Agricultural Plastic Pollution in China: Generation of Plastic Debris and Emission of Phthalic Acid Esters From Agricultural Films
|||||

Agricultural plastic films have been found to be quite useful, but they also pollute the environment with plastic waste and related toxins. Phthalates (phthalic acid esters, PAEs), an important additive of agricultural films, can potentially be released and contaminate the environment. In this study, agricultural plastic usage in China is being assessed and a method to estimate PAE emissions from agricultural films have been developed. The environmental fate of PAEs were evaluated using a fugacity-based multimedia model. The agricultural plastic film usage in China in 2017 was found to be 2,528,600 tons. During its lifetime, the agricultural film released a total of 91.5 tons of two typical types of PAEs. PAEs from the mulching film would mostly be removed through degradation, while those from the greenhouse film accumulate in vegetables. The findings from this study demonstrated the serious agricultural plastic pollution problem and associated PAE contamination in many regions of China.

Distribution and weathering characteristics of microplastics in paddy soils following long-term mulching: A field study in Southwest China

This paper reveals the status of microplastic pollution in paddy soil with long-term mulching. The study investigates the distribution and weathering characteristics of filmy microplastics in a mulched paddy field (non-mulched, four years of mulched, and ten years of continuous mulched soil were investigated) in Southwest China. The filmy microplastics accumulated annually in the plough[…]

Review of polymer technologies for improving the recycling and upcycling efficiency of plastic waste

The paper reviews advancements in polymer technologies that aim to improve the efficiency of recycling and upcycling plastic waste. Increasing the rate of recycling and upcycling is critical for addressing the issues caused by plastic pollution, and, at the same time, overcoming the technical limitations on the same. The research emphasises the need to develop[…]

Nanoplastics are significantly different from microplastics in urban waters

The study analyses the current advancements in the behavioural differences between MPs and NPs in urban waters. Analytical challenges, fate, interactions with surrounding pollutants, and eco-impacts of MPs and NPs are similarly discussed in this paper. It has been highlighted in the study that the characterization and fate studies of NPs are more challenging as[…]

Unfolding the science behind policy initiatives targeting plastic pollution

The study investigates scientifically evidence-based policy initiatives for targeting plastic pollution. The issue of plastic pollution is complex and still related to several uncertainties, which implies that policy initiatives must allow for flexibility and ongoing evaluations to adjust to the evolving knowledge generation. It is also important that the scientific community provide the needed research[…]
