The accidental spill of some 10,000 barrels of Buzios crude oil during the unloading operations of a tanker reached approximately 11,000 ha at sea and 120 ha on land, along a coastal marine ecosystem.
Several episodes of crude oil contamination in the oil extraction areas of the Middle East have led to the development of one of the largest Excavation, Transportation and Remediation projects of its soils worldwide.
Identification of 3600 m2 of soils affected by light hydrocarbons from aviation jet storage in plots with different intended uses.
Photocatalysis is a chemical reaction that removes common atmospheric pollutants such as VOCs, NOx and SOx through an oxidation process activated by solar energy.
The most commonly used photocatalyst is titanium dioxide (TiO2).
