Microplastics are the emerging non-degradable pollutants in natural ecosystems. It impacts humans and wildlife, mainly aquatic species, by getting incorporated into the food chain due to their sizes (< 5 mm). Microplastics are common in the marine ecosystems but are also present in the freshwater ecosystems, such as in lakes, ponds, river basins, wetlands, or even in moist agricultural lands and groundwater. This paper focuses on the primary sources, detection, and quantification of microplastics in wetlands, both freshwater and coastal, based on research conducted worldwide. Fibers (thread), fragments, filaments, foams, and microbeads are common shapes of microplastics observed in wetland ecosystems. Microplastic pollution has been observed in wetlands with an abundance of up to 5531 particles m⁻³ and 6360 particles kg⁻¹ in water and sediment samples, respectively. This study also discusses the recent progress in extraction, characterisation, and quantification techniques in order to identify research gaps, such as the interaction of microplastics and heavy metals and organic compounds in the wetland ecosystem. Microplastics in the size range of 0.12–9.5 mm have been reported in wetland biota. Furthermore, ecological concerns are identified in terms of threats and disturbances caused by microplastics to the freshwater organisms present in wetlands. Finally, it outlines the future scope, research gap, and potential solutions for microplastic pollution research in wetlands.
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.
