ClearFeasibility of Raman and FTIR spectroscopy for direct microplastic search in the human milk samples: Comparative qualitative study
Researchers tested whether infrared and Raman spectroscopy could detect microplastics directly in human breast milk without harsh chemical processing that might damage the samples. They found these methods can serve as a useful screening tool for common plastics like polyethylene and polystyrene in milk, which matters because breast milk is a direct route of microplastic exposure for infants.

Detection and quantification of microplastics in milk from Chandigarh, India: a pilot study highlighting SFEC-based spectral validation
Scientists found tiny plastic particles in all milk samples they tested from India, including both store-bought and farm-fresh milk. The plastic pieces came from common materials like water bottles and food packaging, with concentrations ranging from about 100 to 270 particles per liter of milk. While this is just a small pilot study, it suggests people may be consuming microplastics through milk, though more research is needed to understand any potential health risks.

Detection and quantification of microplastics in milk from Chandigarh, India: a pilot study highlighting SFEC-based spectral validation
Scientists found tiny plastic particles in all milk samples they tested from India, including both store-bought and farm-fresh milk. The plastic pieces were very small (called "microplastics") and came from common materials like water bottles and food packaging. While this is the first clear proof that microplastics are getting into our milk supply, we still need bigger studies to understand what health risks this might pose to people who drink milk regularly.

Scientists examined placentas from 50 women after delivery and found microplastics in 62% of them, with seven different plastic types identified including Teflon (PTFE), polystyrene, and ABS. While the particles did not appear to affect birth weight, length, or gestational age in this study, their widespread presence in placental tissue confirms that plastic pollution reaches developing babies before birth. More research is needed to understand potential long-term effects.
