Burial

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

$pst_{bur}=v_b*SA*\frac{pst_{lksed}}{V_{tot}}$ 8:4.2.14

where $pst_{bur}$ is the amount of pesticide removed via burial (mg pst), $v_b$ is the burial velocity (m/day), $SA$ is the surface area of the water body (m$^2$), $pst_{lksed}$ is the amount of pesticide in the sediment (mg pst), and $V_{tot}$ is the volume of the sediment layer (m$^3$).
