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.

Health risk assessment of selected heavy metals in gari (cassava flake) sold in some major markets in Yenagoa metropolis, Nigeria Submit Manuscript | http://medcraveonline.com MOJ AbstractGari (cassava flake) is a major staple food in Nigeria. It's also a major source of energy food to several families. This study evaluated the health risk assessment of selected heavy metals in gari sold in some major markets in Yenagoa metropolis, Nigeria. Triplicate gari sample were obtained from four different markets in Yenagoa metropolis, Nigeria. The samples were ashed, digested and analyzed using atomic adsorption spectrophotometer. Health risk assessment was carried out using target hazard quotient, health risk index and daily intake index. Result revealed that the heavy metals concentration ranged from 1.32-3.81 mg/kg (manganese), 2.21-5.66 mg/kg (zinc), 1.00-3.72 mg/kg (copper) and 11.16-38.75 mg/kg (iron). There was significant difference (P<0.05) in each of the heavy metals among the various locations. The target hazard quotient and health risk index values were <1. This indicates no potential health risk of the studied heavy metals in the gari among the population under study.Citation: Kigigha LT, Nyenke P, Izah SC.

“…In addition the soil environment is a major recipient of waste streams emanating from food processing including oil palm, 71 cassava processing. 35,[67][68][69]72 These wastes are rarely treated in Nigeria before disposal. After heavy precipitation they could be washed into the nearby surface water (major sink of pollutants) thereby causing an alteration in water and sediment quality depending on the constituents and concentration of toxicants/ hazardous substances found in the water.…”

Some biodiversity of global importance are found in the Niger Delta region of Nigeria. The biodiversity resources of the Niger Delta comprises of several species of mammals, reptiles, amphibians, avian fauna, microorganisms, fisheries (animals), and mosses, liverworts, pteridophytes, gymnosperms, chlamydosperms, monocotyledons, dicotyledons etc (plants). The region is hotspots of several endemic species. In recent times, the biodiversity distribution with regard to abundance and diversity appears to be on the decline trend. Hence, this study assessed the factors leading to decline of biodiversity resources in the Niger Delta. The study found that excessive exploitation, urbanization/industrialization, deforestation/habitat destruction, bush burning, soil erosion and pollution, climate change are the leading cause of loss of biodiversity. The loss of biodiversity affects its roles including source of medicinal plants, shelters, habitats, raw materials for several art and construction works (plants), nutrient mineralization through biogeochemical cycles, loss of animal protein and species of global importance. The paper concludes by suggesting full implementation and enforcement of several environmental conventions, laws and legislations geared towards protection of biodiversity at both international and national level of which Nigeria is part of. Furthermore, outlining biodiversity conservation strategies in curriculum of school is another potential option for conserving biodiversity.
