“…No adverse or toxic effect was reported with L. minuta for the removal of phenol ranging from 25 to 250 mg/L 31 . Even in studies where macrophytes performance was below expectations 32,33 , the results were unconnected with the inhibition or incapacitation of the species.…”

“…The increasing trend in the potentials of selected macrophytes to remove a significant level of organic compounds from contaminated media is vital for the development of pilot wetlands for the treatment of wastewater from industrial activities. Despite the results, studies with water lettuce, P. stratiotes and the giant duckweed Spirodela polyrrhiza were unsuccessful 23,32 while black rush performs poorly (15%) in the removal of petroleum hydrocarbons from contaminated sediments 33 . Although macrophytes can remediate pollutants in water, several uncertainties such as plant handling, locality, contaminant behaviour, and other environmental factors could affect the remediation potentials of plants.…”

The potentials of the invasive duckweed species, Lemna paucicostata to remove pollutants from aquatic environment was tested in a constructed wetlands as an ecological based system for the phytoremediation of petroleum hydrocarbons in crude oil-contaminated waters within 120 days. Total petroleum hydrocarbons in wetlands and tissues of duckweed were analyzed using gas chromatography with flame ionization detector following established methods while the experimental data were subjected to the first-order kinetic rate model to understand the remediation rate of duckweed in wetlands. L. paucicostata effected a significant (F = 253.405, P < 0.05) removal of hydrocarbons from wetlands reaching 97.91% after 120 days. Assessment on the transport and fate of hydrocarbons in duckweed indicated that L. paucicostata bioaccumulated less than 1% and significantly biodegraded 97.74% of hydrocarbons in wetlands at the end of the study. The experimental data reasonably fitted (r 2 = 0.938) into the first-order kinetic rate model. From the result of the study, it is reasonable to infer that L. paucicostata is an effective aquatic macrophyte for the removal of petroleum hydrocarbons in moderately polluted waters. The expansion of the chemical industry after the dawn of the industrial age has significantly increased the levels of contaminants entering the natural and human environment. Among the many chemical industries, the petrochemical industry is a major player in the global energy landscape despite significant investment and interest in alternative energy. Today, petroleum remains a significant energy demand in modern society. In spite of all the necessary safety and precautionary approach in the petroleum industry, oil spill is an inevitable occurrence in the production, transport, processing and consumption of crude oil 1,2. The continuous advancement in offshore exploration has increased the level of exposure of hydrocarbons into aquatic environment, particularly freshwater, creating a cascade of negative impact on organisms relying on freshwater resources 3,4. Oil spills in water leads to extensive damage of water resources including sensitive habitats. It suffocates aquatic life and renders water unfit for communal and domestic use 5. Over the years, various technological approach has been developed for the treatment of oil spill in marine and coastal waters, as well as rivers, streams, wetlands, swamps and lakes 6-9. Chemical methods involving the application of dispersants and in situ burning have unintended consequences despite the success recorded with such application 8,10. The unintended effects with the application of chemicals for oil spill cleanup have given opportunities to the development of biological and nature-based solutions over the past three decades for the remediation of contaminants in aquatic environment 7,11. The usefulness of plants in the biological remediation of contaminants has been expanding over the years. Several species of plants with the potentials to remove a wide range of contaminants fro...

“…There are some phyto-remediation studies on floating plants such as water lettuce (Pistia stratiotes) and duckweed (Spirodela polyrrhia) for removing crude oils of oil-polluted water bodies. However, their performance was not promising (Agbogidi and Bamidele, 2009;Akapo et al, 2011). In general, there are few studies to identify the ability of aquatic species for crude oil phyto-remediation.…”

The discovery of crude oil in commercial quantities in the Niger Delta was echoes of riches and wealth to the region and the country, Nigeria but the Niger Delta environment and aquatic ecosystems suffers great anthropogenic pollutions to its biodiversity: birds, animals, plants and crops; fishes and wildlife. This article has reviewed the effects of crude oil spill on the aquatic life (fish) in the Niger Delta, examining cases of oil spill incidences, impacts of oil exploration and exploitation on the environment, management of oil spill on living aquatic resources; biomagnification and threat to biodiversity and food security. It also examined the extent of crude oil removal techniques, and finally proffer possible mitigations and compensations for oil spills incidences in the Niger Delta. We are left with a great question: can gas flaring and illegal refineries be stopped, in the Niger Delta? The Niger Delta waters and the aquatic biodiversity should be protected; the government and multi-national oil companies should launch a clean-up programme on the affected areas/the region, and the management of spills (both of catastrophic and local dimensions) will play a leading role by enacting and enforcing stringent environmental laws that will protect the oil producing communities/areas. Government should be able to identify natural resources (such as wetlands and coastal zones) in Nigeria and monetary investment in environmental protection of vulnerable areas should be seriously looked into.

Changes in crude oil production and distribution have increased the incidence of oil spills throughout the world. Oil spills often cause destructive effects on aquatic and land ecosystems. The oil spill cleanup and recovery techniques are challenging and usually involve complex mechanical, chemical, and biological methods. Usually, mechanical removal of free oil is utilized as an effective strategy for cleanup in aquatic and terrestrial environments; however, they are expensive and need specialist personnel and equipment. The other commonly used method is the application of chemical materials such as dispersants, cleaners, demulsifiers, biosurfactants, and soil oxidizers. Nevertheless, these reagents can have potential harmful environmental impacts, which may limit their application. As an alternative, bioremediation can offer reduced environment risk; however, the limitations of microbial activity in the soil can make this option unsuitable. One area of bioremediation is phytoremediation, which offers potential for restoring large areas of contaminated ground. Plants are able to remove pollutants through processes such as biodegradation, phytovolatilization, accumulation, and metabolic transformation. This review presents the fate of crude oil spills in aquatic and land ecosystems and their environmental effects. Furthermore, the paper focuses on crude oil phytoremediation and its applications in polluted ecosystems.
