The announcement was made on Monday by Dr Aphichai Mongkol, Director General of the Department of Medical Science.
Emails, now dismissed as hoaxes, have been doing the rounds for a few years warning about the socalled dangers of plastic bottles, containers and films. The emails generally claim that reusing water bottles that have grown hot releases cancercausing chemicals called dioxins.
A study by Department of Medical Science found no dangers in drinking water from heated plastic bottles.
The experiment was conducted on 18 different brands of drinking water available in the market. The health scientists left the plastic bottles in the cars for one day and seven days before studying the cancercausing chemicals. They found no traces of dioxins.
