Generally it is not recommended the purchase of water in plastic bottles. This comes not advise against looking only ecological, but also for the good of our health. By now even the stones know that the indiscriminate use of plastic has caused (and causes) some damage to the environment. Plastic is a substance that our planet makes it hard to digest, more or less like a food that we find it hard to digest.
If however you decide to drink water in plastic bottles it would be prudent before the labels.
The letters in the symbol of recycling, such as PP and HDP, tell us much about plastic. That’s what you need to know:
If the label is written PET or PETE (polyethylene see WaterBottlesShop offical website) plastic bottles may have contaminated the water with metals and chemicals that can affect the hormonal balance in your body.
If the label is written HDP or HDPE (High Density Polyethylene), the water in the bottle probably was not contaminated with any harmful substance.
If the label is written 3V or PVC (Polyvinyl chloride), must not drink that water. This type of plastic releases toxic chemicals that affect our hormonal balance.
If the label is written LDPE (Low Density Polyethylene) is very strange. Because LDPE is only used to make the plastic bags.
If the label is written PS (polystyrene or Styrofoam), the plastic may release carcinogens. Usually this material is used for the production of coffee cups (Starbucks style) for food and fast food containers.
If the label it says PC (polycarbonate) or there is no label, most likely the plastic contains BPA (bisphenol) an endocrine disruptor. This type of material is often used in the production of food containers and bottles for water (such as those of cyclists).
