Perfluorinated carboxylic acids in human breast milk from Spain and estimation of infant's daily intake

Abstract.The aim of the present study was to determine the effect of vitamin C supply in the diet of lactating women on vitamin C concentrations in human milk (n = 97) sampled at different stages of lactation. Vitamin C levels were measured by liquid chromatography. Dietary intake of vitamin C was determined based on 3-day food dairies kept by breastfeeding mothers. Maternal dietary intakes of vitamin C from natural sources on lactation day 90 (n = 18) were significantly higher than on lactation days 15 (n = 42) and 30 (n = 37). The number of women taking vitamin C supplements decreased in successive stages of lactation. The average daily intake of vitamin C was estimated at 119 mg, but nearly 20% of mothers consumed less than 50 mg of vitamin C per day. No significant correlations were observed between lactation stage and vitamin C levels in breast milk (r = 0.110, p = 0.064). The average vitamin C concentrations in human breast milk were determined at 50.9 mg / L, and were not higher than 80.6 mg / L regardless of lactation stage and maternal intake of vitamin C. Vitamin C excretion into breast milk is regulated to prevent exceeding saturation level. The vitamin C concentration in milk was positive correlated with maternal intake of vitamin C from food, in the case of non-supplemented diet (r = 0.402, p = 0.041). Our results suggest that vitamin C occurring in food is much better absorbed and passes into breast milk than vitamin C from supplements.

The Past

Widespread contamination of human breast milk with chlorinated hydrocarbon insecticides has been repeatedly documented in population surveys in the United States and Canada over the past two decades. Unfortunately, it was not until the most recently published assessments that a strong effort has been made to apply proper biostatistical sampling methodologies to such surveys. This deficiency, along with frequent omission of information on variables known to affect the levels of such contaminants in breast milk, makes precise historical comparisons difficult. Given these uncertainties, it appears that organochlorine insecticide residues in human breast milk have not noticeably changed over the past two decades in the United States despite the regulatory restriction placed on several of these substances, such as DDT, since 1970. The surveys have revealed that total DDT levels continue to approach and exceed the Acceptable Daily Intake (ADI) level recommended by WHO. Perhaps of greatest concern is the ubiquitous contamination by polychlorinated biphenyls (PCBs) of breast milk, with levels of the upper 30% of the population being within a factor of 10 of those levels producing adverse health effects in humans and monkeys. The carcinogenic risk assessment for consumption of PCB-contaminated breast milk is also discussed.

AbstractBreast milk is often used as an environmental bioindicator since it serves as an important medium to accumulate organochlorine pesticides. The main aim of this study is to determine the level of organochlorine pesticides in human breast milk collected from three districts of southwestern Ethiopia (Asendabo, Deneba, and Serbo) at three times points baselines (1st month), midline ( six months), and end line (12 months) and risk of infants’ exposure. A longitudinal study was conducted to assess pesticide residues in human breast milk samples and evaluate the risk-exposure of infants to these pesticides from consumption of mother’s milk in Ethiopia. Breast milk samples were collected from 168 mothers at three time points and pesticides were extracted using the quick, easy, cheap, effective, rugged, and safe (QuEChERS) method. The level of pesticide residues in human milk samples and exposure of infants to the pesticides was evaluated by calculating the estimated daily intake and compared with the provisional tolerable daily intake of the pesticides under study. The results indicated that, from the eight organochlorine pesticides analyzed in 447 breast milk samples at three sampling times, DDT and its metabolites were detected. p,p′-DDE and p,p′-DDT were detected in all (100%) of the breast milk samples while, p,p-DDD, and o,p-DDT were detected in 53.9%, and 42.7%, respectively. The mean concentration of total DDT at three time points(baseline, midline and endline) were 2.25, 1.68 and 1.32 µg/g milk fat, respectively. The mean concentration of total DDT from the three districts was 1.85 µg/g milk fat which is above the maximum residue limit (MRL = 0.02 µg/g milk fat set by FAO/WHO). The mean ratio of DDT/DDE for the three areas was calculated less than five (< 5) indicates historical DDT use in the study area. The estimated daily intake of infants at the first month of breastfeeding was 11.24 µg/kg-BW/day, above the provisional tolerable daily intake (PTDI) for total DDT set by FAO/WHO, which is 10 µg/kg body weight. An intake of OCPs is a big concern for infants' health in Ethiopia and countries with a similar condition, particularly at the first month of lactation. Strict regulations of the health-threatening pesticide by the regulatory body (Environment, Forest and Climate Change Commission) at the country and regional levels is advocated.

Activation Pathway

Neonatal necrotizing enterocolitis (NEC), which is a disease with a poor prognosis, is considered to be caused by the coincidence of intestinal ischemia-reperfusion injury and systemic inflammation due to the colonization of pathogenic bacteria. Interleukin (IL)-8, a proinflammatory cytokine, plays an important role in the pathophysiology of NEC. It was recently reported that IL-1β activates the IL-8 gene by regulating the transcriptional nuclear factor κB (NF-κB) signaling pathways in intestinal cells. The protective role of maternal milk in NEC pathogenesis has been reported in both human and animal studies. In this study, we show that human breast milk dramatically suppressed the IL-1β-induced activation of the IL-8 gene promoter by inhibiting the activation pathway of NF-κB. Moreover, we also show that human breast milk induced the production of IκBα. These results suggest that human breast milk could be protective and therapeutic in neonates with NEC by inhibiting the activation pathway of NF-κB.
