Health Concerns
In 2008, researchers in Canada asserted that quaternary ammonium biocides and oleamide were leaking out of certain polypropylene labware, affecting experimental results. As polypropylene is used in a wide number of food containers such as those for yogurt, Health Canada media spokesman Paul Duchesne, said the department will be reviewing the findings to determine whether steps are needed to protect consumers.
The Environmental Working Group classifies PP as of low to moderate hazard. PP is dope-dyed, no water is used of its dyeing in comparison for example with cotton.

Famous quotes containing the words health and/or concerns:
“We are conscious of an animal in us, which awakens in proportion as our higher nature slumbers. It is reptile and sensual, and perhaps cannot be wholly expelled; like the worms which, even in life and health, occupy our bodies. Possibly we may withdraw from it, but never change its nature. I fear that it may enjoy a certain health of its own; that we may be well, yet not pure.”
—Henry David Thoreau (1817–1862)
“American thinking, when it concerns itself with beautiful letters as when it concerns itself with religious dogma or political theory, is extraordinarily timid and superficial ... [I]t evades the genuinely serious problems of art and life as if they were stringently taboo ... [T]he outward virtues it undoubtedly shows are always the virtues, not of profundity, not of courage, not of originality, but merely those of an emasculated and often very trashy dilettantism.”
—H.L. (Henry Lewis)
