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

5 textile finishing 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--dioxins 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 concentration 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 depositions contain higher PCDD/F-concentrations up to 1,806.1 ng I-TE/kg, PBDD/F-concentrations up to 1,572.6 ng/kg and PBCDD/F-concentrations up to 40,801.4 ng/kg.
