Burial

Pesticide in the sediment layer may be lost by burial. The amount of pesticide that is removed from the sediment via burial is:

$pst_{bur}=\frac{v_b}{D_{sed}}*pst_{rchsed}$ 7:4.2.13

where $pst_{bur}$ is the amount of pesticide removed via burial (mg pst), $v_b$ is the burial velocity (m/day), $D_{sed}$ is the depth of the active sediment layer (m), and $pst_{rchsed}$ is the amount of pesticide in the sediment (mg pst).
