Questionários com perguntas a respeito de hábitos alimentares, condições sociais e econômicas, e locais de habitação foram aplicados. As mães amamentavam apenas um bebê e as amostras de leite foram coletadas entre 4 e 6 semanas após o parto. Os níveis de PCDD/Fs e dl-PCBs foram de 10,6, 4,77 e 6,96 pg TEQ/g, respectivamente. A compreensão e identificação de fontes de poluição podem ser úteis para as medidas contra a contaminação com dioxinas do leite materno. É importante para as mulheres grávidas ter uma alimentação mais livre possível de contaminantes químicos. Pesquisas complementares devem ser realizadas para avaliar com mais precisão os efeitos desses compostos. A contaminação circunstancial por PCDD/Fs e dl-PCBs em mães que vivem em área industrial no Rio de Janeiro é menor do que geralmente é encontrado nos países industrializados.A study of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and polychlorinated biphenyls (dlPCBs)was conducted in a pooled sample of breast milk from 27 primiparous mothers living in 12 locations in the meso-region industrial area of southern Rio de Janeiro, Brazil, between August 2012 and July 2013. Questionnaires with questions regarding food habits, social and economic conditions and places of dwelling were applied. Milk was collected between four and six weeks after delivery from mothers were breastfeeding only one infant. The toxic equivalency (TEQ) of PCDD/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 applying better counter measures against breast milk dioxin contamination. It is important for pregnant women to have a diet that is as free as possible from chemical contaminants. Further research must be undertaken in the context of epidemiological investigations to more accurately assess the effects of these compounds. The background contamination by PCDD/Fs, and dl-PCBs in mothers living at industrial area in Rio de Janeiro is lower than that generally found in industrialized countries.Un estudio de PCDD/Fs y dl-PCBs se llevó a cabo en una muestra combinada de leche materna de 27 madres primíparas, residentes en 12 barrios que componen la zona industrial sur de Río de Janeiro, Brasil, entre agosto de 2012 y julio 2013. Se aplicaron cuestionarios con preguntas relacionadas con los hábitos alimentarios, condiciones socioeconómicas y lugares de vivienda. Se recogieron muestras de leche entre 4 y 6 semanas después del parto. Los niveles de PCDD/Fs y dl-PCBs fueron 10,6, 4,77 y 6,96 pg TEQ/g, respectivamente. La comprensión y la identificación de las fuentes de contaminación pueden ser útiles para la toma de medidas conzil, our results were lower than those for mothers living in more industrialized countries 2,4,5,6, but comparable to mothers in the city of Rio de Janeiro 10. A child who eats human milk is at the apex of the food chain and thus can receive a higher burden of contaminants eliminated by this pathway, especially those capable of undergoing the phenomenon of biomagnification 4,9. Children are particularly vulnerable to chemical agents present in the environment due to their physiological characteristics. Thus, dioxins, furans and polychlorinated biphenyls in air, water, soil, and food are more likely to be absorbed by children than for adults. Human milk is an important vehicle for elimination of xenobiotics from the tra la contaminación por dioxinas en leche materna. Es importante que las mujeres embarazadas tengan un suministro lo más libre posible de contaminantes químicos. Deben llevarse a cabo más investigaciones para evaluar con mayor precisión los efectos de estos compuestos. La contaminación circunstancial por PCDD/Fs y dl-PCBs en madres que viven en el área industrial de Río de Janeiro es inferior a la que generalmente se encuentra en los países industrializados.Fundação Oswaldo Cruz.
