Polyhalogenated dibenzo-p-dioxins and dibenzofurans in the exhaust air during textile processings

5 textile fmishing processes were investigated for polychlorinated dibenzo-p-dioxins/furans (PCDD/F), polybrominated dibenzo-p-dioxins/furans (PBDD/F) and mixed polychlorinated-brominated dibenzo-p-dioxins/furans (PBCDD/F). For the purpose of these investigations the complete balance — dioxin input from the raw textiles, output over the finished textiles and output through the air path — was done. In the exhaust air only small PXDD/F concentrations were detected. The textiles contain before and after the process nearly the same PCDD/F-concentrations. The concentrations of PBCDD/F arises after the process. Only the chimney depostions contain higher PCDD/F-concentrations up to 1 806.1 ng I-TE/kg, PBDD/F-concentrations up to 1572.6 ng/kg and PBCDD/F-concentrations up to 40 801.4 ng/kg.
