbon content, iron and lead are also affected above permissible level recommended Standard Organization of Nigeria and the World Health Organization. The alteration of water quality parameters could alter the composition and abundance of biodiversity including fisheries and planktons, downstream application of the water and its potability. This study concludes by suggesting that factors leading to alteration in water quality should be checkmated by appropriate regulatory agencies.
