What is the half-life time of HCB (hexachlorobenzene) in grassland soils with about 5% humus?

It rises the question in Austria how such grassland soil can be decontaminated and can be used again for fodder production, pastures or forage crops.

I have no data on HCB in grass. In my studies with different poultry types kinetics of HCB were similar to those of DDT and Dieldrin (see attachment). So if there are data on those two, you might expect or hope for similar ones for HCB.
