Breast milk is the natural source of nutrition for infants, but while it supports their health, it can also be a potential source of toxic inorganic particulate matter, and this applies to both breast milk and industrially produced milk. The aim of the present study was to evaluate the presence of nanoparticles in both breast milk and formula milk samples. We collected and analyzed, via a new electron scanning microscopic procedure, 19 samples of breast milk from Italian women and 19 formula milk samples produced by different companies. Organic-inorganic agglomerates were detected in 58% of formula and in 63% of breast milk samples, respectively. In addition, a significantly ( < 0.05) greater size of nanoparticles was observed in formula milk samples. The results, showing the presence of inorganic nanosized particles in breast and artificial milk, may lead to future studies aimed at investigating possible nanosized contamination of milk and identifying early prevention strategies for women and animals involved in the food chain.
母乳是婴儿的天然营养来源，但它在支持婴儿健康的同时，也可能是有毒无机颗粒物的潜在来源，这一点对母乳和工业生产的牛奶都适用。本研究的目的是评估母乳和配方奶样本中纳米颗粒的存在情况。我们通过一种新的电子扫描显微镜程序，收集并分析了19份意大利女性的母乳样本和19份不同公司生产的配方奶样本。分别在58%的配方奶样本和63%的母乳样本中检测到有机-无机团聚物。此外，在配方奶样本中观察到纳米颗粒的尺寸明显更大（<0.05）。这些结果表明母乳和人工奶中存在无机纳米颗粒，可能会促使未来开展研究，旨在调查牛奶可能存在的纳米污染，并为食物链中的女性和动物确定早期预防策略。
