Bisphenol A in baby bottles:
Bisphenol A, an organic compound with two phenol functional group, abbreviated as BPA. It is a di-functional building block for many essential plastics and plastic additives. Its hazardous nature towards Human was estimated in the year 1930s, and therefore some shopkeepers have stopped keeping products which contains Bisphenol A. However the concern about the use of bisphenol A in several product was always and regularly published in the news paper and other news sources. Recent report gathered from the FDA raised further concerns regarding the exposure of Bisphenol A on fetuses, infants, and young children.
Use of Bisphenol A:
Bisphenol A is generally used in the production of common products such as baby and water bottles, sports equipment, medical devices, dental devices, dental fillings and sealants, eyeglass lenses, CDs and DVDs, and household electronics. It is also used in the synthesis of polysulfones and polyether ketones, as an antioxidant in some plasticizers, and as a polymerization inhibitor in PVC.
Bisphenol A is an endocrine effector that can mimic the body’s own hormones and can lead to health damaging effect. Its early development seems to be the greatest sensitivity to its effects. Looking at the consequences of Bisphenol A, the regulatory bodies have determine the safety levels specially for Humans, but those safety levels doesn’t meet the general set criterion and are under review as a result of new scientific studies. A year back, The Endocrine Society had also released a scientific statement stating concern over current human exposure to Bisphenol A.
It is a common practice that babies in India are fed milk or water from plastic bottles that contain highest estimated levels of Bisphenol A (BPA). Presence of Bisphenol A in infants food can put them at risk. It is also hazardous to fetuses if any pregnant mothers are exposed to it.
Bisphenol A as per the Swiss Study:
As per the Swiss study, the most potential exposed group is bottle-fed infants from 0-6 months of age. This study was carried out by examining 17 different sources of potential exposure across nine age/gender groups in the German/Swiss/Austrian population.
The group had estimated mean dose rates of nearly 0.8 micrograms per kilogram body weight per day, well below the TDI.
However “it is of the same order of magnitude as recently reported concentrations that caused low-dose health effects in rodents,” as per the authors.
“In general humans in their developmental stages (fetus, infant, child) seem to be exposed more severely than adults,” written by Dr. Natalie von Goetz, senior scientist at the Swiss Federal Institute of Technology in Zurich.
Some studies have shown that polycarbonate bottles and containers tend to leach more chemicals when they are heated or any hot food product is introduced in it. In adults, the highest dose of BPA comes from canned foods. Some researchers demanded for additional research on production processes for canned soup and canned meat. The detail study has been published in the latest issue of the journal Risk Analysis.
