The concentrations of dioxins were compared using isomer-specific analyses of both uncooked and cooked edible parts of the plant. The mean total 2,3,7,8-chlorine substituted PCDD and PCDF concentrations were reduced from 46.53 pg\/g and 0.714 pg\/g to 8.301 pg\/g and 0.210 pg\/g by washing with tap water, and further reduced to 6.054 pg\/g and 0.148 pg\/g by subsequent boiling, respectively. The cooking processes markedly decreased the concentrations of PCDD\/Fs, while having little effect on those of dioxin-like PCBs. The mean total concentration as 2,3,7,8-tetraCDD equivalents (TEQ) was reduced from 0.058 pgTEQ\/g to 0.026 pgTEQ\/g by washing with tap water and further reduced to 0.019 pgTEQ\/g by subsequent boiling. These results suggest that ordinary cooking processes provide a means of reducing the level of dioxins in green leafy vegetables.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-55792","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"\"HORI T,FUKUOKA INST HLTH & ENVIRONM
