The study analysed soil samples from three fields covered with black mulch film for three years, with three fields without plastic use as a control. Visual plastic debris of size greater than 1 cm was collected, and mesoplastics between 2 mm and 1 cm were density separated using a sodium hexametaphosphate solution. The majority of macroplastics were found in fields previously covered with mulch films, with 80% identified as black PE film. The number of mesoplastics in plastic-mulched soil was 2.3 particles kg-1, while only 1.0 particles kg-1 were found in reference fields. The identified plastic levels are lower than those reported in comparable studies; results from the study suggest that plastic mulching functions as a source of plastic debris in agricultural systems. Due to its severely restricted degradability, these plastics are likely to accumulate in soil in the long term and further fragment into smaller and smaller debris.
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.
