Effects of oil contamination on plant growth and development: a review

Environ Sci Pollut Res Int. 2022 Jun;29(29):43501-43515. doi: 10.1007/s11356-022-19939-9. Epub 2022 Apr 7.

Abstract

Oil spills generate several environmental impacts and have become more common with the increase in petroleum extraction, refining, transportation, and trade. In soil, oil contamination increases water and nutrient availability and compaction, directly affecting plant growth and development. Different aspects of phytotoxicity can be observed and will vary according to the characteristics of soil and plants. Oil-contaminated soil also results in negative effects on biomass and changes in leaves and roots. Investigating the effects of oil contamination on plant growth and development can aid in the conservation of plant species and in the development of techniques such as bioremediation and biomonitoring. Thus, this review aims to discuss the main effects of oil contamination on plants, such as environmental stress and morphological, physiological, and anatomical changes, and the strategies developed by plants to survive contamination, as well as to identify plants with phytoremediation potential that can assist in removing oil from the environment.

Keywords: Oil pollution; Phytoremediation; Phytotoxicity; Plant ecophysiology.
