Fos is the site of a major port development operated by the Autonomous Port of Marseille. The facilities include container handling terminals and a gas (methane) terminal. The waterside location of the industrial zone is attractive to heavy industry including steel. The steel group
ArcelorMittal has its
Sollac Méditerranée plant here (merged into ArcelorMittal in 2006). The presence of the steel, chemistry and oil industries means that pollution levels are high. ==Sports==
