Original title: Solution Focused Risk Profile of Marine Plastic Litter and Global Framework
AI summary Read the abstract
This Japanese-language review article summarizes the global risk profile of marine plastic litter and the international regulatory landscape for managing it. It covers plastic discharge source profiles, multi-dimensional risk assessments of microplastics, environmental fate modeling, and approaches for prioritizing risk management interventions. The paper also reviews current international treaty negotiations aimed at reducing plastic pollution.
海洋プラスチックごみ問題が地球規模で課題となっており，解決に向けた取り組みを世界全体で推進することが求められている。本稿では現代社会におけるプラスチックの基盤的位置付けを踏まえつつ，海洋に排出されるプラスチックごみの排出源プロファイル，マイクロプラスチックの多角的リスクプロファイル，排出経路評価や環境影響評価の考え方，リスク管理の社会実装に向けた優先順位付けの考え方，および国際規制動向等を，総説的にまとめて解説する。
