We all have a habit when we go out of home during the summer, especially on a longer walk to catch the first empty plastic bottle that will find and fill it with water. Look as quite common and normal thing, and in fact lies a great danger.
Perhaps you have not at noticing, but if you check the bottom of the bottle, you will notice some of the signs which indicate that the bottle is disposable, otherwise you may be toxic and cancerous.
Bottles that must throw away after the first use:
Almost all the bottles of mineral water, carbonated and non carbonated drinks that you buy every day are labeled PET or PETE.
They are intended only for single use. There is potential in each new water filling, plastic to emit heavy metals like antimony, a chemical compound EPA, which interfere with the action of the hormone. Such bottles can discharge carcinogens.
Bottles that are safe to use:
You will recognize them with these marks: HDP or HDPE, LDPE and PP or the numbers 2, 4, 5.
LDPE is a type of plastic which unfortunately is not used as much for producing bottles, but is more used for bags for packaging products.
HDP and PP are mainly white, and they are used for preparation of cups for yogurt.
Bottles that should be fully avoided:
It is a plastic with marks such PVC, PS, PC or numbers in the triangle such as 3, 6, 7. PVC releases two dangerous chemicals that interfere with the functioning of hormones in the body. Against that, this plastic is used for the production of bottles.
PS emits carcinogenic substance – styrene. Commonly used for making plastic coffee cups for single use or disposable packaging for the fast food.
PC (or no tags – no. 7) is the worst plastic for the packaging of food products because it emits dangerous chemical BPA. Unfortunately, it is used for baby containers, bottles for sportsman and dishes for preparing food.
After these warnings, it is better to check the casings before use.
