Everyone is aware that drinking water has many health benefits. Nowadays it is the norm to carry drinking water wherever we go. Bottled water is available everywhere from grocery stores to restaurants, movie theaters, schools, colleges, etc. The main question here is how safe is bottled drinking water?
Let’s take a look at some hazardous effects of drinking water stored in plastic bottles.
Bisphenol A (BPA) is a chemical which is used to stabilize epoxy resins and polycarbonate plastics. It is also used in softer plastics in order to prevent cracking. Plastic used for bottled water usually contains BPA. When these plastic bottles are exposed to heat this chemical leaches into the water. Drinking this water creates ‘faux estrogen’ or bad estrogen. High levels of bad estrogen may result in ovarian, prostate, and breast cancers.
BPA is also known to have adverse effects on foetuses, babies and children’s brain development and prostate glands. Behavioural disorders such as hyperactivity and aggression in children are other effects of BPA. BPA also affects the endocrine glands and the reproductive systems leading to prostate cancer and ovarian cancer.
Polyethylene Terephthalate (PET) – PET bottles are known to be BPA-free but they do pose other potential health risks. According to research PET bottles contain contaminating particles of faecal matter, saliva and food residues in the plastic hence reusing such bottles can cause health threats. Soft plastics are difficult to clean hence they are harmful if reused.
Phthalates is another chemical compound which is used to make plastic flexible. These also leach into the water contained in their bottles. The problems they cause in humans include: liver cancer, testicular atrophy, and sterility in males.
