Microplastic pollution promotes soil respiration: A global‐scale meta‐analysis

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(7)

Published: July 1, 2024

Abstract Microplastic (MP) pollution likely affects global soil carbon (C) dynamics, yet it remains uncertain how and to what extent MP influences respiration. Here, we report on a meta‐analysis determine the effects of microbiome CO 2 emission. We found that significantly increased contents organic C (SOC) (21%) dissolved (DOC) (12%), activity fluorescein diacetate hydrolase (FDAse) (10%), microbial biomass (17%), but led decrease in diversity (3%). In particular, increases components further promote emission (25%) from soil, with much higher effect MPs these emissions than biomass. The could be attributed opposite vs. diversity, as accumulation recruited some functionally important bacteria provided additional substrates for specific heterotrophic microorganisms, while inhibiting growth autotrophic taxa (e.g., Chloroflexi , Cyanobacteria ). This study reveals can increase by causing shifts microbiome. These results underscore potential importance plastic terrestrial fluxes, thus climate feedbacks.

Efficiency and costs of household filters for the retention of fibrous microplastics from the laundry process in Germany

Environmental Challenges, Journal Year: 2024, Volume and Issue: 15, P. 100919 - 100919

Published: April 1, 2024

Synthetic fiber fragments from household washing are one of many types microplastics that enter the environment. The potential and costs retention, using filters, were modeled for Germany. high indicate synergistic measures simultaneous retention different other sectors, such as road traffic, should not be overlooked in terms cost-effectiveness. Around 500 tons wastewater machines every year, which, around 91% is removed by conventional treatment. separation amount to approximately EUR 2.2 million per ton. widespread use filters already available on market households could increase proportion 96%. additional 114 would 37%. A comparison with tire wear reveals synergy potential. 20,000 tonnes subjected treatment same way fibrous process. One starting point, example, both can bypass plants environment so-called overflow if network overloaded. reduce input microplastics, reducing release through overflows, far exceeds savings individual installation households.

Micro/Nano-Plastic Pollution in Aquarium Systems

Advances in environmental engineering and green technologies book series, Journal Year: 2024, Volume and Issue: unknown, P. 225 - 256

Published: Sept. 25, 2024

Microplastics and nanoplastics (MPN) pose a growing threat to aquatic ecosystems, including closed systems like aquariums. This chapter delves into the various sources of MNPs in aquariums ranging from synthetic decorations fish food dustfall tap water. It explores fate transport these particles, settling, interaction with substrate, potential ingestion by organisms. The then dissects hazards MNP poses captive animals, encompassing physical harm, chemical toxicity, disruptions vital biological functions. proposes mitigation strategies such as MNP-free aquarium equipment, high-quality food, efficient filtration systems. emphasizes education awareness among hobbyists alongside standardized protocols for detection monitoring recognizing need further research. calls investigations long-term effects strategies.
