Based on the results of an inventory of possible dioxin sources other than municipal solid waste (MCW) incinerators, a number of sources not previously measured, are selected for additional measurements. The results of all measurements carried out in the Netherlands, partly supplemented with data from the literature were then elaborated into a total estimate of the dioxin emissions in the Netherlands. In total, the emission to air in 1991 was 484 g I-TEQ. Of that total, the MSW incinerators emit the largest quantity, i.e. 80% of the total. The remainder of the estimated yearly emission is distributed over 16 different process categories. As a result of emission regulating developments it is expected that the dioxin emission in the year 2000 will be descreased to 58 g I-TEQ.
