“…In the view of Oghenejoboh et al [28], the factors governing the spread/migration of spilled oil in soil include the amount of oil spilled, physical properties of the spilled oil (density and viscosity), and physical properties of the soil medium itself, particularly its porosity. Although the introduction of PH affects the physical, chemical, and biological properties of soil [7], these factors (i.e., the soil type, quantity, and composition of the spilled hydrocarbon) also determine the level of alteration of the soil properties [27,29].…”

“…PH contamination which is associated with an increase in carbon/nitrogen (C/N) ratio and nitrogen deficiency [32], may also lead to a reduction in plant stem height, stem density, aboveground biomass, and include death of the plant [33][34][35][36][37]. Meanwhile, the response of plants to the presence of PH in soil varies [20,38,39] and is associated with the plant age [40], species of the plant involved, type and concentration of the petroleum, time of exposure to the contaminant [20,29,38] as well as the season [36,41], among other factors.…”

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

2019

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.

“…Major spills of crude oil from oil platforms, pipelines and tankers often occur in the open sea where the released material can be transported far from the source by winds and currents [ 2 , 3 , 4 ]. In many cases, oil reaches coastal areas, where it can adversely impact the terrestrial environment [ 5 , 6 ] and lead to increased erosion in marshes [ 7 ]. In fact, some forms of weathered oil can persist for years [ 8 , 9 ].…”

Experimental L-Band Airborne SAR for Oil Spill Response at Sea and in Coastal Waters

Satellite synthetic aperture radar (SAR) is frequently used during oil spill response efforts to identify oil slick extent, but suffers from the major disadvantages of potential long latency between when a spill occurs and when a satellite can image the site and an inability to continuously track the spill as it develops. We show using data acquired with the Uninhabited Aerial Vehicle SAR (UAVSAR) instrument how a low noise, high resolution, L-band SAR could be used for oil spill response, with specific examples of tracking slick extent, position and weathering; determining zones of relatively thicker or more emulsified oil within a slick; and identifying oil slicks in coastal areas where look-alikes such as calm waters or biogenic slicks can confound the identification of mineral oil spills. From these key points, the essential features of an airborne SAR system for operational oil spill response are described, and further research needed to determine SAR’s capabilities and limitations in quantifying slick thickness is discussed.

“…Because shoreline stability directly influences the adjacent interior marsh status [Knutson, 1987], the widespread and often severe impact of oil on the near-shore marshes in southeastern Louisiana raised concern that oil contamination and the subsequent remediation activities could intensify RANGOONWALA ET AL. MRD shoreline retreat and marsh degradation and loss [Pezeshki and DeLaune, 2015]. Heightening that concern is the common occurrence of intense cyclones that have been observed to increase wave heights up to 2 m in coastal bays, greatly aggravating shoreline erosion [Wilson and Allison, 2008], particularly in the absence of healthy root structure [Knutson, 1987].…”

We evaluate the relative impact of petroleum spill and storm surge on near‐shore wetland loss by quantifying the lateral movement of coastal shores in upper Barataria Bay, Louisiana (USA), between June 2009 and October 2012, a study period that extends from the year prior to the Deepwater Horizon spill to 2.5 years following the spill. We document a distinctly different pattern of shoreline loss in the 2 years following the spill, both from that observed in the year prior to the spill, during which there was no major cyclonic storm, and from change related to Hurricane Isaac, which made landfall in August 2012. Shoreline erosion following oiling was far more spatially extensive and included loss in areas protected from wave‐induced erosion. We conclude that petroleum exposure can substantially increase shoreline recession particularly in areas protected from storm‐induced degradation and disproportionally alters small oil‐exposed barrier islands relative to natural erosion.
