According to a new study, pizza boxes could be harmful for health because of the presence of a group of chemicals, which were first introduced into different food containers. After health issues were raised over a chemical used in the production of Teflon, Perfluorinated compounds (PFCs) were introduced in several food containers.

Chemical company DuPont manufactures the hazardous chemical, known as C8 or PFOA. Nowadays, PFCs are used in different food containers, together with pizza boxes. Outdoor clothing also involves the use of PFCs.

A new report was released by the Environmental Working Group (EWB), which wrote regarding the risks identified by it that are associated with the use of PFCs.

Officials at DuPont announced that by the end of 2015, use of C8/PFOA would be stopped gradually, after they paid a $16.5 million settlement in a court case. But according to EWG, the company is turning its back on the public spotlight, in order to keep the public uninformed of what it is doing.

According to Bill Walker, consultant to the EWG, "We are deeply troubled that families have no way of knowing if they are being exposed to these chemicals in their own homes. DuPont continues to hide the truth about the health concerns of these new replacement chemicals".

Over 200 scientists came forward to demand limiting use of PFASs, which is another group of fluorinated chemicals.

Researchers wrote in a statement that it has been found in animal studies that some long-chain PFASs lead to disruption of lipid metabolism and the immune and endocrine systems, liver toxicity, adverse neurobehavioral effects, neonatal toxicity and death, and tumors in multiple organ systems. The statement has been published in Environmental Health Perspectives.
