Water consumed | Environmental science homework help

One potential source of pthalates is water consumed from plastic water bottles. But quantifying water consumption is not easy.

Consider your personal water consumption over the past 24 hours and contribute to the discussion; How many ounces of water did you consume?

• How many of these were from plastic bottles?
• Do you know if any of the bottles contained pthalates?
• How confident are you in this self report?
• If you were conducting a study, what might you do to  make the measure of pthalate exposure more accurate?
