The study in Hebei province, China, employed stratified random sampling to interview 41 households and gather soil samples. Results showed that mulch-derived microplastics (MMPs) were abundant in Hebei province, with a particle size of 2.95 × 103 ± 1.75 × 103 μm, with only 18.8% derived from polyethylene (PE). The mass of MMPs was 2.90 ± 3.72 mg kg−1, and the proportion of PE MMPs was 43.75%. The use history of mulch film (HistMF) was found to be positively correlated to MMP abundance and inversely correlated to particle size, but not with MMP mass. The study also found no significant correlation between HistMF and PE abundance and mass. Findings from the study reveal that mulch-derived MMPs are not the primary source of MMPs in cultivated soil.
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[…]

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.
