Air sampling throughout an oil spill is often executed for overall health and security causes as a result of existence of volatile constituents evaporating from the spilled oil, and that is a specific issue in the situation of gasoline spills.
As presently mentioned earlier mentioned, Each individual station really should gather samples day by day.
