Abstract Microplastic and nanoplastic contamination is widespread affects aquatic terrestrial ecosystems. Photosynthetic organisms are present in both media, they primary producers, sink for CO 2 , represent a major point of entry the food chain. Here, current knowledge on fate impacts microplastics nanoplastics interaction with these reviewed. As general trend, plastic characteristics (smaller size positive charge) play crucial role their toxicity toward photosynthetic organisms. Plastic leachates (containing additives) also source toxicity, some harmful compounds such as phthalate esters shown to accumulate plants generate risk consumers. Adsorption particles evidenced each type organism, uptake translocation nanoplastics, leading concerns trophic chain contamination. The available techniques detection secondary products biological samples media listed. Finally, gaps knowledge, specific challenges, future research directions discussed.

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

Environmental Science & Technology, Journal Year: 2021, Volume and Issue: 55(18), P. 12459 - 12470

Published: Sept. 13, 2021

Agricultural plastic films have been proven highly advantageous, but they also cause pollution of debris and associated chemicals. Phthalates (phthalic acid esters, PAEs), an important additive agricultural films, can be released contaminate the environment. Here, we analyzed usage assessed in China developed a method to estimate PAE emissions from films. Additionally, environmental fate PAEs was evaluated using fugacity-based multimedia model. The film 2017 2,528,600 tons. After recycling water erosion, amount estimated as 465,016 erosion process carried 4329 tons into aquatic During its lifetime, total 91.5 two typical types PAEs. mulching would mostly removed through degradation, while those greenhouse accumulate vegetables. Populated regions exhibited more serious vegetables with no immediate health risks. model well comparable measured concentrations uncertainty analysis based on Monte Carlo method. findings this study demonstrate problem contamination China.

Risk Assessment of Agricultural Plastic Films Based on Release Kinetics of Phthalate Acid Esters

Environmental Science & Technology, Journal Year: 2021, Volume and Issue: 55(6), P. 3676 - 3685

Plastic films have become an integral part of fruit and vegetable production systems, but their release phthalate acid esters (PAEs) is a threat to human health. The kinetics PAEs measures risk are still not well understood. We investigated 50 agricultural films, with concentrations ranging from 2.59 282,000 mg kg–1. seven commercially available film types included were polyvinylchloride (PVC), metallocene polyethylene (mPE), ethylene vinyl acetate (EVA), polyolefin (PO), three mulch films. Bis(2-ethylhexyl) (DEHP) was detected in most its fitted into the first-order kinetic model. rate DEHP negatively related thickness. potential carcinogenic risks air six kinds plastic greenhouses health estimated. found that associated PVC mPE greenhouse warrant greater attention. Though EVA, PO greenhouse, lower risk, we advise keeping ventilated during first month use reduce direct exposure volatile PAEs.

The extracellular enzymes secreted by soil microorganisms play a pivotal role in the decomposition of organic matter and global cycles carbon (C), phosphorus (P), nitrogen (N), also serving as indicators health fertility. Current research is extensively analyzing these microbial populations enzyme activities diverse ecosystems climatic regions, such forests, grasslands, tropics, arctic regions deserts. Climate change, warming, intensive agriculture are altering activities. Yet, few reviews have thoroughly explored key required for fertility effects abiotic factors on their functionality. A comprehensive review thus essential to better understand C, P, N cycles, response climate changes, ecosystems, farming, fertilization. Studies indicate that temperature, moisture, water content, pH, substrate availability, average annual temperature precipitation significantly impact Additionally, change has shown ambiguous activities, causing both reductions enhancements catalytic functions.

Effects of microplastics on soil carbon pool and terrestrial plant performance

Carbon Research, Journal Year: 2024, Volume and Issue: 3(1)

Published: April 19, 2024

Abstract Soil, as a primary repository of plastic debris, faces an escalating influx microplastics. Microplastics have the potential to decrease soil bulk density and pH, well alter pore structure aggregation. These changes in physicochemical properties subsequently lead habitat degradation for microbes environmental shifts that impact plant growth. Masquerading carbon storage, microplastics can distort assessments pool by introducing plastic-carbon associated leachates, influencing organic matter (SOM) turnover through priming effects (e.g., dilution, substrate switching, co-metabolisms). Additionally, influence distribution particulate mineral-associated matter, consequently affecting accumulation stability carbon. Furthermore, also chemodiversity dissolved (DOM) soils increasing DOM aromaticity molecular weight while deepening its humification degree. The observed may be attributed inputs from microplastic-derived along with organo-organic organo-mineral interactions coupled microbial processes.
