Are PLASTIC BOTTLES POISONING US? What Do Those Recycling Symbols and Codes at The Bottom Mean?

For some reason you don’t drink tap water, but you buy or pour it out of plastic packaging? Look at the triangle stamped on the plastic and the number in the middle. You might discover some shocking things.

You are only interested in the composition of the water, but you neglect the chemical composition of the packaging in which the water is? At the bottom of each package, look for the triangle with the number in the middle and find out how dangerous the plastic you are holding in your hands is.

1 – PET (often as PETE)

In most cases, these bottles are intended for single use. There is a possibility that it emits heavy metal antimony, the chemical substance EPA, which interferes with the hormone activity. These bottles can also discharge carcinogenic elements.


2 – HDP (sometimes as HDPE)

It is a “good” plastic, for which it is at least likely to release chemicals into the water.

3 – PVC (sometimes as 3V)

Emits two toxic chemicals, and both interfere with the functioning of the hormones in the human body. Nevertheless, this still is the most commonly used plastic for bottles.

4 – LDPE

This plastic does not release chemicals into the water. But imagine, it is not used for making plastic bottles, but mainly for making plastic bags for groceries.

5 – PP

This is another “good” plastic that usually has white or translucent color. It is used for bottles in which syrup is packed or cups for yoghurt.

6 – PS

It discharges into the water carcinogenic substance STYRENE. It is usually used in disposable coffee cups or in fast food packaging.

7 – PC (or no label)

This is the worst plastic for food products, because it secretes the chemical BPA. Unfortunately, it is used in baby bottles, sports bottles and containers for food storage.

It seems, therefore, that the chemicals don’t emit plastic 2, 4 and 5, or those labeled HDP, HDPE, LDPE, PP. the worst packaging is marked 1, 3, 6 or 7. In these bottles water is susceptible to chemicals or temperature action, and in the case of refill also bacteriological pollution.

    And they’re a recycling nightmare! Many of us grew up before there was such a thing as store-bought plastic water bottles. We really can survive without them.
