“…The adverse effects of crude oil/petroleum hydrocarbons on soil physico-chemicals and biological properties have already been reported 1,11 . The crude oil contamination clogged the soil pore spaces, reduces soil porosity, aeration, water infiltration and increases the bulk densities which ultimately reduces water holding capacities and hampers the nutrients availability for plants 14,15 . This in turn also hampers the survival of plants in the oil polluted habitats.…”

“…The present findings regarding soil physico-chemical and biological parameters clearly indicate the adverse effects of crude oil on soil system. The crude oil contamination clogged the soil pore spaces, holds the soil particles together and reduces soil porosity, aeration, water infiltration and increases the bulk densities which ultimately reduce water holding capacity and destroys the soil textures 15 . Besides, lower soil porosity and water holding capacity are also associated with reduction in microbial population, poor mineralization and nutrients availabilities in the soil 14 .…”

Hydrocarbons or crude oil contamination of soil is still a burning problem around the globe. The herbs competent that are to survive in hydrocarbons contaminated habitats have some adaptive advantages to cope up with the adverse situations prevailing in that environment. In the present study, the adaptive response of Cyperus brevifolius in the heavily polluted soil with crude oil has been investigated in terms of survivability, changes in productivity, antioxidants, phytochemicals and functional group pro files of the plant species. Besides, changes in enzymes, beneficial bacterial population and physico-chemical conditions of contaminated soil were also studied during 60 days of experimental trials. The results showed significant enhancement in activities of soil dehydrogenase, urease, alkaline phosphatase, catalase, and amylase whereas reduction in cellulase, polyphenol oxidase and peroxidase activities. There was a significant increase in nitrogen fixing, phosphate and potassium solubilizing bacterial population, improvement in physico-chemical conditions and a decrease in total oil and grease (TOG) levels. Besides there was significant variations in the productivity parameters and antioxidant profiles of Cyperus brevifolius in hydrocarbons stress condition suggesting enzymatic defense of the herb. The fourier-transform infrared (FT-IR) analysis indicated uptake and metabolism of some hydrocarbon components by the experimental plant from the hydrocarbons polluted soil.

“…Crude oil pollution, arising from exploration and processing operations, is a common environmental challenge [1]. This introduction of crude oil (via large or small spills) into the environment could arise from technical errors, deliberate human acts as well as transportation and storage faults [2][3][4][5][6]. Schmidt-Etkin [7] noted that although large spills sometimes occur with serious environmental and socioeconomic damage, small spills are more common.…”

Understanding the Impacts of Crude Oil and its Induced Abiotic Stresses on Agrifood Production: A Review

2019

View full text Add to dashboard Cite

In many parts of the world, the agricultural sector is faced with a number of challenges including those arising from abiotic environmental stresses which are the key factors responsible for most reductions in agrifood production. Crude oil contamination, an abiotic stress factor and a common environmental contaminant, at toxic levels has negative impacts on plants. Although various attempts have been made to demonstrate the impact of abiotic stresses on crops, the underlying factors responsible for the effects of crude oil and its induced abiotic stresses on the composition of the stressed plants are poorly understood. Hence, this review provides an in-depth examination of the: (1) effect of petroleum hydrocarbons on plants; (2) impact of abiotic environmental stresses on crop quality; (3) mechanistic link between crude oil stress and its induced abiotic stresses; as well as (4) mode of action/plant response mechanism to these induced stresses. The paper clearly reveals the implications of crude oil-induced abiotic stresses arising from the soil-root-plant route and from direct application on plant leaves.

“…34 There is nowhere that this is more accurate than in the Niger Delta region, as the actions of multinational oil companies have contributed to environmental degradation and untold hardship in the affected communities, especially for women. 35 Some of these women tend to diversity their livelihood activities by engaging in trading business, especially when their husbands or partners have left in search of alternative income following the pollution of their farmlands and fishing grounds. 36 For others, alternative source of livelihood includes 'taking advantage of the cash inducement of oil workers and others in the oil economy' 37 by engaging in prostitution.…”

The effects of oil pollution on the marine environment in the Gulf of Guinea—the Bonga Oil Field example

Fish makes a significant contribution to the food security of millions of people in the Gulf of Guinea, accounting for up to 80 per cent of the animal protein, and sometimes is the only source of thereof, consumed in coastal communities across the region, including those in the Niger Delta area of Nigeria. However, such contribution is increasingly undermined by unsustainable practices that are harmful to the marine environment such as pollution, illegal, unreported and unregulated (IUU) fishing, and by climate change. This paper focuses on the role that pollution from oil spillages plays in damaging the marine environment, thereby exacerbating food insecurity in the region. Using the Bonga Oil Field spillage example, the paper exposes, from a policy perspective, the manner in which the shortcomings of existing environmental regulations and their implementation in Nigeria weaken efforts for a sustainable marine environment and, by extension, threatens the food security of coastal communities.
