| Outline of Final Research Achievements |
Behavior and fate of plastic additive chemicals at their use, recycle, and disposal stage were investigated for the better understanding of their environmental risk. Firstly, information on plastic additives was collected to construct a chemical additive database. Secondly, we visited recycling, intermediate treatment, and disposal facilities of plastic wastes and collected information on how the plastics and additives were treated and disposed in those stages. Lastly, as a case study, we took phosphate flame retardants (PFRs) which are alternatives to brominated flame retardants. We studied their exposure and health risk to human in car cabin because a lot of plastics containing PFRs are used in cars. Our results indicated that current risk of PFR exposure through air and dust to human was negligible but we should be cautious as use of PFRs is increasing and PFRs may transform into more toxic chemicals.
