Polycarbonate (PC) and epoxy resin (EPX) is a typical thermal resistant plastic in our daily life. Careless or accident, waste plastic are flowing into ocean and constitutes a macro to nano-pollution. More serious is that hazardous chemicals such as bisphenol-A (BPA) derived from PC and EPX may seep out or generated from debris plastic to become potential sources. For clarifying the origin of BPA in the ocean, novel low temperature decomposition (temperature 50° to 300°C) are examined and calculated its kinetic parameters. In the ocean, 4,000 samples of sand and water were analyzed by GC/MS. BPA was detected in all samples. The mechanisms by which BPA is generated from plastics are matters which to date have not been addressed properly by any reports. The studies are revealed very much potential sources of contaminants even at low temperature, not to mention elevated temperature. It is easily predicted that BPA generate from plastics decomposition in long term and that it keeps contaminating in the world ocean.
