Microplastics are released from infant feeding bottles: Millions of infants could be vulnerable to high levels of microplastics released throughout formula preparation from feeding bottles.
That’s admitted from new research by AMBER, the Science Foundation Ireland Research Centre for Advanced Materials and Bioengineering Research, TrinityHaus and the Schools of Engineering and Chemistry at Trinity College Dublin, which discovered a strong connection between heat and microplastics release from infant-feeding bottles.
The analysis suggests under standardised rules of conduct, after sterilisation & exposure to water at 70⁰C, the polypropylene infant-feeding bottles (PP-IFBs) discharged up to 16.2 million polypropylene microplastics (PP-MP) per litre.
The scientific unit, which developed a protocol to quantify the PP-MPs discharged from ten typical infant-feeding bottles that make up 68.8% of the global infant-feeding bottle market, and estimated the vulnerability of 12-month-old infants to MPs in 48 countries & regions.
That was done by using MP release rates via PP-IFBs, the infant daily milk-intake amount, the market share of individual PP-IFB, & breastfeeding rates.
The team discovered the infants per capita overall average daily consumption of polypropylene microplastics was 1,580,000 particles.
Europe, North America and Oceania were also discovered to possess the highest levels of possible exposure comparable to 2,100,000, 2,280,000, & 2,610,000 particles per day, mutually.
John Boland, Professor at AMBER, CRANN & Trinity’s School of Chemistry, declared: “The last thing we want is to unduly alarm parents, particularly when we don’t have sufficient information on the potential consequences of microplastics on infant health.
“We are calling on policymakers, however, to reassess the current guidelines for formula preparation when using plastic infant feeding bottles.”
Liwen Xiao, Professor at TrinityHaus & Trinity’s School of Engineering, explained: “Our study indicates that daily use of plastic products is an important source of microplastic release, meaning that the routes of exposure are much closer to us than previously thought.”
