In this study, three horticultural crops and earthworms were tested for perfluoroalkyl substances (PFASs) and halogenated flame retardants (HFRs) bioaccumulation. To represent the scenario using commercial biosolids as fertiliser, spinach (Spinacia oleracea) and tomato (Solanum lycopersicum L.) were grown in field soil with a single application of biosolids (at agronomic rate for nitrogen). Corn (Zea mays) was grown in spiked soil (50 mg PFOS/kg soil, 5 mg Deca-BDE/kg soil, and a mixture of both, 50 mg PFOS and 5 mg Deca-BDE/kg soil) to represent the worst-case. To study soil invertebrates’ bioaccumulation, earthworms (Eisenia andrei) were subjected to spiked corn soil. The results from the study revealed that PFASs had larger transfer factors (TFs) than PBDEs in all crop plants: 2 to 9-fold in spinach, 2 to 34-fold in tomato, and 11 to 309-fold in maize. Earthworms were found to have greater bioaccumulation factor (BAF) values for PFASs compared to PBDEs.
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.
