Toxicity of plastics


Just found this too..

The peak, which is very dark in colour is the most environmental-damaging substance.

Note:
  1. Polyvinyl chloride (PVC) and other halogenated plastics
  2. Polyurethane (PU), Polystyrene (PS), Acrylonitrile-butadiene-styrene (ABS), Polycarbonate (PC)
  3. Polyethylene-terephthalate (PET)
  4. Polyolefins (PE,PP, etc.)
  5. Biobased Polymers (Bioplastics)
Which is the worst type? PVC plastic (vinyl) is the worst for both our health and for the environment because it is produced using chlorine, and it releases dioxins throughout its lifetime. Dioxin is cancer causing and is one of the most toxic chemical ever produced. It is very sad to say that the EPA suggests that there is no safe level of dioxin exposure. Also, dioxin is linked to cancer.

Some chemicals such as phthalates are added during the production of PVC as it is hard and cannot be utilised. This can hazardously harm our health when these chemicals leak out very easily from PVCs. Therefore, when young, immunocompromised children suck or bite these plastics (ie toys), they are also indirectly ingesting the harmful chemicals.

So, do take care!
