概要(目的・用途・実施内容)/ Abstract (Aim, Use Applications and Contents)
Microplastics and marine plastics are an increasingly important issue for environment and wellbeing. Here we investigate the degradation mechanism of common plastics found in the environment and the biodegradability under real life and laboratory conditions.
実験 / Experimental
Samples were collected at various locations in Japan and investigated by IR spectroscopy, optical microscopy and electron microscopy. Other, biodegradable plastics were subjected to various environmental conditions (river, lake, sea and soil) and analyzed as above.
結果と考察 / Results and Discussion
The commercial plastic samples were found to be oxidized at the surface and microscale flakes were observed to detach. Biodegradable plastics decomposed the fastest under laboratory conditions in sea water at 25°C. Samples kept in sea water in the ocean degraded ten times slower than the samples in the laboratory.
