The current study quantifies microplastic concentrations and types (i.e., beads, fibers, films, foams, and fragments) in nine Indiana watersheds, representing a gradient of dominant land use (i.e., agricultural, urban, and forested). It was predicted that microplastic concentrations would be higher in watersheds with higher percentages of urban and agricultural land use than in forested watersheds. However, the results from the study revealed the presence of measurable quantities of microplastics in samples from all watersheds, with the microplastic concentration being constant with land use or longitudinally within watersheds. Fibers were found to be the most dominant form of microplastic at all sites and were transported primarily through atmospheric deposition rather than via direct runoff from the surrounding landscape. The study also highlighted that rivers have a different microplastic “signature” than large lakes, likely due to the retention characteristics of flowing water ecosystems, unique microplastic sources, and a shorter legacy of microplastic 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.
