This study investigates the microplastic drift from the Mekong River to Southeast Asia and the most exposed coastlines. Potential factors such as wind drift, rivers, vertical mixing, and sinking rates that affect plastic drift in the region were identified using the OpenDrift model with realistic wind and ocean currents for simulations between three months (summer and winter) and 15 months. The analysis revealed that seasonal drift is influenced by the monsoon systems and that most of the plastic gets stranded in the Philippines and Indonesia. In addition, vertical mixing and sinking rates are unknowns that affect the relative importance of wind drift (near the surface) and ocean currents. The plastic distribution was found to have large uncertainties but is seasonal and influenced by wind, vertical mixing, river discharge, and sinking rates. The Philippines and Indonesia were found to have coastlines that are most exposed to plastic pollution from the Mekong River. This study also shows that simulations of marine plastic drift are very variable, depending on many factors and assumptions. However, it provides more detailed information on marine plastic pollution in Southeast Asia and can help the concerned authorities take more practical actions.
The Ocean Plastics Charter aims to bring together leading countries, sub-national governments, businesses, and civil society organisations to commit to a more resource-efficient and sustainable approach to keep plastics in the economy and out of the environment. With this charter, it aims to transition to a more sustainable and resource-efficient method of managing plastics. Through[…]
These regulations are intended to promote sustainable development, food security, and the sustainable management of fishing activities in Palau’s waters. They also intend to create economic returns, employment generation, and export earnings from the sustainable harvesting of tuna and tuna-like species by encouraging the development of domestic fishing industries and a local tuna market. These[…]
This subchapter E of Title 40 of the Code of Federal Regulations outlines the pesticide programs, including registration and classification procedures, policies, special review procedures, standards, labelling requirements, packaging requirements, data requirements, and good laboratory practice standards. It also covers state registration of pesticide products, rules of practice governing hearings under the federal Insecticide, Fungicide,[…]
The Plastics Roadmap aims to decrease littering and other environmental harm brought on by plastics, prevent needless use, enhance plastic recycling, and replace traditional polymers derived from fossil fuels combined with various substances and liquids. To guarantee more focus on sustainable product development, reuse, product recyclability, and the growing usage of recovered plastics, these objectives[…]
The regulations aim to enhance aquaculture pollution prevention and control, protect aquatic ecosystems, ensure product quality and safety, and promote sustainable development. They consist of 24 articles divided into four sections: general provisions, delimitation of prohibited areas, pollution prevention and control, and environmental monitoring and supervision of fishery waters.
