According to a study in Ireland, some bottles release up to 16 million microplastics per liter. Each child ingests more than a million each day. Researchers now want to understand the potential consequences of this ingestion rather than unnecessarily alarming the results of this study. Baby plastic bottle health hazard is as follows:
Baby plastic bottle health hazard
Researchers indicate that some bottles can release up to 16 million particles per liter. In fact, the release of microplastics results from the temperature of the water for the preparation of milk. According to the authors, water heated to 95 ° C can release up to 55 million particles per liter! In contrast, in the case of water heated to only 25 ° C, the particle number drops to around 500,000. Based on sales figures for bottles in 48 countries, the researchers estimated that a baby of 12 months ingests an average of 1.5 million microplastics per day. Furthermore, the phenomenon is more important in developed countries since breastfeeding is a less common practice.
Temperature affects the release of particles
As the issue of microplastics grows in importance, a recent study focuses on the particles released from baby bottles. According to a team from Trinity College Dublin (Ireland) who published a study in the journal Nature Food on October 19, 2020, a baby can swallow more than a million microplastics every day! The study leaders tested the best-selling polypropylene baby bottle models on the market. They exposed them to the preparation procedure advised by the World Health Organization (WHO). This consists of sterilizing the bottle and preparing the formula using water at 70 ° C in order to eliminate unwanted bacteria.
The authors of the study indicate that they do not want to alarm parents unnecessarily. Indeed, researchers do not have enough information on the consequences of the phenomenon to make a formal statement. In any case, the extent of microplastic contamination in food is no longer to be proven. In the summer of 2020, WWF published a report claiming that the average person ingests up to five grams of plastic per week, the equivalent of a credit card.
However, unknowns remain regarding health impact. Are there any risks regarding the ingestion itself? What about the chemical risks of additives? Some researchers are going with their hypothesis. For example, the particles could pass through the body very quickly. In addition, concerning polypropylene bottles, these have been particularly highlighted since 2010, when bottles containing bisphenol A were banned.
Plastic baby bottle Alternatives
Researchers at Trinity College Dublin have released several recommendations. The goal? Limit exposure of babies. This involves, for example, rinsing the bottles several times in cold sterilized water, preparing the milk powder in a container other than plastic and pouring the cooled liquid into the bottle. In addition, it is your responsibility to avoid shaking the bottle too much and placing it in the microwave.
