On Monday the environmental activist group Greenpeace issued a report stating that Apple’s iPhone contains toxic chemicals. Now the California-based environmental group, Center for Environmental Health, is threatening the Cupertino-based company with a lawsuit based on the Greenpeace report.

The private organization claims Apple is selling the combination iPod and smart phone in violation of California law. The law in question, Proposition 65, requires companies to warn consumers that it is exposing them to certain levels of specific chemicals.

In this case, Center for Environmental Health claims that the Greenpeace report shows the iPhone includes phthalate levels that are above the Proposition 65 threshold.

The group has given Apple a 60-day notice of the violation, after which it can file a lawsuit against the company.

Center for Environmental Health spokesperson, Caroline Cox, commented "Basically, what we’re saying in our notice of violation is that [the iPhone] exposes a user to a level above" Proposition 65 limits.

The group is hoping to negotiate a settlement with Apple instead of going to court. In this case, the company wants Apple to agree to recall every iPhone already sold and to post a warning on the packaging for future iPhone sales until the chemicals are completely removed from the product.
