Answer:

The common and convenient practice of drinking water and other beverages from plastic bottles comes with downsides.

Harmful Chemicals

Plastic drinking bottles contain many chemicals, some of which interfere with hormones in the body. These chemicals include bisphenol-A, or BPA, and phthalates, among others. Chemicals in the plastic can leach into bottled water, especially when exposed to heat or when the bottle is old. Different types of plastic—indicated by the number inside the triangle of arrows on the bottom of the bottle—contain different chemicals. Bottlers generally use the type of plastic labeled "1," and identified by the letters PET or PETE. Advocacy groups including the Natural Resources Defense Council and Sierra Club have pointed out evidence of harmful chemicals leaching into food or water and have called for further research to ensure safety.
