REUSE OF PLASTIC WATER BOTTLES
There is a huge controversy in Bangladesh regarding reuse of Plastic Water Bottles which is widely popular these days. The Daily Star has published an article claiming that there should be a statutory warning against reuse of this bottle.
Their concern is that several sources has confirmed:
The plastic (called 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 max, and keep them away from heat as well. Repeated washing and rinsing can cause the plastic to break down and the carcinogens (cancer-causing chemical agents) can leak into the water that you are drinking.
But some argue that US food and drug administration are allowing PET for food grade using & bottling medicine. So it is safe for multiple use.
Now the people are in a fix what to do who are so habituated in reusing plastic water bottles.
But before that many people are more concerned at the moment about another "Bottled danger".
