(Eisenreich et al., 1981). In particular, the strong retention of HCB to sediment
particulates in the water allowed much of the historical burden to become
immobilized in bottom sediments, with a concomitant reduction in the levels of
HCB found in the surface waters.
More evidence for HCB’s persistence in soil was observed in a laboratory study.
Arial application of HCB in a greenhouse with simulated pasture conditions
showed that HCB volatilized fairly rapidly from plant and soil surfaces (Beall,
1976). Only 3.4% of HCB remained in the top 2 cm of soil 19 months after
spraying. Residues on the grass grown in the soil volatilized considerably faster,
with only 1.5% remaining on the plants after two weeks, and
