摘要: Abstract Commercial textile products containing 2,4,4′-trichloro-2′-hydroxydiphenyl ether (Irgasan DP3000 as an antimicrobial agent gave dichlorodibenzo- p -dioxin(s) (di-CDD) upon combustion. The extent of conversion Irgasan DP300 into di-CDD(s) reached 19–43% at 600°C. Upon bleaching the with sodium hypochlorite, was chlorinated to 2′-3,4,4′-tetrachloro-2-hydroxydiphenyl ether, 2′,4,4′,5-tetrachloro-2-hydroxydiphenyl and 2′-3,4,4′-5-pentachloro-2-hydroxydiphenyl etherl. These derivatives were converted trichlorodibenzo- -dioxins tetrachlorodibenzo- -dioxin combustion, which are more toxic than di-CDD(s). results suggest that incineration result in environmental pollution by PCDDs.
