TEQs of PCDDs/Fs, and dl-PCBs were 10.6, 4.77, 6.96 TEQ pg/g, respectively. The understanding and identification of pollution sources may be helpful for taking better counter measures against breast milk dioxin contamination. It’s important for pregnant women to have a diet free as possible of contaminants chemical. Further research must be undertaken in the context of epidemiological investigations to more accurately assess the effects of these compounds.</span><!--[if gte mso 9]><xml> <w:WordDocument>
