I am asking for help regarding a case study. It’s called What’s in my water bottle? by Janna R. Mclean. It has 2 parts with short answer. At the end is an essay about BPA level in plastic bottles. It’s about how plastic that we use particularly in water bottle is dangerous to our health. I am providing a link to the case study which can be downloaded. http://sciencecases.lib.buffalo.edu/cs/collection/detail.asp?case_id=461&id=461.
