Almost half (45%) of the petroleum entering the marine environment is from natural seeps rather than anthropogenic sources. At seeps, oil and gas bubble out of cracks in the seabed creating special environments in which new organisms grow. These organisms survive through chemosynthesis rather than ...

In order to remediate soil contaminated with petroleum hydrocarbons, this study evaluated the potential of iron oxide nanoparticles (FeONPs), synthesized using an aqueous leaf extract of Diodella sarmentosa (sw). The FeONPs were characterized using a high resolution transmission electron microscope (TEM...
