[VII-05] Investigation on the actual condition of coastal microplastic on the sea shore of Kanto

*山口 晴幸1 (1. 元防衛大学校)

Keywords:microplastic, marine litter, sand beach, sea shore of Kanto

If marine trash is exposed to the sun, wind and waves while it is adrift, washed ashore or deposited on the seabed, it breaks into small pieces. Plastic particles less than 5 mm long is hazardous for marine life.
Present author emphasized it is critically important to retrieve waste plastics on the beach, or they break unto mps, which are too small to capture. Thus, regular and frequent beach clean-up is the basic measure to protect the marine environment.
