In this study, a pot experiment was conducted to investigate the phytotoxicity on seed germination and seedling of two rice varieties. The results showed that as soil Dechlorane Plus (DP), Tetrabromobisphenol A (TBBPA), and Cd concentrations increased, germination rate, germination index, and vigour index of the two varities decreased, with Number 7 rice being most affected. Halogenated flame retardants and Cd in soil increased root activity and proline and decreased protein and soluble sugar in two rice varieties. Furthermore, the two rice variety seedlings responded differently to contaminants. Two rice varieties have increased superoxide dismutase (SOD) activity and caused a lot of malonyldialdehyde (MDA). In Number 7 rice, DP and TBBPA enhanced catalase (CAT) activity, but in Number 1, DP increased and TBBPA inhibited it. DP and Cd bioaccumulation factors were 0.025–0.042 and 6.59–14.20, biotransport coefficients 0.39–0.48 and 0.034–0.087. The Number 1 rice bioaccumulated TBBPA and Cd better than the other rice kinds, while DP bioaccumulated similarly. The findings from this study can help assess the ecological dangers of two halogenated flame retardants and Cd in plants.
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.
