re-using plastic bottles

Many are unaware of poisoning caused by re-using plastic bottles. Some  of
 you may be in the habit of using and reusing your disposable mineral water
 bottles (e.g. Nestle, Bisleri, Aquafina, Kinley, Evian,etc...), keeping
them
 in your car or at work. Not a good idea. It happened in Dubai, when  a 12
 years old girl died after a long usage(16months) of SAFA mineral water
 bottle, she used to carry the same fancy (painted by herself) bottle to
her
 school daily. In a nutshell, the plastic (called polyethylene
  terephthalate or PET) used in these bottles contains a potentially
 carcinogenic element (something called Diethyl-hydroxylamine 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. Better to invest in water bottles
that
 are really meant for multiple uses.This is not something we should be
 scrimping on. Those of you with family- do please advise them, especially
 children. This is a special warning for families in India who hang on to
 these disposable bottles and use them for cold water in their fridges  for
 ages. When a bottle looks a bit yellow- please get rid of it as a
 precaution.
