English Abstract Emission measurements at the municipal solid waste
incinerator (MSW) AVR at Rozenburg show an average dioxin concentration of
53 ng TEQ/Nm3 (dry, 11% oxygen) in the stack gas. Levels are expressed in
2,3,7,8-TCDD toxicity equivalents (TEQ). The measured level of chlorinated
dioxins and furans in the stack gas is considered to be rather high for this
type of installation in comparison with other MSWs in the Netherlands. The
yearly emission of these compounds is estimated to be 253 g TEQ/year from
this installation, which makes the AVR the quantitatively most important
among the known dioxin sources in the Netherlands. According to dispersion
model calculations this emission contributes considerably to the yearly mean
deposition in the surroundings, viz. on average 23 (11-43) ng TEQ/(m2.year)
over an area of 20x20 km2 and a maximum of 116 (61-233) ng TEQ/(m2.year) at
700 m North-East of the installation. The background deposition is
estimated at a level of 8 ng TEQ/(m2.year). As a result of the AVR dioxin
emissions, high concentrations were found in the "Lickebaert" area.
Concentrations in soil have been found of 27 (18-51) ng TEQ/kg dry soil (5
pastures), which exceed the draft tolerable level for soil in pastures of 10
ng TEQ/kg dry soil. Levels in slaughter products were found between 6.1-
11.2 pg TEQ/g fat and in cow's milk between 2.8-12.6 pg TEQ/g milk fat.
The standard for cow's milk is 6 pg TEQ/g milk fat.
