HealthyStuff.org purchased products from Costco for the 2013 study of picnic supplies. Three of the four products in the study contained levels of chlorine above 3,500 ppm. Chlorine is likely associated with polyvinyl chloride (PVC), a widely used type
of plastic that is of concern to the environment and public health
during all phases of its life cycle. Flexible PVC contains chemicals called
phthalates, some of which have been associated with decreased fertility,
pre-term deliveries, and damage to the liver, testes, thyroid, ovaries,
kidneys, and blood.
