English Abstract Emission measurements at the sinter plant of Hoogovens
at IJmuiden show an average dioxin concentration in the stack gas of circa
2,8 ng TEQ/Nm3 (dry). The yearly emission of dioxins from this installation
is estimated at 24 g TEQ. According to dispersion model calculations this
emission results in a yearly mean deposition of circa 1,2 ng TEQ/(m2*year)
over an area of 20x20 km2 with a maximum of 6,2 ng TEQ/(m2*year) at circa
700 m North-East of the installation. There are no cows grazing in the
vicinity of the deposition maximum. Dioxin levels in cow's milk from dairy
farms 6-10 km North-East of Hoogovens ranged from 0.8 to 1.4 pg TEQ/g milk
fat (n=4). The dioxin level in soil from a pasture 6 km North-East from
Hoogovens was 2,6 ng TEQ/kg dry soil. The deposition of dioxins, the dioxin
levels in cow's milk and in soil in the vicinity of Hoogovens are not
enhanced with respect to the average background levels in the
Netherlands.
