Greenpeace is wrong. The following explains why.
Exposure is minimal.
Greenpeace compares chewing on a toy to squeezing a sponge, and seeks to imply that the phthalate ester comes out of the toy just like water comes out of a sponge. In fact, the amount that comes out of the toy is extremely small. The amounts that come out are measured in micrograms. A microgram is one millionth of a gram, and a gram is less than one-tenth of an ounce. There is no human cancer hazard.
