Many area unaware of poisoning caused by re using plastic bottles after emptying it. Reusing the disposable mineral water bottles (like Nestle, Bisleri, Aquafina, Kinley etc…), keeping them in your vehicle or at school or at work is not a good idea.The plastic(known as polyethylene terephthalate or PET) used in these bottles contains a potentially carcinogenic element ( Something called diethylhydroxylamine or DEHA). The bottles are safe for one-time use only. If you must keep them longer, it should be or no more than a few days, week maximum, and keep them away from heat as well. Repeated washing and rinsing can casue the plastic to break down and the carcinogens (cancer causing chemical agents ) can leak into the water that you are drinking. Better to invest in water bottles that are meant for multiple uses.
How To Avoid:
Check on the bottom of the bottle there is a triangle sign and there will be a number on it. If the number is higher than or equal to 5 -- then this bottle is safe to use.
Whatever number under 5 will release the chemical. For most bottle water,
the number is 1.
