Growth of seashore paspalum, (<i>Paspalum vaginatum L</i>) in soil contaminated with crude petroleum oil

Abstract

ABSTRACT:The effect of crude oil contaminated soil on the growth of seashore Paspalum ( Paspalum vaginatum .) seedlings was investigated. Plants were grown in soil containing different concentrations: 0%, 0.5%, 1.0%, 2.0% and 3% (w/w) of Abura crude petroleum oil. Growth parameter such as shoot number, shoot length, leaf area and biomass accumulation were evaluated. The results showed that crude oil imposed physiological stress in the seedlings. There was a dose response decline in all the growth attributes examined. There was also a significant difference in plant growth with respect to time of crude oil application. At the highest applied concentration(3 % [w/w]), plants grown in soil previously contaminated with petroleum oil showed about 50 % reduction in biomass accumulation when compared with the uncontaminated control whereas established plants post -treated with crude petroleum oil showed a 30% reduction. There was no mortality at any of the crude oil concentrations to which to plant was exposed. The experiment demonstrated the potential of using Paspalum vaginatum for phytoremediation. @ JASEM

Bacteriological and Physicochemical Properties of Petroleum-Contaminated Soil Collected from a Mechanic Site in Abuja, North-Central Nigeria

“…The inadvertent release of petrochemical agents directly to the soil triggers a chain of events which negatively impacts on biotic and abiotic elements within the environment [25]. Crude oil and its derivatives are composed of aliphatic, oleic, naphthenic and aromatic hydrocarbons, which modify physical and chemical properties of soil and its structure [26].…”

“…Industrialization and global expansion has in recent times witnessed the increase sales of petroleum products that serve the use of automotive devices around the world. Although these products serve the needs of mankind, their disposal presents a unique challenge to the environment for which growing concerns of their effect on human health, damages terrestrial and aquatic life forms, destruction of different ecosystems, depletion of soil fertility, etc has sparked worldwide protests [1][2][3][4][5][6][7]. Avenues by which petroleum products sip or enter the environment is not limited to pipeline leakage or vandalism and tanker accidents spills, inappropriate handling of spent lubrication oils (engine oil) particularly in developing countries represents the most common avenue in developing countries like Nigeria [8][9].…”

Phytotoxic analysis of the impact of transmission oil contaminated soil on germination and growth of oat (<i>Avena sativa</i>) seedlings under different soil moisture conditions

“…Soil phytotoxicity test was carried out at regular intervals by bio-testing the Oat (Avena sativa) seedlings (Bamidele, 2011;Jain, 2011;. The research was performed in the microbiology laboratory of the Russian State Agrarian University-MTAA…”

“…In contrast a low level of petroleum hydrocarbon has a positive impact on plant growth and development, as a result of the mineralization of organic compounds by microorganisms, availability of nutrients, moisture, air etc. (Ekundayo, 2001;Ananieva, 2003;Bamidele, 2011;Jain, 2011;Athar, 2016).…”

“…The contamination of soils by petroleum hydrocarbon severely hinders plant growth and development, due to alteration of the physical and chemical properties of the soil, as well as the disruption of soil microbial activities (Ekundayo, 2001;Bamidele, 2011;Jain, 2011;.…”
