In this study, atmospheric MP samples were collected and analysed from six sampling sites in the Wuliangsuhai Lake area from March to June 2021 to determine the atmospheric depositional fluxes of MPs to the lake surface. The average atmospheric depositional flux of MPs to the Wuliangsuhai Lake area (3371 ± 1423 n/d·m2) was found to be several times higher than the rates measured in other areas. MPs were predominately composed of small (0.05–0.5 mm) transparent fibers. The results of the study revealed that MPs were composed of either polyethylene (PE), polyethylene terephthalate (PET), or polystyrene (PS). The former polymer types indicated fibres from textile plants in adjacent cities, whereas the latter (PS) type is presumably derived from degraded food containers and other items associated with tourism. The presence of PE was also identified in association with thin films, which were likely to be derived from bags or agricultural plastics. The results derived from this study provide a theoretical basis for assessing atmospheric MP deposition within inland lake areas as well as for the prevention and control of MP pollution.
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.
