Mirex (MW = 540) is a fully chlorinated organic
pesticide that was manufactured to control
fire ants. Due to its structure, mirex is very
unreactive; thus, it persists in the environment.
Kuwait Bay water samples have had mirex measured
as high as 0.002 µg/L and Zubaidi fish samples with 0.002 µg/g.
